Blocks originally placed on the field of fixed and marked point.

Each exhibited on the new unit has a direction of movement indicated by the arrow, and if it does not hold, then it starts to move in this direction as long as no other will face block or not go beyond the edge of the playing field.

If three or more blocks of the same color are connected together at the sides (not diagonally), then they are reduced.

Your task is remove all blocks from the board.
