With the bonus on, stopping the clock exactly on the target (to the hundredth, like 5.00) makes the round worth 2 points instead of 1.
With a round limit, the game ends after the last round and crowns an overall winner by wins.

No account needed. Create a challenge and send the link — everyone who joins shows up in your player list, and you press Start when they’re all in. Then you take turns on the same target, exactly like pass-and-play: closest stop takes the round (+1), an exact hit is worth 2 points, most points wins.

The time stop game gives you one job: see a target number of seconds, start a hidden clock, and press stop the moment you think those seconds have passed. No moving dial, no ticking sound, no visual clue — just your own internal clock running against a real timer. The display reveals your exact time, your margin of error, and a verdict. Then you do it again.
It goes by a few names — time stopper game, time stop challenge, time pause game — but the mechanic is always the same: a hidden clock, a target, and one press to stop time as close as you can. On this page, your target is drawn randomly each round from a range you choose, so no two rounds are the same.
Press Start and the display shows your time counting. In multiplayer, the clock goes dark immediately and stays dark until you press Stop. In solo practice, you can keep the clock visible for a few seconds before it hides, which is useful for getting your counting tempo right before attempting blind rounds.
After you stop, you see your exact time to the hundredth of a second and your delta — how many milliseconds early or late you were. A negative delta means you stopped early; a positive one means you ran over. Most people are surprised to find they have a consistent bias that shows up round after round.
Count with long syllables. "One-Mississippi, two-Mississippi" is the old standard for a reason. Any counting method that speeds up under pressure will hurt you — long syllables are more resistant to rushing.
Start your count before the display goes dark. If you wait until the clock hides to start counting, you've already lost a fraction of a second. The count and the press should start at the same moment.
Track your bias over several rounds. After five rounds, look at whether your errors are mostly early or mostly late. If you consistently stop early, train yourself to wait one extra beat. If you run over consistently, trim your counting pace slightly.
Use anchors for longer targets. For a 10-second target, count to five and pause briefly to confirm you're at the halfway mark, then count the second five. Chunking a longer target into two halves cuts compounding error.
The game measures your distance from the target:
In multiplayer, the player closest to the target wins the round and earns 1 point. Stop exactly on the target — 10.00 on a 10-second round — and that exact hit is worth 2 points with the bonus on. After the agreed number of rounds, the most points wins.
No. A reaction test measures how fast you respond to a signal. The time stop game measures time estimation — how well you can feel a fixed number of seconds pass with no clock to watch. The skills are different, and reaction speed barely helps you here.
Under any kind of pressure or excitement, people tend to count faster than normal without realising it. Slowing your syllable count deliberately and taking a breath before pressing usually fixes an early bias. Also try playing a few rounds with the clock visible to calibrate your pace.
Yes. Most people who play regularly find their average error drops significantly in the first few hours of play, mostly by identifying and correcting their direction of bias. A consistent counting technique helps lock in the gains. See Can You Improve Your Sense of Time With Practice?
