Crazy 21

Crazy 21 is a single-player card game. Each card goes into one of five columns. When a column adds up to exactly 21, it is cleared and you score points. If a column goes over 21, the game ends.

How to play
Tap a column to place the current card. The next card is also shown, so you can plan your moves. Aces count as 1 or 11; J, Q and K count as 10. A column with five cards that stays under 21 is also cleared. Every column you clear raises the score multiplier, up to x5.

Daily challenge
Each day there is one deck, the same for all players, and you get one attempt.

Leaderboards
You can compare your scores with other players on the online leaderboards.

Once per game you can swap the current card, and once you can continue after going over 21, by watching a short video.

The game can be played offline. Leaderboards and videos need an internet connection.
