📖 About This Mix Puzzle Android Source Code

Mix Puzzle is a complete, ready-to-publish Android puzzle game source code written in Java using Android Studio. The game shuffles a real photo into a grid of blocks and challenges the player to rebuild the original picture in the shortest time possible. Two gameplay modes are included out of the box - Rotate mode (tap blocks to rotate them) and Slide mode (classic 15-puzzle style sliding). The project ships with 10 hand-picked photo categories (Animal, Aquarium, Architecture, Bike, Bird, Car, City, Flowers, Food, Nature) totalling 120+ playable levels, with per-photo best-time tracking stored in a local SQLite database. With AdMob banner ads already integrated, this is one of the fastest complete Android games to rebrand, reskin and upload to Google Play.

What end-users get:

• 🧩 A relaxing photo puzzle game with two distinct play modes (rotate & slide).
• 🖼️ A modern category grid with cover thumbnails for each pack of levels.
• ⏱️ A built-in timer + best-time record per photo to keep players coming back.
• 🔊 Background music + click / move / win sound effects with an in-game mute toggle.

✨ Key Features

🕹️ How the Game Works for the End User

1. Open the app - a 2-second branded splash screen welcomes the player.
2. Pick a photo category from the grid (Animal, Car, Nature, Food ...).
3. Swipe through the photos in that category and tap PLAY on any one.
4. The chosen image is shuffled into a grid of blocks - the timer starts.
5. In Rotate mode, tap a block to rotate it 90°; in Slide mode, tap a block next to the empty slot to slide it.
6. Reassemble the original photo. When the image is complete a "COMPLETED" screen appears with the elapsed time.
7. The new time is compared against the best time for that photo and saved if it is a new record.
8. Open the in-game Settings to mute the sound or swap between Rotate and Slide modes at any time.
