As a kid, I enjoyed playing the original game. The advantage of the digital version of Labyrinth is that you can test your skill on multiple maze designs, whereas when you play the wood-and-marble game, the only way to get a new labyrinth is to buy a new box. The Labyrinth app gives you thousands of levels to play.
Better yet, you can go to the and design your own levels. The editor is highly intuitive and easy to use.
When properly calibrated, the controls for Labyrinth work perfectly. If the tilting controls for your phone seem off, you can recalibrate them from the settings. There's also an option for '3D mode', which creates the illusion of depth around the walls as you tilt your phone. Labyrinth is a beautifully designed app, and a game you'll have trouble putting down.
