the mini game is kind of like the arcade game Bejewled. If you have 2+ of the same thing in a row (horizontal/vertical,) you can collapse it and whats on top will cascade downwards. The goal is the get rid of all the items on the screen which is almost impossable except for in the first level or so. once you begin to clear the items on screen, the mini-game gives you items (for example: potions, etc.) I havnt exactly figured out what items ill be offering via the mini-game, most likely game tokens of some kind that you can use in a specialty shop, or possibly a rare armor or weapon that you only get rarely via the last level or so.
