Turn the timer on to compete with other players, or off to relax, whichever suits your mood. Let auto-note do the busywork for you, or leave it off for a bigger challenge. Be sure to try all three puzzle themes!

• 1 million puzzles, five levels. All Free!
• Three different puzzle themes
• Tracks your averages, records, and more
