In the default variant, the board shows 12 faces in four colors, with three of same color. You can either slide a face all the way toward another face in the same column or row, or you can jump over an orthogonally adjacent face, landing on an empty position.
You cannot slide a face toward a wall or toward the border.
Beginners You must end up in a configuration where the faces of one color are a connected group, and this must be true for each color.
The faces that have neighbors of the same color will smile. If there are three faces or fewer per color, then making all faces smile will win the game.
