Here is Domina 4. Be careful. It may cause a headache!

What you need to play Domina 4:

- 25 square tiles in 5 colours (5 each).
- 5 black pawns.
- 5 white pawns.

Randomly configure a 5x5 board using the 25 coloured tiles so that no 2 tiles of the same colour are orthogonally connected. You can draw a board if you don't have tiles.

Placing phase: White starts. Players in turn place ONE of their pawns in any empty square of the board until all the pawns have been placed.

Moving phase: White starts. Players in turn MUST move ONE of their pawns 1 square up, down, left or right to an empty square.

The game ends when one of the players ‘dominates’ the board by having placed 4 of its pawns in 4 equally coloured squares.
