Blind 10 | Sensorium

Perception game notes

Blind 10 starts with a visible rhythm and then hides the timer. The challenge is to stop as close as possible to ten seconds without watching a clock.

Signals tested

internal time sense
rhythm retention
late-run patience

How scoring works

The result reports timing error in seconds and compares the average of a five-attempt set against the target window.

Practice note

The best strategy is to keep a steady internal pulse instead of counting faster as the hidden timer approaches ten.

How to play

Start the round and watch the calibration rhythm.
Continue counting after the timer display disappears.
Stop when your internal clock reaches ten seconds.

How to read the result

Early stops usually mean the count compressed as the display vanished. Late stops often mean the last seconds stretched while waiting for certainty.

Accessibility note

Sound can help with rhythm, but the visible calibration pulse and text result make the round playable with audio disabled.
