Crazy 4 is a card game for one person only. It remembers a little bit to a Patience game but it has a special set of cards consisting of numbers from 1 to 13 in four different colours. The exercises in the game will remind you playing Poker. The aim of the game is to fit together four cards, called the Crazy 4, from the rest of the cards, in the way that they can solve different exercises and satisfy criterions. Normally it is useful to have the right portion of luck but like playing Patience planning and thinking is also necessary to master the game. It differs from other games in the way that time is really important, that means, only who solves all exercises in time will reach a place in the highscore.
