Cornered: the Logical Jigsaw
It looks like a jigsaw, but really, this is a mind-bending logic puzzle!
Every month, Pavel publishes a new paper-and-pencil logic puzzle, crafted by Countess Ada Lovelace, daughter of Lord Byron, and oft-reputed first computer programmer. The puzzles are all available for free, and you can earn a discount on our physical puzzles simply by solving the current month's ænigma!
Even better, we are now also hosting a contest every month, where a randomly selected solver will receive a free physical puzzle!
