There is a field - 6x6 cells. Each field can be vacuous or hold a coloured brick with arrow on it. Arrow direction depends on the bricks colour (or vice-versa). You can control these bricks: dog on the brick to go it accordingly to it's arrow direction. Groups of two or more bricks having the same colour dissapear, but each twist some fresh bricks amount to the field. Destroy bricks to gain points. The goal is to gain as much points as you can. The game ends when there are no vacuous cells left on the field so it's impossible to site incoming bricks on it.
You tin manipulate dyed bricks with arrows on them. When you tick on the brick it moves accordingly to it's arrow direction. Groups of two or more bricks having the same color is dissapearing, but each grow some unexampled bricks comes to the field.
