Imagine blackjack as a skill-based solitaire game, and you've imagined Catch-21. Speed through the deck as you make as many 21's as you can. And don't forget that black jacks are wild!
Your goal is to maximize your score by making 21's as fast as you can. Move the top card from the draw pile to one of the four columns. The number over the draw pile shows the number of cards remaining in the draw pile. You can move a card to any column provided that the resulting total of cards in the column is 21 or less. Face cards (Jacks, Queens, and Kings) have a value of 10; Aces can be either 1 or 11; other cards count their index value.
You can play Catch-21 for free, or for cash prizes against live players from all over the world in one-one-one games or in one of the many ongoing tournaments.
