Reaction Speed Test

Click the button in the center of the screen while it is red to start the wait timer. The button will then turn yellow for a random delay based upon the time seed, if you click the button while it is yellow a penalty will be added to your score. When the delay ends the button will turn green, click it as fast as you can. You may use the space bar instead of clicking.

When you click the reset button it will reset all statistics and set the random delay seed to whatever is in the text box below it.
