3×3 PATTERN · 15 ROUNDS
Scan the pixel pattern and select the one empty position.
Complete 15 patterns. Wrong picks and timeouts reduce accuracy, but the test continues.
READY?
One part of the 3×3 pixel pattern is missing. Choose its position.
Keyboard: use 1–9 in the same visible 3×3 layout · Touch or mouse: choose the empty tile
HOW TO PLAY
Start a run and scan the full 3×3 design for the outlined empty position.
Tap it, click it, or press its visible number key. Keys 1–9 follow the grid from top-left to bottom-right.
Finish 15 standard rounds, or protect one life while the endless deadline shrinks.
PATTERN SCANNING
You must detect a break in a structured pixel design, map its position to one of nine responses, and act before the deadline.
The tiles use distinct outlines and geometric marks, so the missing location remains identifiable without relying on color vision.
READ YOUR RESULT
Average and best times use correct answers only. Accuracy includes every wrong selection and timeout in standard mode.
For fair comparisons, repeat the test on the same device and with the same input method. Screen size and input latency can affect times.
QUESTIONS
Timing starts when the 3×3 design appears and stops when you choose a position. Only correct responses contribute to average and best time.
Standard mode records the miss and moves to the next pattern. Endless mode ends immediately on the first wrong choice or timeout.
Keys 1, 2, 3 are the top row; 4, 5, 6 the middle row; and 7, 8, 9 the bottom row. Each tile displays its key.
No. The gap is shown by an empty dashed tile among solid outlined geometric marks, so structure rather than hue identifies the answer.
