Skeleton key is a strategy game where players try to open treasure chests by shifting chest keys around in under a certain number of moves. All keys move at the same time, keys cannot be moved up and you must move around walls and other obstacles. As you progress, the levels get harder, you are given more keys and more objects to block your path.

You control the keys by flicking the screen in the direction you want them to move. A lot of the time, you will get stuck or run out of moves, in which case you shake the screen to reset the level. Since all keys move at once, you must move keys up to walls in order to shift them closer together to pass a narrow entry way.

The visuals are simple and clear, presenting players with a path. The sound is islandy and fun and changes across different levels to spice up gameplay. Players also have the option to use their iPod music, but must turn the game sound off manually or have the two tracks playing at once. This is a single player game, but players can upload highscores to the games leaderboards.

Skeleton Key is a great puzzle game where players must think before every move. The simple controls and gameplay leave players free to concentrate on the puzzles at hand and with 100 levels and 3 difficulties; players will definitely have a challenge unlocking all the treasure chests. Overall, this game is a must have if you enjoy puzzle games, but even if you’re not mad about puzzle games, try it and see what treasures you can uncover.
