'''Game Guy's Lucky 7''' is a Game Guy [[minigame]] in ''[[Mario Party 3]]''.

==Overview==
[[File:MP3 GGL7 higher roll.png|thumb|right|A rare example of the player's roll being higher than the total of Game Guy's rolls during the minigame]]
The player and [[Game Guy]] each roll a one-through-six [[Dice Block]] with the aim of going higher up a staircase with seven steps. If the player rolls a higher number, Game Guy loses, though he gives the player a chance to roll the Dice Block again and land on the top step, making it possible to earn double the [[Coin]]s but at the risk of losing all of their Coins if they roll a number higher than the steps remaining. The player wins if they land either on a higher step than Game Guy or on the same one as him. If the player ends on the seventh step, they receive ten times the number of Coins.

===Expected value===
Let ''B'' be the number of coins bet, ''P'' be the player's roll, and ''G'' be Game Guy's roll. There are four possible sets of outcomes, based on who rolls once or twice.

Due to the house losing ties, the player makes a long-term profit in all scenarios. While Game Guy's exact logic for deciding whether to roll again is unknown, whether he does or not matters little in terms of expected value. Naturally, the player rolling twice is a big boost to expected value, as the added chance of ×10 has a much bigger impact than the potential ×0, though if the player is merely trying to win, the second roll should be made only if necessary.

In addition, as the in-game limit of coins is 999, the expected value drops once the bet reaches 100 coins (as rolling a 7 results in only 999 instead of 1,000), and it drops further as more coins are bet.

==In-game text==
* '''Game Guy''' &ndash; ''"Hit the Dice Block, then climb up that many steps. You can hit the die once or twice. If you climb higher than me or stop on the same step as me, I'll double your coins! But if you stop below me, or if you fall off the stairway, I'll get to keep all of your coins. However! If you land exactly on the seventh step, your coins will increase tenfold!"''
