I found a very nice game called HEXIOM by Turbogames
The goal is to place all tiles in such a way, that the number of neighbour-tiles equals to the number on the tile itself. For example, a tile with a big 2 on it, should have only 2 neighbouring tiles.
Try Hexiom yourself. And if you had enough, than go play Hexxagon or Attaxx 🙂
