Every round rolls a fresh random target inside this range.
More options — mode, bonus, rounds ↓
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.

Every round, the game rolls a fresh random target time within your chosen range. You don't know if it's going to be 3.4 seconds or 8.1 seconds until after you've stopped — which means you can't memorise a fixed technique and repeat it. Your raw time sense is all you have.
This is the most honest test of time perception on the site. The fixed-target challenges let you build a calibrated routine for one specific duration. The random challenge strips that away and measures how well you adapt.
Count continuously and trust the count. You don't know the target, so start counting from the moment you press Start and stop when your count reaches the number you're aiming for. If your range is 5–10 seconds, count at your usual pace and stop when the count feels right relative to the target shown.
Read the target number clearly before pressing Start. Sounds obvious, but a lot of early errors come from misreading the target — especially when it's a decimal like 7.3 — and stopping at a round number instead.
Don't anchor to your last result. Each round is independent. If you ran over by 0.8 seconds last round, resist the temptation to stop early this round to compensate. Reset and count fresh.
The verdict thresholds are the same as all other modes: PERFECT within 0.05s, SO CLOSE within 0.20s, NOT BAD within 0.50s, WAY OFF beyond that. Random targets make consistent PERFECTs very hard, but consistent SO CLOSEs show excellent time perception. Compare with your friends using pass-and-play or Challenge a Friend.
Start with the default Surprise 10 range (up to 10 seconds). Once you can consistently hit SO CLOSE on that, try a wider range or a longer maximum. The custom range option lets you go up to 120 seconds for extreme endurance rounds.
Yes. The target is drawn from a random distribution within your chosen range each round, to the hundredth of a second. You cannot predict it.
