Watch the hammer move from side to side, then tap at the right moment!
Aim near the center of the nail and drive it home in one hit.
Each successful hit takes you to the next stage. From Stage 5, the speed doubles. Miss the nail and you start again from Stage 1!
Meet an expressive hammer in a simple timing game with handwritten-style lettering, comic-style effects, metallic hit sounds, and a rhythmic drum beat.
- Simple one-tap controls
- Advance with every successful hit
- Double speed from Stage 5
- Switch the background music on or off
- Japanese and English support
