Two panels look almost identical. Tap every shape that's different between them before the timer runs out.
The screen splits into a top and a bottom panel filled with the same set of shapes. Some shapes are subtly different between the two — a color swap, a size change, a position shift, or a different shape altogether.
Tap any shape that has been changed (in either panel works; it counts in both) to mark it found. A small green ring confirms the find.
Clear every difference before the timer hits zero to win the round and advance. Each new level adds shapes, adds differences, and shaves seconds off the clock. A wrong tap doesn't end the round but costs two seconds — be sure before you tap.
You have three lives. Run out of time before finding every difference and you lose one; lose all three and the run is over. Each difference found scores 100, plus a 200-point bonus for completing the round.
Scan a row at a time, not the whole panel. The brain anchors on local pairs faster than on global differences. Sweep your eyes left-to-right across the top panel's first imaginary row, then the same row in the bottom panel — a swap stands out the second your eyes do the comparison side by side.
Color swaps are the easiest, position shifts are the hardest. Train the easy ones first to bank score, then narrow your search to shapes whose positions look almost-but-not-quite the same. A 25-pixel shift will read as 'I think it's slightly to the right' even when you can't articulate why.
Don't tap until you've confirmed in both panels. The cost of a wrong tap (two seconds) is almost always worse than the cost of taking one more second to verify. If you have to ask yourself whether it's a difference, it isn't.
Later levels squeeze the timer hard. Save the size-changed and type-changed differences for last — those jump out at a glance and become 'free' finds in the final seconds when you're sweeping in a panic. Burn the deep scrutiny on color and position differences while you still have a calm clock.
