### 5/5 — 중독성있는 게임

애들도 좋아하고 12x12는 정말 어려워요.

### 5/5 — A great little math game!

*2013-01-15*

A nice little game that can be fairly easy on the 6x6 grid, and gets progressively more difficult. I like that it's very easy to change your choice; just tap an area you've built and it goes away.

The help could give more suggestions on how to learn to play this game, and it might be nice if there were a hint option during game play, but otherwise the game is great!
