Crossover 21

Will you be able to master this innovative version of Blackjack? Find out if you can get all of the cards to match up in Crossover 21

Take a look at the board and carefully consider where to put every card. You’ll need to make each row and column add up to 21. Useful boosters will help clear space while you play Crossover 21, which has become one of our most popular free games of 2019. If you find yourself in a jam, just break out a hammer or a joker booster. 

Looking for even more clever and challenging card games? Try Secret Double Klondike and Solitaire FRVR.

Game Controls

  • USE THE MOUSE to choose cards and boosters.
  • LEFT CLICK to use them on the board.
