crashgameastronaut.com lets you do exactly that. You can rotate entire reels, adjust their sequence, and even change how symbols interact with each other. I spent a weekend designing my own “Glyph Labyrinth” boards, and the results were surprisingly satisfying — some sequences were much more challenging than anything pre-made. The platform encourages creativity, letting you solve puzzles in multiple ways rather than forcing a single solution. It also features community boards, so you can try layouts other players designed. I’ve never seen a reel-based puzzle system with this level of flexibility. It’s endlessly engaging.
