gridy

Gridy is a puzzle book based on grids, duh. It is based on some aspects of BoBoGram (I highly recommend playign it), Taiji (if you know what symmetry is it isn't required) and Understand (at least watch the playthrough on yt to understand). It was made to be a challenge but the difficulty might vary so you might get stuck on primary puzzles.

The puzzle book is still in cbadevelopment
