Deserves better
The game has 4 different modes, each of which are unique. The general idea is to make rows of the same colour using stylus strokes.
Challenge
You have to clear rows of tiles to either black or white rows before the screens fill up. A bit like tetris.
Puzzles
This is where you will spend most of your time - you have to clear the board of black and white tiles (which are in a fixed shape) into rows of the same colour in one move. There are 100 puzzles, each increasingly difficult.
Versus
You'll need a friend for this one (Download play compatible). You turn your DSs onto the side and have to clear rows as usual, but once you do, it jumps over to your opponent's screen and the first person to get rid of them wins.
Edit
This is where you can design your own puzzles and send them to friends who have Polarium.
Overall this is a fun game if you are in the right mood and is easy to pick up. Puzzle game fans will love it, but this title wouldn't appeal to everyone.
