About the Sherlock Holmes Odd One Out Game
A rapid visual-scanning challenge. A grid fills with the same picture repeated over and over — except one tile, which is different. Spot it and tap it before the clock runs out. Every round the grid grows and the clock gets tighter.
Conan Doyle's original Sherlock Holmes stories are in the public domain, so we're free to celebrate the great detective properly. Deerstalkers, magnifying glasses, dossiers and the fog of Victorian London await.
How to Play
- Press Start. A grid appears — almost every tile shows the same picture.
- Scan the grid for the one tile that is different.
- Tap it before the timer runs out.
- Each round adds more tiles and less time. Three misses ends the run.
Why Play Odd One Out?
- Trains rapid visual scanning and selective attention
- No memorising required — pure focus under time pressure
- Short, snappy rounds that get genuinely tricky fast
