I've heard from a very reliable source,
If you take the pain on your legs from sitting and playing Aces High nonstop, multiply that by 6, and subtract by 3, you will get the number of hours you have been playing.
Now, take in account all the leg pains in the world at any given night, and divide that by 1. The quotient will give you a very accurate number for the amount of people playing Aces High at the time.
