Don't Bust 100

Don't Bust 100 is a classic card game of ups and downs for 2+ players ages 8+, and takes about 20 minutes to play.
Math has never been more fun! Players strategically play their cards one at a time and add up the value of the main pile as they go. The total value must not exceed 100; otherwise, you BUST and lose a token. The cards are then reshuffled, and the game begins anew. The last player with tokens left is the winner. Strategic use of specialty cards keeps this game challenging.
