Twice a month, we’ll email you a puzzle crafted by one of our lovely gridsmiths. Difficulty will vary week to week and will be described as lightly challenging, somewhat challenging, or very challenging.

Comes in PDF, JPZ, and PUZ formats, with a solutions key too.

If you purchased an Inkubator subscription in 2019, or backed the Inkubator Kickstarter at a $100+ tier, you will continue to receive Inkubator puzzles through 2020.
