Gray Design Associates says Jigsaws Galore — now up to version 7.0.9 — has come to the Mac. It’s available at the Mac App Store in the Games category for US$2.99.
Jigsaws Galore is a jigsaw player and creator that can purportedly handle jigsaws from 4 to 64,000 pieces. It’s configurable; almost every facet of the game can be adjusted while solving a jigsaw, even down to the thickness of the pieces.
A large number of additional jigsaws is also available at the game’s website (http://www.jigsawsgalore.com). Jigsaws Galore requires an Intel-based Mac running Mac OS X 10.6.6 or higher.
