The goal is to be the player who has the most squares of their color.
The game uses pieces of six types, where each piece is in shape of a square. The sides of each piece are colored with one of red, yellow, green, blue, so that a piece has one side for each color. Each "side" appears as a triangle.
Each player on their turn puts a square next to a square already on the board. The piece may be rotated, but not reflected. The sides coinciding with previous pieces on the board must match in color.
It's possible for a blank square to be adjacent to two sides of the same color, blocking said square from being occupied (because there is no piece that has two sides of the same color).
When a player cannot put any piece, the turn is passed. In all other cases, the player must put some piece.
Due to the appearance of a side as a triangle, matched sides form a tilted square. Each of these squares scores a point for the person holding this color.
Ending the game
When no more piece can be put by any player, the player with the most squares of their color wins.
The colorblind option available for this game enables an alternative setup displaying symbols on the tokens using the great color code designed by Miguel Neiva: ColorADD.
Learning the code is easy, just take a look at the following synthesis panel:
