Spot the Difference Grid — Find the Changed Cell
Two grids look identical except for one cell. Memorize the first, then tap the cell that changed in the second.
How to play
- Click Start — Grid A appears; memorize the colors.
- After a moment Grid B replaces it with exactly one cell recolored.
- Tap the cell that changed color.
- Correct taps advance you; the grid grows every few rounds.
- Click Finish whenever you like to lock in your score and beat your best.
Two versions of a colored grid are shown one after the other. The second is identical except for a single recolored cell. Study the first grid, then tap the cell that changed in the second. The grid grows larger as you climb the rounds, stretching your visual memory.
Frequently asked questions
- How long do I get to study the first grid?
- About 1.8 seconds. The grid then redraws with one cell changed and you tap the difference — so quick, deliberate scanning beats trying to memorize every cell.
- Does the grid get harder?
- Yes — every couple of rounds the grid adds a row and column (up to 6×6), making the single changed cell harder to find.
