Timekeeper

How to play

Remember the interval. Press Stop when that much time has passed after GO.

Controls

Tap Stop or press Space

A few ways to improve

• Use a steady internal beat and adapt it after the previous result. Keep the beat regular instead of counting faster when the target interval is longer.
• Use the preview to finish observing, then switch attention to the response. Keep your finger or pointer near the answer area without pressing early. If one challenge is lost, let it end and begin the next with a fresh plan instead of carrying a guessed answer forward.

Difficulty and daily progress

A round lasts 45 seconds. Every three starts of Timekeeper raise its daily difficulty, up to difficulty 10. Your count resets at 00:00 UTC, so tomorrow begins with the starting challenge again. The clock continues if you switch tabs, and leaving ends the attempt.

Scores and rewards

The score measures this game’s performance. Reward points are a separate account balance. Practice rounds earn no points or XP and do not enter the rewarded leaderboard. Rewarded rounds require sign-in, human verification, active play, and live gameplay checks before a result is saved. Idle or abandoned rounds do not earn rewards.

After an eligible rewarded round, keep its sponsored claim page focused for 12 seconds and complete a fresh hCaptcha. Then select Claim reward to add the pending points and XP to your account. No advertisement click or purchase is needed. You can return to an unfinished claim from the arcade; another rewarded round becomes available after that claim is collected or skipped.

Account points currently unlock site cosmetics. Each player level after level 1 adds a 0.1% bonus to points earned from games. Read the fair-play rules or visit Support if a round needs help.
