About the Gemstones 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.
Diamonds, crystals, crowns and buried treasure — the gemstone deck glitters with everything a rockhound or jewel thief could dream of. Dig deep and unearth the matching pairs.
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
