Question 1

What is Spot the Difference?

Accepted Answer

A free attention game where you compare two walls of emojis and tap every cell that has been altered on the bottom wall. The game is known in Swedish as Finn fem fel ("find five errors") · the traditional name for spot-the-difference puzzles in Swedish newspapers and children's magazines.

Question 2

How are the differences chosen?

Accepted Answer

Two ways. The first is a visual swap · a hand-curated cluster of look-alike emojis (smiley faces, red fruits, coloured circles, numbered clocks) means the replacement is genuinely close to the original. The second is a horizontal flip or 180° rotation, applied only to emojis where the flipped form is plausible (animals with a clear orientation, vehicles, tools) - flipping a star or heart would be invisible, so those are excluded.

Question 3

How big can the wall get?

Accepted Answer

Up to 500 emojis on a single screen. The grid is always a perfect rectangle (no row sticks out at the bottom) and the column count adjusts automatically to your screen aspect so cells stay roughly square. On a phone in portrait you get a taller, narrower wall; on a desktop a wider one.

Question 4

What happens when I tap the wrong cell?

Accepted Answer

The round ends immediately. The streak counter resets and you can start a new wall. No second chances · same rule as Ghost, Polyglot, and the rest of the streak games.

Question 5

Can I play offline?

Accepted Answer

Yes. PlayMemorize is a Progressive Web App with every emoji bundled at install time. Once loaded, Spot the Difference works without an internet connection.
