2 players start with a score of 100. Each turn, a player repeatedly rolls a die (click and hold A) until either a 1 is rolled or the player decides to "hold" (click and hold B) - if a player rolls a 1, they score nothing and it is the other player's turn; - for any other roll, the number gets added to their turn total and the player's turn continues; - if the player chooses to "hold", their turn total is taken away from their score, and it is the other player's turn. The first player to reach a score of 0 wins.
