There's a great puzzle game out there I encountered a while back called "Jewel Quest".

Jewel Quest 2 is the best version of it to date (1 is alright, and 3 sucks, but two rocks!) and share some similarities to BeJeweled and other jewel games out there, but is considerably more fun, because you're not after volume, but rather you're out to turn squares gold, which makes it considerably more challenging.

So I was wondering if there's a FOSS equivalent of this, and if not, could someone make one? This game is tons of fun, and I'd love to see it get ported to the NITS if possible. Thanks.
