The board is made up of a 7x8 grid, and therefore 56 cells. Each cell has directions painted on it: these are the directions any piece is allowed to follow when starting from that cell. Only the starting cell directions have to be obeyed. You can not change direction during your move.
There are 3 types of pieces. Each opponent starts with 1 Brain, 4 Numskulls and 7 NinnysNinny moves one square in one of the allowed directions
Numskull moves any number of squares in one of the allowed directions
Brain moves one square in one of the allowed directions
How to play.
Each player moves one piece per turn.
To win you need to capture your opponent's Brain.
To capture a piece just go onto its square.
Capture is not obligatory.
A Ninny reaching an opponent's Numskull starting position promotes to a Numskull.
If only the 2 Brains remain on the board, it is a draw.
