Exact-hit bonus

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.

Rounds

With a round limit, the game ends after the last round and crowns an overall winner by wins.

How to play

  1. Pick a target range. Every round rolls a surprise target from your range — anywhere from 0.1s up to 3, 10 or 15 seconds, or a custom range you set yourself.
  2. Start the timer. The clock hides the moment it starts — count in your head. In solo practice you can also keep the clock visible.
  3. Stop when you think it's time. The display reveals your exact time and how far off you were.
  4. Closest player wins the round and gets 1 point — or 2 points for stopping exactly on the target, if the exact-hit bonus is on. After the final round, the player with the most points takes the game.

What Is the Guess the Time Game?

In Guess the Time, one player (the runner) starts a hidden timer and stops it whenever they want. Then every other player guesses how long the timer ran. The closest guess wins the round — not the runner.

It's a different test from the other modes: here you're estimating an unknown duration that already passed, rather than stopping a clock on a target you know in advance. The skill set overlaps — both require time perception — but the mental process is completely different.

Strategy for Guessing

As a guesser, anchor on rough multiples. If the runner seemed to press Stop fairly quickly, guess somewhere around 2–4 seconds. If they paused a long time, 8–15 seconds. Watch the runner's face and body language — most people exhale or relax slightly when they press Stop.

As the runner, try to hold a specific target in your head. Pick a number before pressing Start, aim for it, and then see how close the guessers can get. This gives the game structure and creates a reference you can reveal after everyone's guessed.

Guess the Time FAQ

How many players can play Guess the Time?

2 to 12 players on one device. One player is the runner each round; everyone else guesses. Roles rotate so everyone gets a turn running the clock.

What if two guessers tie?

If two players guess the same distance from the actual time, the round is a draw and both earn 1 point.
