The game principle is likely to be well known. Another innovative feature is the division of the playing field in different tetris block-like structures that do not allow permutations over its defined boundaries. For this you can move and rotate. The music is the first few minutes of pleasant but invites latest after the fourth loop to unwind. For fans of the genre certainly a nice game, especially here not be sold like Candy Crush powerups. I was not really tied up and I have it erased.
