Charm Tale

The Good
It is surprisingly addictive despite being not exactly hard - for adults. It is rather relaxing to play a few levels in between work or reading. You can put a lot of perfectionism into dissolving the pattern efficiently, but you can also use more of a brute force approach (then the game will probably get boring). I actually liked the (repetitive) music. Matching the stones to the patterns may improve spatial/geometrical perception/understanding and there is no violence or anything offensive in game, so IF you want to let your kids play on the computer, this is a game I can recommend.

The Bad
For 20$ it is a bit short for my taste (about 50 to 60 levels IIRC?) The plot/story as well as the artwork and it's themes are quite cheesy. Probably okay or even interesting for children. Sometimes you will not pick the stone from the line you wanted and this can result in loosing valuable stones - annoying. There isn't much variation in the patterns, mostly they just get bigger (and thus the levels longer) and partly have 3 layers. You tend to end up with removing many single tiles towards the end - lots of clicking, annoying. You collect a bonus ability per level and if you focus on the right bonuses even the 'hard' setting becomes really easy quickly. You collect points for using bigger stones, but ultimately collecting points in this game (as in many others) is pointless.

The Bottom Line
It's a puzzle game where you have to remove a given pattern consisting of drop-like tiles by using random one- or multi-tile "stones" that travel along a line. If stones reach the end of the line, you lose, if you remove the pattern, you move on to the next level. In "no lose" mode, stones reaching the end of the line just disappear.
