Invisible

Each game turn is broken down into 2 phases.

First phase, movement: from 0 to 3 squares in all directions without going through the destroyed squares.

Second phase, shooting: only in a straight line and as many boxes as you want. If the target square is empty, it is destroyed.

A destroyed square can no longer be used, neither for movement nor for shooting.

A player wins if he destroys or blocks his opponent.
