With our free online Bumper Cards, the game deals from a deck of cards one at a time. It's fairly straightforward in that a card can be placed on one of four stacks or thrown away by clicking on the discard pile (subtract 5 points). The value of each stack is added. Numbers are worth their written value, so face cards are worth ten, and aces can be either 1 or 11. Points awarded for each stack are as follows: If you get 21 with 3 cards: 120 If you get 21 with 4 cards: 140 If you get 21 with 5 cards: 160 If you get 21 with 2 cards: 180 If your stack has 5 cards but is worth less than 21: 200 If your stack of cards is worth 21 with a black jack and an ace: 250 If your stack is worth 21 with three 7s: 300 If your stack is worth more than 21: -50 (Bust) Here are how multipliers work: The points for any stack are multiplied if you close, or score 21, in a row. Keyboard commands: For our free, online Bumper Cards, the left and right arrows will help you move from stack to stack, the down arrow drops your card on a stack, and then the up arrow discards it.
