Tap Low by Technossion FREE

Tap Low comes from Technossion. It's a 'think-fast' game.  The object is to tap on the lowest number within 3 seconds.  Keep doing it.

Obviously this game doesn't have much repeated fun value.  But it's worth playing a few times to keep the brain sharp.

The program is a bit clunky; a few times I had to repeatedly tap the lowest number for it to register.
