Bottle Sort Puzzle – Android Game (Java, Native UI)

Calming bottle-sort puzzle with 500 handcrafted levels, undo/restart/hints, dark mode, smooth canvas bottles, and ready hooks for AdMob/IAP monetization. Built entirely in Android Studio (Java, API 23+).

Bottle Sort Puzzle is a complete, production-ready bottle sorting puzzle game where players tap bottles to pour colored liquid until every bottle contains only one color.

The project includes a deterministic 500-level progression system, smooth animations, sound effects, dark/light themes, star-based scoring, and persistent player progress.

The game is written entirely in pure Java using custom Canvas rendering. No external game engines or heavy third-party SDKs are used. This makes it lightweight, fast, and easy to customize or reskin for publishing on the Play Store.

Perfect for developers who want to quickly launch a puzzle game with ads, expand gameplay, or rebrand the project.
