Perfect Timer Challenge
Stop the clock as close as you can to the target. Pure internal timing - no counting on screen.
Test your internal sense of timing - a random target time between 0 and 20 seconds is set, and you must start and stop a hidden timer as close to that exact target as possible. With multiple modes and difficulty levels, it's a genuinely tricky test of timing intuition rather than reaction speed.
Frequently asked questions
Hiding the running timer forces you to rely purely on your internal sense of time passing, rather than reacting to numbers on screen - this is the core skill the game is designed to test and help you improve.
Difficulty controls how close to the exact target time you need to stop to count as a win - easier levels give you more tolerance (margin of error), while harder levels demand near-perfect precision.
