Without needing to rePlay my moves, I’d appreciate being able to watch them back. I would also appreciate the ability to select the level I start on given what levels I’ve previously passed. ### 5/5 — I love this game. *2022-02-02* It only takes a few seconds to get started. Just one rule. Then placing the pieces turned into an interesting puzzle. After a few rounds I had collected enough points to activate some of the super powers, which made spotting dead ends much easier. After hours of fun and having figured out some repeating patterns, I have now reached level 17 (hard), still enjoying this game. ## Frequently asked questions about Stepping Stone Puzzle ### What is Stepping Stone Puzzle?
