The game proceeds clockwise, starting with the first player selected at random. On your turn, you must place a tile on the grid, either face down or face up. If it is impossible to do this, skip your turn.

The tile you place must be adjacent, both orthogonally and diagonally, to another tile and must conform to the construction of a 4x4 square (in a 2 player game) or a 5x5 square (in a 3 or 4 player game). players). When you place a tile face up, you draw 2 tiles from your stack. Face up tiles can always be covered with face down tiles, whether they are yours or not.

The tile you place must cover another tile and "beat" it, according to the traditional rules of Rock, Paper, Scissors. When you place a tile face down, you do not draw tiles at the end of your turn. A face-down tile cannot be re-covered.

Passing is only allowed if you run out of tiles or if you cannot play. Then draw 2 new tiles.
