The goal of each level is to connect all of the runes using the least amount of magical energy without--as the name of the game makes clear--lifting your finger. The puzzles are simple at first but become increasingly difficult to 3-star at higher levels. But don't worry, even if you can't 3-star every level, you can still advance in the game and enjoy the relaxing music and sounds. And that's what makes it a Zen game!
