'''Game Guy's Sweet Surprise''' is a Game Guy [[minigame]] in ''[[Mario Party 3]]''.

==Overview==
The player guesses whether the [[Big Chain Chomp|Big Chomp]] or [[Chain Chomp#Mario Party 3|Little Chomp]] finishes their [[cake]] first. The player can read of each [[Chain Chomp]]'s mood before choosing one of them. If Big Chomp is the correct answer and the player selects it as their guess, their total number of [[coin]]s is doubled. If Little Chomp is the correct answer and their guess, the player's coin total multiplies by 4, 8, 16, 32, or 64. If the player makes a wrong choice, they lose all of their coins.

===Mechanics===
[[File:MP3 GGSS Small Chain Chomp victory.png|thumb|The rare occurrence of the Little Chomp winning.]]
At the beginning of the minigame, the Big Chomp is always assigned a multiplier of ×2, while the Little Chomp is equally likely to be assigned a multiplier of ×4, ×8, ×16, ×32, or ×64. The probability that the Little Chomp will finish its cake first depends entirely on the multiplier assigned to it. The moods of both Chain Chomps do not affect their likelihood of winning.<ref name=jengerer1>{{cite|author=Jengerer|date=February 20, 2020|deadlink=y|archive=web.archive.org/web/20220315133129/https://www.jengerer.com/big-chomp-and-little-chomp|title=Big Chomp and Little Chomp|publisher=Wordpress|accessdate=March 7, 2025}}</ref>

At a fixed interval, one of the two Chain Chomps takes a bite of the cake. Below are the probabilities of either Chain Chomp taking a bite of its cake during an interval, based on the multiplier assigned to the Little Chomp:
{| class="wikitable"
|-
! Multiplier !! Chance [[File:Big Chomp MP3.png|44px]] takes a bite !! Chance [[File:Little Chomp MP3.png|44px]] takes a bite
|-
| ×4 || 50% || 50%
|-
| ×8 || 60% || 40%
|-
| ×16 || 70% || 30%
|-
| ×32 || 80% || 20%
|-
| ×64 || 90% || 10%
|}

During the same interval, the Chain Chomp that took a bite has a 40% chance to take a second bite. The first Chomp to take six or more bites wins.<ref name=jengerer1/> This means that the overall probabilities that either Chain Chomp will finish its cake first are as follows, based on the multiplier assigned to the Little Chomp:<ref>{{cite|deadlink=y|date=February 24, 2020|archive=web.archive.org/web/20220315133124/http://www.jengerer.com/meet-the-chomps-part-ii|title=Meet The Chomps: Part II|publisher=Wordpress|accessdate=March 7, 2025}}</ref>

===Expected value===
Let ''B'' be the number of coins bet. The following table shows the EV for each multiplier assigned to the Little Chomp, as well as whether the player bets on the Big Chomp or the Little Chomp.

{| class="wikitable"
|-
! Multiplier !! Bet on [[File:Big Chomp MP3.png|44px]] !! Bet on [[File:Little Chomp MP3.png|44px]] !! Higher EV
|-
| ×4 || 2''B'' × 0.50000 = '''1''B''''' || 4''B'' × 0.50000 = '''2''B''''' || [[File:Little Chomp MP3.png|44px]]
|-
| ×8 || 2''B'' × 0.70927 ≈ '''1.419''B''''' || 8''B'' × 0.29073 ≈ '''2.326''B''''' || [[File:Little Chomp MP3.png|44px]]
|-
| ×16 || 2''B'' × 0.87201 ≈ '''1.744''B''''' || 16''B'' × 0.12799 ≈ '''2.048''B''''' || [[File:Little Chomp MP3.png|44px]]
|-
| ×32 || 2''B'' × 0.96460 ≈ '''1.929''B''''' || 32''B'' × 0.03540 ≈ '''1.133''B''''' || [[File:Big Chomp MP3.png|44px]]
|-
| ×64 || 2''B'' × 0.99654 ≈ '''1.993''B''''' || 64''B'' × 0.00346 ≈ '''0.221''B''''' || [[File:Big Chomp MP3.png|44px]]
|}

If the Little Chomp has a multiplier of ×4 and the player wishes to earn as many coins as possible, they should always bet on the Little Chomp, as it has the same chance of winning as the Big Chomp but double the expected value. At ×8 and ×16, the Big Chomp is much more likely to win a single round, but the Little Chomp has a higher reward in the long run. At ×32 and ×64, the Big Chomp's win rate and expected value are both higher than the Little Chomp's; betting on the Big Chomp in those cases is nearly guaranteed to result in the player doubling their coins.
