Find the beat of your internal clock.
Round 1 of 5
Target: 3.6 s
Ready when you are.
Find the beat of your internal clock.
Start the clock, then stop when you think the target time has passed. No visible countdown. An exact stop earns 100 points; two seconds away earns zero. Switching tabs cancels the attempt.
Each game has five daily rounds worth up to 100 points each (500 in total). The rounds change at midnight on your device’s local calendar date, so players in different time zones can be on different days. Your daily result is stored only in this browser. Practice mode gives a new set of rounds whenever you like and does not affect the daily result.
No. The games are free and run in a web browser on desktop or mobile, with no sign-up or download. Scoring happens on your device. Sound is off until you turn it on.
