About PlayMemorize Finn fem fel

Finn fem fel ("find five errors" in Swedish) is a free spot-the-difference game. The screen shows two identical-looking walls of emojis, one above and one below. The bottom wall has been altered in a few places · your job is to tap every changed cell.

Pick your wall size. Choose from 100, 200, 300, 400, or 500 emojis · the cells shrink to fit the screen so the game always fills the viewport. The wider the wall, the smaller the haystack-needle target.

Pick how many differences. 1, 5, 10, or 20 alterations. Two ways the bottom wall can lie · a similar emoji has been swapped in (a different smiley from the same family, a different shade of red), or an emoji has been horizontally flipped or rotated 180°. Both tricks are seeded, so the same difficulty + seed always renders the same wall.

One wrong tap ends the round. Streaks count how many walls you clear in a row. Twemoji rendering means every emoji looks identical across iOS, Android, and Windows · no platform shortcuts.

Part of the PlayMemorize family of free brain-training games. Runs entirely in your browser, works offline as a Progressive Web App.

常见问题

Q: What does "Finn fem fel" mean?

It is Swedish for "find five errors" - the traditional name for spot-the-difference puzzles in Swedish newspapers and children's magazines. The game lets you pick anywhere from 1 to 20 differences, but the name nods to the classic.

Q: How are the differences chosen?

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.

Q: How big can the wall get?

Up to 500 emojis on a single screen. The grid columns adjust automatically to your screen aspect ratio so cells stay roughly square; on a phone in portrait you get a taller, narrower wall, on a desktop a wider one.

Q: What happens when I tap the wrong cell?

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.

Q: Can I play offline?

Yes. PlayMemorize is a Progressive Web App with every emoji bundled at install time. Once loaded, Finn fem fel works without an internet connection.
