Welcome to our cozy home, where the fireplace is burning, and cute cats are sitting on soft pillows in front of it, which you will feed in C21A. At first you have to feed one cat, but then the rest will appear. A variety of food with numeric symbols will appear on the panel below. Cats also have numbers, and initially they are twenty-one. Transfer food to the selected cat, add up the numbers and get the result. You have to hit zero to get back to 21. Going below zero is not allowed, otherwise the C21A game will end.
