There is a field - 6x6 cells. Each field can be empty or contain a colored brick with arrow on it. Arrow direction depends on the bricks color (or vice-versa). You can manipulate these bricks: tap on the brick to move it accordingly to it's arrow direction. Groups of two or more bricks having the same color dissapear, but each turn some new bricks come to the field. Destroy bricks to earn points. The goal is to earn as much points as you can. The game ends when there are no empty cells left on the field so it's impossible to place incoming bricks on it. |
