Reflex Speed is a short, sharp reflex game. A shape appears on the screen — tap it as fast as you can before it vanishes. The timer starts slow and speeds up every few rounds, until the shapes are flying by. One miss and the round is over.
Your reaction time for each round is measured in milliseconds, and a clean scoreboard keeps track of your best runs. Daily rounds come in three difficulty settings: relaxed, normal and intense. Beat your own record, then try to beat it again tomorrow.
