"Crossover 21" Game

Crossover 21 is a hybrid of several puzzles that will make your brain work hard. Your task will be to collect a combination of cards that will yield 21 points horizontally and vertically. On each round the player gets three sets of cards, from one to several cards each. You need to place these cards on the field to get 21. If a combination of cards yields more points when you fold, the cards are blocked (marked with a red cross) until you put together a winning combination. If you manage to put together a combination of cards that yields 21 points, the cards disappear from the field. Bonuses can be used to unlock cards: a joker, which yields 21 in the row in which it is placed; a hammer, which removes a card from the field; and a cross, which removes all crosses from the field. The game has several levels, the difficulty of which gradually increases.
