Rules

In four rounds of rolling 5 dice, can you roll as close to or equal to 20 without going over?

  • After each round, you may save as many dice as you like and not re-roll those dice for the rest of the remaining rounds.
  • For your second and third round, roll the dice you haven’t saved.
  • For the fourth and final round, roll any remaining unsaved dice
  • If your five dice form a sum greater than 20, you score 0. If the sum is 20 or less, that sum is your score for the turn. Decide on how many turns each player will get at the start of the game. The winner is whoever has the greatest score at the end of the game.

Save Twenty can be played individually or in groups.
