Two grids, one mismatched tile. Find it before the clock runs out.
Ready when you are
Spot the Difference is a five-round visual comparison test. Two grids of color tiles sit side by side. They are identical except for a single tile whose color is slightly different between the left grid and the right grid. Find that tile and tap it before the ten-second clock runs out.
It is a close cousin of the Imposter variant, but the skill is different. Imposter asks you to find the odd tile within one grid. Spot the Difference asks you to compare two grids and find where they disagree — a side-by-side scan rather than an internal one.
Round one is a small grid with an obvious shift. Each round adds more tiles and shrinks the color difference, so by round five you are comparing twenty pairs of tiles for a shift small enough that some people cannot see it without leaning in. The differing tile is shifted in one HSV channel chosen at random, so you cannot rely on always hunting the same kind of change.
A correct tap scores 10 points plus up to 2 bonus for speed, so a perfect run is 60 across the five rounds. A wrong tap or a timeout scores zero for that round. The bonus rewards quick eyes, but the later rounds are hard enough that simply finding the tile at all is the real achievement.
