Two players take turns placing cards on a three-by-three grid.
When it is your turn, you must place a card on one of the open spaces on the grid.
When a card is placed, the numbers representing its four sides are compared to any adjacent cards. If a number on the card placed is greater than the number it faces on an adjacent card, you will flip that card and capture it.
The objective is to capture and control more cards than your opponent.
