01 / START
Press and hold
The clock begins as soon as you press. Keep holding while you estimate the target shown at the center of the rings.
An invisible clock. Your inner rhythm.
Feel the clock.
How accurately can you feel a second pass? In Syncd, you hold to start time, release when the target feels right, and learn exactly how early or late you were.

The idea
A simple action. A surprisingly precise challenge.
There is no visible stopwatch to follow. The target changes between one and five seconds as you advance, so each release asks for a fresh sense of timing.
02 / STOP
Release on instinct
Lift your finger or mouse button when you think the target second has arrived. The game measures the elapsed time in milliseconds.
03 / ADJUST
Find your rhythm
You see how early or late the release was. Stay inside the timing window to score and reach the next round.
After each release
Every millisecond tells a story.
A stop inside the window earns points based on how much of that window remains. A stop outside ends the run. The timing window responds to your accuracy, so a perfect sync and a near miss feel different.
Curious how the numbers work? We break down the exact score and window rules with examples.
