The uninitiated's guide to mastering the art of tenkey.
Tenkey is a highly addictive, moderately frustrating, and mildly rewarding puzzle game where you press a button ten times, then press the other button ten times. Repeat ad infinitum.
First, download the Tenkey client from the official site. Then, create a new account and log in. Don't forget to read the terms of service, but let's be real, who reads those?
Press the first button ten times, then press the second button ten times. Repeat this process ad nauseam, and you'll be well on your way to becoming a Tenkey Master.
