Your goal in Key and Key is to build a key to fit a musical lock.

Click the lock pins, and try to match the sound they make by dragging musical notes up and down the music staff.

Only the blue piano keys are valid possibilities!

When you think you've got it, click the key to the right of the lock to try it. If it gives you a check mark, you win!
