When you really want to tap, can you hold back?
Circles flash one at a time in the middle of the screen. If it's green, tap fast. If it's red, don't tap. Hold back! Your accuracy shows how well you can react quickly and still know when to stop.

How to play
- Tap Start. Circles will appear 14 times in all.
- When a circle appears, check its color.
- If it's green, tap it as fast as you can before it disappears.
- If it's red, don't tap. Just wait. When all the tries are done, you'll see your accuracy.
Tips
- Most circles are green (about 3 out of 4), so your finger easily jumps ahead on its own. Beating that habit is what this game is all about.
- If you don't tap a green circle in time, it counts as a miss. Being too careful will lower your score, too.
- Each circle stays on screen for 1 second. It's short, but there's enough time to check the color, so look at the color first.
