User can pick a card layout of either 2, 4 or 8 cards. Each card is facing down. When card is clicked it turns around revealing a random number (1-2, 1-4 or 1-8 depending on a layout). Picked number cannot be picked again, unless that card is flipped over. Cards that are not revealed can be shuffled. Card colors and numbers are not bound to each other.
