Though addictive and fun to play at first, this game will become boring eventually.

Polarium will probably start off interesting and addicting to anyone who picks it up, but it quickly gets boring and needs more work. It's technically tetris with a different style, only there are a couple of modes added on. The concept is simple, you have to flip tiles to either black or white until a whole row is the same colour.
There are two different modes you'll want to focus on, Challenge and puzzle. Challenge mode is the aspect of the game that acts like tetris, in which you have to try and clear rows to keep going. Although it's fun to start off with, it lacks depth.
The most interesting and somewhat slightly harder mode of Polarium is puzzle mode. In this you have to clear every row in one go, and this can be both confusing and fun, so will keep you playing a lot more than Challenge mode. There are also 100 puzzles to get through, so it'll take up your time if you get stuck on them easily.
The graphics and sound may be poor, but it's not really an issue as the idea of the game is simple and you don't need to worry about this, although they would have been a nice extra. The game play will keep you interested for a while, and the game has one of the lowest values on a DS game, so if you really are into puzzle games, you should give this a try.
