About the Gemstones What's Missing? Game
A picture-recall challenge based on the classic parlour game. Study a board of pictures for a few seconds, then one quietly disappears — can you say which? Rounds get bigger and faster as you go, and three wrong answers ends the run.
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 and memorise every picture on the board.
- After a few seconds the board hides and one picture is removed.
