I'm confused if this is a puzzle game, or a memory game by classification. I guess it's really considered a match up game. You see, the purpose here is to match all the cartoon or animated heroes on tiles; like Mahjong except that their not stacked together, but all against eachother on one layer. The trick is that there has to be a path between them, unless their pressing against one another of course, but otherwise, you have to have a path to the pairs or they can't be made. It's actually quite fun, I just glanced at it out of curiousity, and I'm STILL playing it.
