About this game

NUM210 is a simple but fun number tapping game that'll test your mental dexterity to the limit. It's based on the number game that made Ayumu the Chimp famous, as he played the game faster than any human. You may have seen the video, it's sometimes known as the Chimp Challenge game.

Are you faster than a chimp? The numbers don't lie. Tap the numbers from highest to zero as quickly as you can.

Sounds easy? It's not...

In the early levels, you'll have plenty of time and we'll even highlight which tile to tap next. But the game gets tricky. As you progress, you'll encounter more devious challenges:

- The next tile won't be highlighted
- The grid will get bigger
- You'll be given less time
- Mistakes will put you back a step
- Numbers hide after some time
- You will be allowed fewer mistakes
- Then numbers will hide much faster
- Eventually you might get as good as a Ayumu the Chimp!

NUM210 is great brain training to help develop focus and mental reflexes.
