Last Control
Sign in · Operator entrance
A go/no-go line. Clear the compliant. Hold the flagged.
Twenty units cross the inspection line, one at a time, a beat each. Tap CLEAR to pass a compliant unit. Do nothing to a flagged one — let the beat run out and it is held. Wave a flagged unit through and the protocol counts your hand. Free, in the browser, no sign-up.
No download. No account. One beat per unit. Every wrong wave is filed. Everything is.
Each unit holds for one beat. Tap CLEAR only for a compliant unit. Do nothing to a flagged one — waving it through is counted.
The full audit runs in the game. Free. Anonymous until you claim a seat.
Frequently filed questions
Is this go/no-go test free?
Yes. Free, browser-playable, no sign-up, no download. Nothing is filed off this page unless you choose to continue into the game.
What is a go/no-go test?
A response-inhibition drill. Most units call for a response — you act fast. A minority call for you to withhold — you must stop the response you were already making. It is used to gauge impulse control and sustained attention: how well you hold your hand back on the rare do-not-act cue. Here the units cross an inspection line; clear the compliant ones, hold the flagged ones.
What does it measure?
Two things the score keeps apart: how many compliant units you cleared in time (attention and speed), and how many flagged units you wrongly waved through (impulse control). Waving a flagged unit through is the error that counts most — it is the hand moving before the eye has finished.
Is this a real cognitive or medical assessment?
No. It is a game. The rating is a game score for entertainment — it does not measure intelligence, diagnose anything, or stand in for any professional assessment.
