Are you sure there's only 3? The full title is the hint.
There is 60 purple gems XD ?
Actually I got 4 before I just missed the count and it stop the game at the 4th, I don't get the title's hint xD
Hahaha, just 4 purple gems. The hint is "There and back again". And since you got all 4, that's good and you didn't need the hint.
