Welcome to the new online game C21A. In it you will play cards. In front of you on the screen you will see a cat sitting in the center of the room. The number 21 will appear above the cat. Your task is to bring it to zero. You will do this in a fairly simple way. Cards with numbers will appear on the panel under the cat. By selecting them with a mouse click, you can move them and put them in the paws of the cats. This way you will subtract the numbers shown on the cards from the number. As soon as you get the number zero, the level will be completed and you will receive a certain number of points for this in the C21A game.
