About the Sherlock Holmes Spot the Difference Game
The classic puzzle-page favourite, digitised. Two picture boards sit side by side, identical at a glance — but one tile in the second board has been swapped. Compare carefully and tap the tile that changed before time runs out.
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. Two boards appear, looking identical.
- Compare them tile by tile — one has been swapped for something different.
- Tap the changed tile, on either board, before the timer runs out.
- Each round adds more tiles and less time. Three misses ends the run.
Why Play Spot the Difference?
- Trains comparative visual attention and detail-spotting
- A calmer pace than reaction games, but still a real challenge as boards grow
- The same skill used in "spot the difference" puzzle books, now with a timer and a score
