Game Guy's Lucky 7

Game Guy's Lucky 7 is a Game Guy minigame found in Mario Party 3. Game Guy cites this minigame as his "personal favorite."

Gameplay
The object of the game is to get higher on the staircase than Game Guy by rolling a one-through-six Dice Block. After rolling once, both the player and Game Guy have the option to roll a second time. The staircase has only seven steps. If the player ends up on a lower step than Game Guy or overshoots the top of the stairs, they lose all of their coins. However, if the player lands on a higher step than or the same step as Game Guy, or he overshoots the top and the player does not, their coins are doubled. If the player manages to land exactly on the top step, their coin total is automatically multiplied by ten regardless of Game Guy's position.

If the player's first roll is higher than the combined total of Game Guy's rolls, he admits that he lost but then offers the player a chance to roll the Dice Block again and land on the top step. The player then has the option to agree or disagree. If they agree, they have the opportunity to earn more coins, but they risk losing them all. If they disagree, then they keep their current winnings.

Strategy
With Game Guy actively competing against the player, this minigame is more complex than the others.

Therefore, rolling again on 5 or 6 does not improve winnings.
 * If the player rolls a 1, they should always roll again (zero chance of going over).
 * If Game Guy is ahead of the player after both rolls, they should always roll again (not rolling again is a guaranteed loss).
 * If Game Guy has already lost (being tied, behind, or gone over) after both rolls, the player should not roll if they merely want to win. If they instead want to maximize expected value:

In-game text

 * Game Guy – "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!"
