PIXEL SORTING · 24 PACKAGES
Read the current rule and route each package before the sorting line.
Sort 24 packages with exactly 12 LEFT and 12 RIGHT answers. Mistakes count, then play continues.
READY?
Rules can use package shape or color. No aiming required.
Keyboard: A or ← sends LEFT · L or → sends RIGHT · Touch or mouse: use the two large buttons. No aiming required.
HOW TO PLAY
Read the rule board. It names one shape or color and tells you where matching packages go.
When the package appears, compare its visible shape and color with the current rule.
Send it LEFT or RIGHT before the package reaches the striped sorting line.
RULE-SWITCHING REFLEX
Each round combines visual feature recognition, a visible mapping rule, and a fast two-choice response. The rule may switch between shape and color.
The package is always clearly encoded by both shape and color. Classification uses buttons or keys and never requires pointer aiming.
READ YOUR RESULT
Standard accuracy includes all 24 packages. Average and fastest times use correct sorts only, measured from package appearance.
Endless mode switches rules and accelerates the belt after every correct package. One error or timeout ends the run.
QUESTIONS
For CIRCLE → LEFT, every circle goes left and every non-circle goes right. The second half of the rule board always confirms the other direction.
Yes. Standard mode contains exactly 12 correct LEFT responses and 12 correct RIGHT responses in shuffled order.
Press A or Left Arrow for LEFT and L or Right Arrow for RIGHT, or use the two large on-screen buttons.
The classification rule keeps switching and the belt speeds up with your streak. One wrong sort or timeout ends the run.
