🕹️ How to play

How to play the 10 second challenge: Tap Start on the big dial. The numbers disappear straight away, so count to ten in your head and tap Stop. You first see whether you were early or late and by how much, then your real time and tier. Tap the dial again for another go.
How to play with friends on one phone: Switch to Take turns, enter 2–8 names (shuffle the order if you like) and press Start. Each time is sealed as soon as the player stops; they can peek and hide it, then pass the phone. When everyone is done, the ranking is revealed from last place up.
How to change the target or turn on no going over: Open More rules to pick a 5, 10 or 20 second target, or switch on No going over, where any stop past the target is a bust. Solo players can also use Warm-up to practise with the numbers visible; warm-up stops are not recorded.

📖 Rules & variants

Scoring: the time from pressing Start to pressing Stop is rounded to the nearest 0.01 s, and the number you see is exactly the number that is judged. Only 10.00 counts as a bullseye; 10.01 is late by 0.01 s.

Accuracy tiers: exactly on target is Perfect 10; within 0.05 s is Hair's breadth; within 0.10 s Nearly there; within 0.30 s Pretty close; within 1.00 s Clock drifted; anything further is Lost in time. The 5 and 20 second targets use the same table.

Why the timer is hidden: while it runs there is no readout and no moving animation you could use as a metronome. Only solo Warm-up shows live numbers, and warm-up stops never count.

No going over: when it is on, stopping even 0.01 s past the target is a bust and never becomes your best. In a group, everyone who did not bust ranks ahead of everyone who did.

Forgot to stop? The round ends by itself at three times the target (30 s for a 10 s target) and is marked Lost in time with a 'Fell asleep?' note. It is left out of your early/late trend.

Leaving the page: switching apps, locking the screen or taking a call while the timer runs voids that try. In a group the same player goes again and the ranking shows 'Redo ×N'. A second press within 0.4 s of Start is ignored so a double tap cannot stop the clock.

Ranking and tiebreaks: players rank by how far they were from the target, equal gaps share a rank. A shared first place can play one tiebreak stop each; in the next round the last-placed player goes first.

Counting tips: split ten seconds into two counts of five, or count 'one-Mississippi' to slow your pace. Check the trend line on your result card — if you keep stopping early, wait half a beat longer next time. Nerves make most people count faster.

❓ FAQ

How do you do the 10 second challenge without looking?

You count in your head: once you press start the numbers are hidden, and you stop when you think ten seconds have passed. Counting 'one-Mississippi' or splitting it into two sets of five keeps your pace steady.

What counts as a good score in the stop at 10 seconds game?

Anything within 0.05 seconds of 10.00 is excellent, and within 0.30 seconds is a solid result most people reach after a few tries. Only an exact 10.00 counts as a bullseye here.

Why do I always stop the timer too early?

Most people count faster than real seconds, especially when they are nervous or being watched. Slow your count with 'one-thousand-one' style beats and follow the trend hint on your result card to correct it.

How do you play the 10 second challenge with a group?

Use Take turns mode: 2–8 players pass one phone, each time is sealed so the next player cannot see it, and the ranking is revealed together at the end. The last-placed player goes first in the rematch.

Is the 10 second timer game fair on phone and computer?

It is fairest when everyone plays on the same device, because touch and key latency differ slightly between devices. The timer starts and stops the instant your finger or key goes down, and Space works on a keyboard.

Can I practise for the 10 second stopwatch challenge in restaurants here?

Yes, the idea is the same — stop a hidden timer at exactly 10.00. Real challenge machines use their own hardware and rules, so treat your score here as practice only; there are no prizes on this page.
