Puzzle Vault (2026)

A calm collection of offline puzzle games for iOS and Android, built with a partner. A new puzzle arrives every day, alongside 1,300+ hand-tuned levels across 10+ games: block puzzles, water sort, pipe connect, pentominoes, color mixing, Lights Out and more. No ads, no lives, no timers.

The app is built with Kotlin Multiplatform, with the puzzle games running on Godot. RevenueCat handles the one-time purchase and tips, and Firebase powers the daily puzzle and accounts.
