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.

The stopwatch challenge is a timing game where you start a hidden stopwatch and stop it as close to a target time as possible. The clock goes dark the instant you press Start — no ticking, no dial, no visual cue. You count in your head, hold your pace, and press Stop when you believe the target time has passed. Then the stopwatch reveals your exact time.
It's the same core test as the rest of the timer games on this site — but framed around a classic stopwatch. If you've ever used a physical stopwatch in a PE class or timed an experiment, this is the digital, blind version of the same challenge.
Count with a consistent method. "One-one-thousand, two-one-thousand" gives each second roughly the same length. Counting bare numbers tends to speed up after a few seconds, which means you'll stop early on longer targets.
Match your counting pace to the clock before it goes dark. In practice mode, watch the clock for the first second or two, then let it hide. Use that visible time to calibrate your mental count.
Know your bias. After five rounds, check whether you're early or late on average. Most people have a direction — if you're consistently 0.3 seconds early, try adding a half-beat at the end of your count.
Hesitating after you decide. The gap between thinking "now" and actually pressing can be 0.1–0.2 seconds. Once you decide it's time, press immediately — don't second-guess.
Counting too many syllables. Long words like "one-one-thousand" work, but some people add extra syllables under pressure. Count slowly but steadily; speed is the enemy.
Overthinking during the round. Trying to recalibrate mid-count usually makes things worse. Commit to your opening pace and follow it through.
Your result is judged by how close you stopped to the target:
In multiplayer, the player closest to the target takes the round (+1 point). An exact match — stopping the stopwatch at precisely the target — earns 2 points when the exact-hit bonus is on. Play 3, 5 or 7 rounds and the most-points player wins.

The stopwatch challenge uses a random target drawn from your chosen range, so you never know in advance what time you're aiming for. The 10-second challenge always targets 10.00 seconds, which lets you develop a specific technique for that exact duration.
