Features

🤹Several timers count up at once, each with its own target. Stop each one as close to its target as you can — the twist is that they start at different moments, so you're always tracking more than one.
🙈From level 3 the displays go dark partway through, so you can't read the number — you have to feel the seconds and stop on your internal clock alone.
🎭Higher levels add decoy timers you must never stop; leave them to run out. Touch one and you lose a life, so it tests restraint as well as timing.
🧠It's a playful test of time estimation and divided attention — how well you can hold several intervals in your head at once, a skill studied in cognitive psychology.

Frequently Asked Questions

How do you play Chrono Juggler?

Each pot counts up in seconds toward a target you're shown. Hit STOP (or press its number key) as close to the target as you can — within 0.15s is perfect, and overshooting by more than 1.2s burns it. Clear every pot to advance; three burns or misses end the run.

Why do the timers go dark?

From level 3 the elapsed number hides after a couple of seconds, so you can't just read it off. You have to estimate the remaining time using your internal sense of duration. It's the core challenge — juggling several hidden countdowns at once.

What are the decoy timers?

Decoys look like normal pots but are marked 'don't stop'. You must leave them alone and let them run past their target — stopping one costs a life. They force you to hold back, so the game tests inhibition alongside timing precision.

What does this train?

It exercises time estimation and divided attention — keeping track of several intervals at once and acting on each at the right moment. Those are real cognitive skills; the blind timers and decoys turn a simple stop-the-clock idea into a genuine juggling act.
