SpeedTester is a simple, free game from the Ovi Store that tests rapid responses and thumb-eye coordination. You have four lights which will light up one at a time. All you have to do is touch the one that is lit. This occurs very slowly at first, and as your points rises, so does the speed.
It gets sufficiently faster after 100, before that, it’s nice and slow to get you accustomed. Each time you fail, you start back at the extremely slow stage.
Here’s a demo video of SpeedTester, shown on the Nokia N97
