GoKawiilPell Puzzles daily logic game expands spiral-tile concept from achromath creator Brandan
Pell Puzzles, a daily browser puzzle made by Brandan, the writer behind the achromath Substack, asks players to draw eight connected paths of lengths 1 through 8 on a 6x6 grid marked with X and O clues. The game grew out of Brandan's January 2024 'Pell Tiles' concept exploring spiral square strips, which he turned into a puzzle format a year later; a daily version has run since December 2025.
