The aim of the game is to eat the opponent's eater. The eater move alternately. Each eater has at most 4 possibilities to move (to the left, right, top and bottom). An eater can jump over an empty field, after that this field (if not marked yet) and the field where the eater came from will be marked with the color of that eater. It is not possible to jump over a field if it is marked with the opponent's color, but the field can be occupied by the eater. An eater can and must jump over two fields, if they both are marked with the own color. An Eater must always make a move with the highest value. The value for every field that will be marked is one. When an eater moves on a field which is marked with the opponent's color, the value is also one. So if an eater comes from an empty field and jumps over an empty field on a field with the opponent's color, the value of this move is 3. The highest value has the move by which an eater eats the other eater. If both eaters are on the game board after 108 moves, it's a draw.
