Press start to reveal the first set of target squares.
VM · Perception
Start a level and study the highlighted squares during the brief reveal. When the marks hide, select the remembered locations. Correct selections stay marked, while a wrong square costs one of your three lives. A level completes when every target square has been found.
The board begins as a 3 by 3 grid with three targets. As you complete levels, the target count grows gradually and the grid expands every three levels, up to 7 by 7.
Your score is the number of completed levels. Targets are unique within each level and generated by shuffling the grid cells, then taking the needed count. Higher scores are better.
Screen size, browser zoom, contrast perception, touch accuracy, distractions, and system load can all shift a run. Results are for entertainment and general information, not medical, diagnostic, neurological, or IQ claims.
Each run starts with three lives. A wrong square removes one life, and the run ends when all three are gone.
The game starts at 3 by 3. Every three completed levels, the grid side length grows by one until it reaches 7 by 7.
No. Each level creates unique target squares with a Fisher-Yates shuffle before the brief reveal.
