HOW TO PLAY This test is designed as a competition against your peers for the prized top slot on our leaderboard. You will be given 40 three-digit numbers that you must key in as fast as possible. There is no need to use your mouse during the game - just key in the numbers and hit "enter" on your number pad to move to the next number. To qualify for the leaderboard you must arrive at the proper total for all numbers entered, and your time must be in the top 20.
