Starting in March 2022, we started designing and publishing original puzzles for our Boosters. These will be robust, layered puzzles, often with custom illustration. Some might take a half-hour to solve; some might take you a few days.
Below is an example of a Mystery puzzle. This one was made as part of Pilcrow Bar, the game we made for Alinea in 2020.
To have access to these puzzles, you will need to sign up to be a Signals Boosters.
