The puzzles of Nathan Curtis had once been available in Will Shortz Presents Wordplay magazine and on the Tortoiseshell Blog, but Wordplay magazine recently published its final issue and the blog has been dormant for months. But fear not, Tortoise fans: Nathan just gave me a heads up on his new Tortoiseshell Studio blog. The site contains some archive puzzles and will feature new puzzles following an announcement next week. I’m looking forward to the renewed access to Pathfinders, Marching Bands, and other variety puzzles that Nathan comes up with. Check it out!
