Rules and objective
Find the one tile whose brightness differs from the other 24 tiles. The hue changes by level while the odd tile is assigned a distinct lightness value and random grid position.
How scoring works
Every correct identification advances the level; later differences become progressively subtler. Scores are saved only in this browser's local storage, so changing devices or clearing site data starts a new local record.
What we checked in this build
We checked that wrong taps do not advance the level and that all tiles retain accessible labels.
This note describes the Starbox implementation rather than the rules of every similarly named game elsewhere.
Follow one path through the grid
Start at the top-left, move across the first row, then reverse direction on the next row in a snake pattern. A fixed path ensures every tile receives attention once. Random eye movements often compare the same central tiles repeatedly while skipping a corner.
Compare neighbors, not memory
Human color memory is weak over even a short interval. When a tile seems different, compare it with the tile directly beside and below it. The surrounding majority supplies a live reference. If the difference remains visible in both comparisons, the candidate is stronger than a vague impression based on the whole board.
Use brightness boundaries
Do not search for a color name. Look for a tile whose edge appears slightly brighter, darker, warmer, or cooler than adjacent edges. On difficult rounds, soften your focus and notice where the grid stops looking uniform. Avoid changing screen brightness between attempts because it alters the contrast you are learning to detect.
Protect accuracy as difficulty rises
A wrong tap costs more than an extra second spent confirming a candidate. When shades become closer, slow the scan and use two-neighbor verification. Compare sessions on the same display and lighting; results from a bright phone outdoors and a calibrated desktop indoors are not equivalent.
