SPATIAL FOCUS · 24 ROUNDS
Read the center cue, but respond to where the target actually appears.
Play 24 balanced valid and invalid cue rounds. Mistakes count, then play continues.
READY?
The cue is often helpful, but the target can appear on the other side.
Keyboard: A for left, L for right · Touch or mouse: select the target zone.
HOW TO PLAY
Keep your eyes near the center and wait for a left or right arrow cue.
A target appears after a short interval. It may match the cue or appear opposite it.
Press A or L—or tap the left or right zone—according to the target, not the cue.
VALID VS INVALID
A valid cue points toward the upcoming target. An invalid cue points away, asking you to redirect focus before responding.
The standard test balances both cue types and both target sides so the comparison is not dominated by one direction.
READ YOUR RESULT
The two averages include only correct responses. The difference is invalid average minus valid average.
This browser game is a focus challenge for entertainment and personal comparison, not a diagnostic assessment.
QUESTIONS
No. The arrow is only a cue. Always respond to the side where the square target appears.
An invalid cue points left before a right target, or points right before a left target.
The 24-round set contains six rounds each of valid-left, valid-right, invalid-left, and invalid-right, shuffled into a new order.
A wrong side, an input before the target, or a timeout ends the run immediately.
