Precision — 1v1 Reaction Time Duel

How to play Precision

1. 1Sign in, open the lobby and press Play to face a live opponent, or take a free practice match against the bot.
2. 2The server rolls a hidden target for the round, somewhere between 2.5 and 10 seconds.
3. 3A countdown runs, then both players' rockets launch at the same server-stamped instant.
4. 4Press STOP the moment you judge the target has been reached. You cannot see the target while the round is live.
5. 5The round is decided once both players have stopped. The closer stop takes the round.

Rules

• A match is best of five rounds: the first player to win three rounds takes it.
• The server rolls a fresh random target for every round, uniformly between 2.5 and 10.0 seconds.
• The target is kept server-side while the round is live and is only revealed when the round resolves.
• Both stops are server-stamped. The timing that decides a round is measured by the server, and a value supplied by a client is never the deciding number.
• A stop outside the permitted timing range is rejected rather than scored.
• Each round begins with a synchronized countdown so both players' clocks start from the same instant.

Scoring — what decides the winner

• The round goes to the player whose stop is closest to the target — the smaller difference between the elapsed time and the target wins.
• The first player to win three rounds takes the match.
• If a player never stops, the round is graded at zero elapsed, which is the worst possible score rather than a free pass.

Strategy and tips for Precision

• Count in your head rather than reading the timer. A steady internal count is far more repeatable than watching a fast-moving number.
• Aim slightly early. Most missed stops come from hesitating into a late click, and a small early stop is usually closer than a late one.
• Use a fixed rhythm and calibrate it. Because the target is random, your only real asset is a count you can reproduce within a couple of hundred milliseconds.
• Stay on the same physical setup. Your sense of time is affected by how you are sitting, how big the screen is and how you click, so consistency across rounds is worth more than any single trick.
• Commit on the count. The rounds that are lost are usually the ones where a player decided to stop after the moment had already passed.

What it tests

Precision tests time estimation and reaction consistency. The target is unknowable, so the game measures a physical skill rather than any knowledge of the rules.

Precision FAQ

Can I see the target before I stop?

No. The target is rolled server-side for each round and stays hidden while the round is live. It is revealed when the round resolves.

How many rounds is a match?

Best of five. The first player to win three rounds takes the match.

Is the target the same for both players?

Yes. One target is rolled per round and both players stop against it on the same server clock.

What if I never press stop?

The round is graded at zero elapsed, which is the maximum possible distance from any target — so it is the worst outcome available, not a safe one.

Is it free to play?

Yes. Nothing is wagered, and ranked results move your Elo and trophies for this game.
