Nice puzzle mechanics! I noticed you mentioned randomness is only used for the initial config. For 'Daily' style puzzles, there's always a segment of the player base that gets skeptical about whether the 'Daily Seed' was hand-picked to be harder or easier (the classic 'Wordle' suspicion).

A cool way to bypass that is to use a public, decentralized beacon (like Drand) as the seed for your generator. It effectively proves to players that you couldn't have rigged today's puzzle, because the entropy didn't exist until the beacon round fired. It's a low-lift way to add a 'Provably Fair' badge to a daily game without needing a complex backend.
