Baboo: Rainbow Puzzle

Baboo wants to play. He has prepared an insteresting game for you, which seemingly recalls the already legendary Tetris game. You task is to place cubes in various formations on the board so that you can create a row of the cubes, which are all the same. The row then disappears and you have more room to place even more cubes. But be careful, do not place individual clusters so you will not be able to place further ones. You would have to start from scratch again. Have fun.
