'''''Mario Party 9''''' is the ninth home console installment of the [[Mario Party (series)|''Mario Party'' series]] and the second and final installment for the [[Wii]]. The game was the first in the series to be developed by [[NDcube]] instead of [[Hudson Soft]], as a result of the latter's acquisition by [[Konami]]. It is also the sixteenth in the series overall. The game was released on March 2, 2012 in Europe, in Australia on March 8, 2012, in North America on March 11, 2012, and in Japan on April 26, 2012. The host of the game is a yellow [[Toad (species)|Toad]] for the boards while a blue Toad is the host for minigames, and a green Toad appears near the end of boards to initiate an event similar to the [[Last Five Turns Event]] from past ''Mario Party'' games. This is also the twenty-fifth and final installment of the ''Super Mario'' franchise overall to be released for the Wii console. 

==Story==
[[File:MP9 Bowser Stealing Mini Stars.png|left|thumb|200px|Bowser stealing the Mini Stars using a vacuum machine]]
On a night outside of [[Peach's Castle]], [[Mario]] and his friends are gathered to watch the [[Mini Star]]s glitter in the sky. As Mario peers though the telescope, he is shocked as he notices that the stars are suddenly being sucked through a vortex. It is then revealed to be [[Bowser]] and [[Bowser Jr.]] on a spacecraft, who are using a vacuum-like machine to suck the Mini Stars out of the sky and into containers. Witnessing this, the player's character rallies everyone into setting out to defeat Bowser and save the Mini Stars. As they start their journey, [[Shy Guy]] and [[Kamek]] appear from the woods and infiltrate their group as part of Bowser's plan.

Before each board, there is a cutscene that features Bowser admiring his collection of Mini Stars (or fuming in the last two). Bowser Jr. then runs over to inform his father the progression of the player's group. Bowser is enraged, but confidently summons two of his minions to stop the group before they can take all the Mini Stars. Eventually, however, the group reaches Bowser's space lair, [[Bowser Station]], and face Bowser Jr. before battling his father.

After the final battle with Bowser, the player looks out from the stadium at Bowser's other platform, where the canisters containing all the Mini Stars burst and release them back to where they once were. As this happens, Bowser and Bowser Jr. are flying off. Bowser is mourning over the failure of his plan, which he reveals was to decorate his castle using the Mini Stars. However, upon seeing the released Mini Stars, Bowser is enraged and chases off the ones that fly near him. However, this only results in him falling out of his Koopa Clown Car; Bowser Jr. flies down to save him. Back at Peach's Castle, Mario and friends are once again gathered around the telescope to admire the Mini Stars as they glisten in the night sky.

==Gameplay==
[[File:MP9 Bob-omb explosion.jpg|thumb|200px|left|[[Waluigi]], about to lose half of his Mini Stars at [[Bob-omb Factory]].]]
In ''Mario Party 9'', a new form of gameplay was introduced in this game, retiring the old format seen in the prior eight titles: players move all at once through the board in a vehicle (a car in Toad Road, a magic carpet in Boo's Horror Castle and a legged machine in Bob-omb Factory, for example), still taking turns rolling, moving from a starting point to an ending point. Instead of rolling a die with a 1-10 on it like in the previous games, players can only roll a dice block with a 1-6 on it; however, there are other dice blocks that can be collected, which includes a dice block that allows a 1-10 roll. Instead of trying to collect coins to buy stars, players receive [[Mini Star]]s if they pass by them. While doing so, players must also try to avoid [[Mini Ztar]]s, which deduct their current amount of Mini Stars. The player who collects the most Mini Stars by the end of the game is declared the winner.

New minigame types are introduced in the ''[[Mario Party (series)|Mario Party]]'' series, one example being 1 vs. 2 minigames against [[Bowser Jr.]] Unlike in previous games, players do not compete in minigames after every player has moved, instead only when a minigame is triggered from the space that is landed upon. Also, when receiving dice blocks, a minigame may pop up afterwards. Unlike previous ''Mario Party'' games, where often only the winner(s) of a minigame receives a reward, all [[minigames]] are ranked from first to last place and generally all players receive Mini Stars, with players in a higher position earning more Mini Stars.

During a party, there are two board events that are required to occur before advancing: Captain Events and Boss Battles. The former occurs whenever a player arrives on a Captain Event Space. The event differs for each board, but they all allow the players to earn more Mini Stars, though the player that has started the event always has some form of control over the event, putting him or her in an advantage state. As for Boss Battles, there are two Boss Battle Spaces on every board, one near a fortress and one at the end. During the Boss Battle minigames, players must work together to defeat a boss while attempting to increase their own individual scores, as the player with the highest score wins the minigame, which gives more Mini Stars than normal.

===Modes===
[[File:MP9 Main Menu.png|thumb|The Main Menu]]
====Party mode====
Once again returning from previous ''Mario Party'' games, Party Mode involves the players going around the board like with the previous games, but changed due to the new gameplay mechanics of ''Mario Party 9''. The amount of Party Points that the players earns is determined by how many Mini Stars they have at the end of the game. However, if handicaps are used, the handicap amount does not count towards the Party Point total; for example, if a player has a 50 Mini Star handicap, and finishes with 100 Mini Stars, they only earn 50 Party Points. Notably, should a player end a game with less than 10 Mini Stars, 10 Party Points are added regardless of how low their Mini Star count is. This is independent for each player that ends with under 10 Mini Stars (for example, a 4-player game that ends with Mini Star counts of 105, 67, 60 and 3 without any handicaps gives a total of 242 Party Points although the Mini Star total is only 235).

====Solo mode====
The game's story mode, Solo Mode, involves the players traveling across all six boards to defeat Bowser, Bowser Jr., Kamek, and Shy Guy and save the Mini Stars. Completing Solo Mode awards the player 500 Party Points, and the Mini Star grand total is also be added onto the player's Party Point amount; for example, finishing Solo Mode with a grand total of 500 Mini Stars awards the player 1000 Party Points. Shy Guy and Kamek or both appear in all six boards as CPU players competing against the player.

Also, instead of always playing against three other computer players in a four-player match on each board, sometimes, the player plays a three-player match against two computers, or a two-player duel match against one computer (either Kamek or Shy Guy). The minigames for the three-player matches are Free-for-all minigames and 1 vs 2 minigames, and all minigames in two-player matches are Free-for-all minigames, adapted for duels. The award system for minigames in a three-player match is five stars for first place, three stars for second place, and one star for third place, and the award system for minigames in a two-player duel match is five stars for first place and one star for second place. The player often has at least one ally on four boards; if they win instead of the player, then they can still continue to the next board regardless of their final position. If Kamek or Shy Guy wins, then they take all the Mini Stars from the other players and the player must replay the board, similar to a [[Game Over]]. If Kamek or Shy Guy ties with the player or an ally, the player still continues to the next stage.

====Minigame mode====
[[File:MP9 Free Play Mode.png|thumb|Free Play mode]]
In the minigame mode, players can play various different game modes involving minigames. A blue [[Toad (species)|Toad]] is the host of Minigame Mode. When finished, all game modes award 10 Party Points, except for Free Play, which awards just 1 Party Point per finished minigame.

=====Free Play=====
In the Free Play mode, the players can freely play any minigames they already unlocked in Party Mode.

=====Step It Up=====
{{quote|Be the first player to win a certain number of minigames to become the champion!|In-game description|Mario Party 9}}
[[File:MP9 Step It Up.png|thumb|[[Birdo]] playing Step It Up]]
Step It Up is a returning game mode from ''[[Mario Party DS]]''. As before, players must climb to the top of a staircase by winning minigames; however, in ''Mario Party 9'', this mode can be played by two or three players, players advance up to four steps when winning a minigame as opposed to one, and the last place player selects a random minigame from a roulette wheel. Some minigames, such as [[Logger Heads]], [[10 to Win]], [[Snow Go]] and [[Pizza Me, Mario]], have unique versions in this mode. In these minigames, once a player completes the goal, the minigame ends; in other modes, other players are still active even after the goal is completed. If everyone wins, everyone gets to climb the stairs. If a minigame ends in a draw, no one climbs up any stairs. Players can select whether they want 3, 5, or 7 minigame wins required for victory. Whoever gets to the top first wins and is greeted by a number of celebrating [[Whittle]]s if they get first to 3 wins. If the player gets first to 5 wins, a large silver statue of the winning character is seen. If the player gets first to 7 wins, the statue is gold. 

The background of Step It Up resembles [[Tall Trunk Galaxy]] from ''[[Super Mario Galaxy 2]]'', with more Whittles clapping in the background.

=====Garden Battle=====
[[File:MP9 Garden Battle Mode.png|thumb|200px|Garden Battle]]
Garden Battle is a mode that can be played by up to four players. The objective in this mode is the players must fill up their garden with groups of colored plant blocks. The plant groups are randomly chosen from a large cart, and the player who places in first in the previous minigame chooses their plant groups first, followed by second place, then third, then last. If everyone is tied for either first or last place, no one puts any plant blocks. A minigame starts when a player chooses one in the minigame wheel. The player who picks the minigame is at first chosen at random, and then the succeeding choices are made by the player who places in last at the preceding minigame.

The plant groups must be able to fit in their garden, or the player does not have a chance to place one in the patch. The game is won when a player completely fills their garden with plants.

The winner has their flowers bloom with the middle one being the biggest. They then do their victory animation and the losers, as well as the yellow and blue Toad, applaud the winner. If the game is played with fewer than four players, the green Toad applauds the winner too.

=====Choice Challenge=====
{{quote|Players choose three out of five minigames. Points are awarded based on the results of each minigame. The player with the highest total at the end is the champion!|In-game description|Mario Party 9}}
[[File:MP9 Choice Challenge Scoring.jpg|thumb|Choice Challenge]]
Choice Challenge is a game mode that can be played by up to four players. Five free-for-all minigames are randomly chosen, and each player selects three that they would like to play by pressing a corresponding button on the [[Wii#Wii Remote|Wii remote]]. One minigame is announced before the players make their selection as the Chance Minigame; this minigame is worth extra points for the first place player, but normal points for other players.

The players hide in [[Warp Pipe]]s and emerge only when a minigame they are playing is announced, so it is not clear who is competing in each until then.

The minigames are played in the order of how many players selected it, starting at the least and working up to the most. If only one player selects a minigame, that player is automatically awarded first place points without competing. Sometimes, a character appears out of a pipe when they are not participating in the minigame. If that happens, the blue Toad apologizes for his error and corrects the mistake.

Points are awarded for place in minigames, and standings are announced after each minigame. The players with the most points at the end win. The most points a player can score is 350, while the least is 30. It is possible for all four players to win. The losing players emerge out of their pipes in the order of their point totals (from lowest to highest) and perform their losing animation as their points are displayed. The winning players jump out of the golden pipe and perform their victory animation.

=====High Rollers=====
{{quote|Play minigames to determine the order in which players roll around the board to pick up points. The first player to reach 500 points is the champion!|In-game description|Mario Party 9}}
[[File:MP9 High Rollers Mode.png|thumb|200px|High Rollers]]	
High Rollers is a game mode that can be played with up to four players. In this mode, players compete in a series of minigames to gain up to 500 points by rolling their cube over the panels worth 30, 20 or 10 points. The board is composed of 20 panels and the [[POW Space]] in the center. When a player rolls over a number panel, the amount of points it gives a player decreases by 10. When a panel reaches zero, after everyone moves, the blue Toad resets the panel's value to 30.

The number of spaces the player can move depends on what place they get in the previous minigame. First place is allowed to move four spaces, second place moves three, third place moves two, and last place only moves one. The selected player chooses a minigame by stopping the Minigame Wheel. The player who picks first is selected at random, then the succeeding choices are made by the player who finished last place in the last minigame. Any ties are settled by rolls via [[Dice Block]]s. When there are four players, if there are ties for both first place and last place, the first place players roll first and the players in last place roll next. However, if everyone finished first or last in a minigame, no one moves any spaces.

When a player rolls over the POW Space in the center of the board, every panel's point value is decreased by 10. If a block is at zero, then its value resets to 30. The POW Space can only be used by one player per turn, and is first active when everyone has taken their first turn.

Finally, when there is a 100-point gap in between players, the losing players gain a Boost item, which allows them to dash across the board, rolling over number panels and pushing off other players in their way, without using up a space to move. Players who are knocked off the board are unable to take their turn. When they do get a turn again, they land on the POW Space, activating it if it hasn't already been. If a player is blocked by other players and cannot move, they are teleported to the POW Space.

The game ends when one player gets 500 points or more.

The winner gets to go in the hot-air balloon with the blue, yellow, and green Toads while the others hang on to the string underneath the balloon.

=====Time Attack=====
{{main|Time Attack (Mario Party 9)}}
Time Attack is a single player mode. The objective of this mode is to beat the ten given minigames in the quickest amount of time, while earning Challenge Bonuses from completing the Bonus Objectives in each minigame. Earning a Challenge Bonus cuts three seconds off the player's completion time for that minigame.

=====Boss Rush=====
{{quote|Compete for Points in a series of six or twelve Boss Battles. The Player with the most points at the end is the champion.|In-game description|Mario Party 9}}
[[File:MP9 Boss Rush Mode.png|thumb|200px|The hub of the Boss Rush game mode]]
Boss Rush is a game mode that can be unlocked by purchasing it for 500 Party Points in the museum after the player beats Solo mode, and allows up to four players. In this mode, players compete against each other in six or twelve boss minigames to see who can receive the most points at the end of the game. If the player finishes first in a minigame, they receive five points; finishing second gives them three points; third gives the player two, and fourth gives the player one.

The player has the option to play against either the mid-bosses, the stage bosses, or all bosses. The bosses are fought in the same order as Solo Mode. [[Diddy's Banana Blast]] and [[DK's Banana Bonus]] are not fought in Boss Rush, due to the fact that despite being categorized as boss minigames, they are just bonus minigames, and Donkey Kong and Diddy Kong are not faced during them. The player with the most points at the end is the winner.

====Museum====

The Museum is where the players can spend Party Points to buy various things such as [[List of constellations in Mario Party 9|Mini Star constellations]], game sounds, vehicles or extra game modes. They can also watch the credits from here. Once they return a constellation into the sky, the players can go to  see it in the sky.

====Extras====
In Extras, the player can play through various extra minigames such as [[Castle Clearout]], [[Shell Soccer]] or an extended version of [[Goomba Bowling]]. There is also a mode called [[Perspective Mode]], in which the player plays through ten minigames that have a modified camera angle, making them harder to win.

===Playable characters===
There are a total of 12 playable characters in ''Mario Party 9'', consisting of ten default characters and two unlockable characters, [[Shy Guy]] and [[Kamek]], who must be unlocked by completing Solo Mode. [[Koopa Troopa|Koopa]] is fully playable for the first time in the series, while Kamek also makes his playable ''Mario Party'' debut. Due to their roles as opponents in Solo Mode, neither [[Shy Guy]] nor Kamek are playable in that mode. Shy Guy, previously playable in ''[[Mario Party 4]]'''s [[Beach Volley Folly]] minigame, is also considered a new playable character.

==Boards==
'''Note:''' There are three different exclusive vehicles for each board, one available from the start and the other two purchasable from the Museum for 200 Party Points each. They all function identically, but their type depends on the board (for example, cars are used throughout Toad Road). The third vehicle is  based off of the stage boss.

It is designed after [[World 1 (New Super Mario Bros. Wii)|World 1]] from ''[[New Super Mario Bros. Wii]]'', and features lush grassland, flowers and windmills. A broken bridge prevents players from moving forward, and if the players fail to roll a certain total number, they fall to a lower route filled with [[Mini Ztar Space]]s.

The Captain must avoid getting hit by magma, or they lose half of their Mini Stars. In Solo Mode, both [[Kamek]] and [[Shy Guy]] will appear; if they are the only opponents, this ensures the player will have to be the Superstar to move on.

==Minigames==

{{main|List of Mario Party 9 minigames}}
''Mario Party 9'' has a total of 78 main minigames, as well as [[Castle Clearout]], [[Shell Soccer]] and an extended version of [[Goomba Bowling]] playable only in Extra Mode. There are 44 Free-for-all minigames, 10 1-vs-Rivals minigames, 14 Boss Minigames (Including [[Diddy's Banana Blast]] and [[DK's Banana Bonus]]), and 10 newly-introduced Bowser Jr. minigames, in which two players team up against [[Bowser Jr.]] All of the minigames, apart from the extra ones, are playable during various events in the parties, in the various modes of Minigame Mode and a select ten with a single player in the new [[Perspective Mode]], which uses a different camera angle from the one normally seen when playing the minigames.

==Items==
Instead of more traditional items, ''Mario Party 9''<nowiki>'</nowiki>s items consist entirely of [[Dice Block]]s, allowing the user to roll a specific number more easily from a specific range of values. These can be obtained by landing on a [[Special Dice Block Space|Dice Block Space]].

==Spaces==
[[File:MP9 Prerelease Magma Mine.png|thumb|200px|[[Magma Mine]]]]
When a player lands on a space, something is going to happen. Each space has its own effect, but like in previous ''Mario Party'' games, every space is color-coded. The color of the space tells what kind of event is going to happen.
*Normal Spaces
**'''Blue Spaces''' - Triggers good events and helps the player who landed on it.
**'''Red Spaces''' - Trigger bad events and hinders the player who landed on it.
**'''Green Spaces''' - Neutral spaces that often lets one or all players attend an event that can either help or hinder the player.
**'''Yellow Spaces''' - Trigger minigames when landed on.
**'''White Spaces''' - Adds Mini Stars to the Jackpot on the Bowser Station board.
*Star Spaces
**'''Mini Star Spaces''' - Gives Mini Stars to the player who landed on it.
**'''Mini Ztar Spaces''' - Takes Mini Stars from the player who landed on it.
If the player moves over a space with a prohibitory sign on it, they automatically stops at that space and an event starts. The only two spaces of this kind are the Boss Space and the Captain Event Space.

Because of the new rules in ''Mario Party 9'', there are many new spaces introduced. Some old spaces returned as well, but some have a different effect (for example the [[Blue Space]]). With a total of 21 different kind of spaces, ''Mario Party 9'' has the most spaces of the series. Also for the first time in the ''Mario Party'' series, some spaces are unique for a specific board.  Here is a list of all the spaces in the game, with what kind of effect they have.

==Differences from previous ''Mario Party'' games==
This is the first ''Mario Party'' in the series: 
*to not be developed by [[Hudson Soft]].
*to have [[Mini Star]]s instead of [[coin]]s and [[Star (Mario Party series)|Power Stars]].
*to change the core board gameplay by having all the players together in one vehicle.
*to not have [[Red Space]]s, replacing them with Mini Ztar Spaces.
*to not include Advice or Hints in the Minigame Rules Screen. 
*to not include a category of 2-vs-2-Minigames, and the first since ''[[Mario Party 2]]'' to not include a category of Duel Minigames (if the 1-vs.-1 Story Minigames and/or the etc. Minigames from ''Mario Party 4'' are counted as Duel Minigames). Additionally, it does not have the team battle mode first introduced in ''Mario Party 4''.
*since ''Mario Party 2'' to have only one save file instead of three.
*since ''Mario Party 6'' to not feature [[Toadette]] in any capacity.
*to not use the usual ''Mario Party'' font for the in-game text in any way.
*to use the [[List of fonts#Modern Super Mario typeface|modern font]] for the in-game text, first used in ''[[Super Mario 3D Land]]''.
*to not save game progress after every turn, instead saving after the game is over.
*to not start out with a 1-10 Dice Block.
*to have fewer playable characters than its numbered predecessor.
*since ''Mario Party 3'' to have a unique Superstar animation.
*to allow the player to progress in the Solo Mode without winning on a board (as the player can still progress when achieving a tie or when an ally wins on a board).
*to have a separate win screen after a minigame ends, instead of the traditional minigame endings.

GameSpot gave it a 6.0 explaining that it is too familiar and that Solo mode is tedious and required for unlocks. Game Informer gave the game a 5.75/10, explaining that the game relies far too heavily on luck and can make for a "disheartening experience."<ref>[http://www.gameinformer.com/games/mario_party_9/b/wii/archive/2012/03/09/mario-party-9-review-a-small-step-towards-positive-change.aspx Game Informer Score for ''Mario Party 9''.] ''Game Informer''. Retrieved June 29, 2017.</ref> Destructoid gave the game a 7.5/10, praising the reduction of motion-control minigames, and saying that many of the minigames feel like true ''Super Mario'' experiences and not ''Super Mario'' versions of party games, and that the influence of ''[[New Super Mario Bros. Wii]]'' and ''[[Super Mario Galaxy]]'', and to a lesser extent, ''[[Super Mario Sunshine]]'', is "pretty much the game's central theme," and that it feels more like an "honest-to-god" ''Super Mario'' game than the other entries, but complained that the game is still determined a lot by chance.<ref>[https://www.destructoid.com/review-mario-party-9-224500.phtml Destructiod score for ''Mario Party 9''.] ''Destructoid''.

|align="left"|"''The Mario Party games are meant to be played with a room of friends (and the total lack of online play reflects this). But every party will always be subverted by this entry's reliance on randomness to "shake things up," as Bowser puts it when he is about to do something awful to you. This is especially irksome for me because I can envision what Mario Party 9 could be -- a clever, strategic board game with mini-games interspersed would be truly awesome.''"

|align="left"|"''Overall, Mario Party 9 is a decent package with a lot of content, even if the Story mode is something you'll wish you could avoid. It's colorful, good looking, and fun with others, but after so many games, the appeal just isn't going to last for many people. There's no denying that what Mario Party 9 does, it largely does well; it's just that it's largely been doing it well for nine console games and two handheld games. Once you've spent a few hours with mates, seen all the different boards, and played all the minigames, there's very little incentive to return. Much like that high school reunion, it is fun for a night, but you won't have any hesitation about moving on.''"

While an early version features the same layout and many of the same features, the "9 Island" seen in the final game is not present, featuring a circular island in its place. The circle island on the final board also replaces a mountain with a waterfall in an early version. The in-game font for the E3 build was based off the ''[[Mario Kart: Double Dash!!]]'' in-game font, but was changed to the font used in the newer games on the final version.

(played in the minigame [[Speeding Bullets]]), while the song "Super-Duper Mario Bros." features the complete theme (played in [[Castle Clearout]] and [[Shell Soccer]]). Another arrangement of the Ground Theme plays in the Museum. The title theme features the Ground Theme's first six notes halfway through. The music in the minigame mode Choice Challenge is an arrangement of the [[Underground Theme]].

*''[[New Super Mario Bros. Wii]]'': Many of the environments and minigames in the game are based on the worlds of this game, including the background of the minigame [[Upward Mobility]]. The design of the [[Ice Flower]] of this game appears in [[King Boo's Puzzle Attack]]. Bowser Jr. appears in his [[Junior Clown Car]]. Also, some of the Bowser Jr. Minigame music is an arrangement of Bowser Jr.'s battle music in this game. Toad Houses also appear, in the same style as those in this game.
