Sudoku - Complete Game

Sudoku is a complete, ready-to-publish puzzle game for Android and iOS, built in Unity. It comes with 1,200 puzzles in four difficulties, an in-app purchase shop, ad support and a full set of daily and progression features, so you can reskin it, add your ad network and release it.

Gameplay

Players fill a 9x9 grid so that every row, column and 3x3 box holds the digits 1 to 9. Tapping a cell highlights its row, column and box and every cell with the same number. Notes mode adds pencil marks, which are cleared from the row, column and box automatically when a number is placed. Erase clears a cell, Undo takes back the last move, and a number button disappears once all nine of its digits are on the board. The Hint power-up fills in the selected cell, or a random unsolved one, with the correct number.

The 1,200 puzzles come in four difficulties, 300 each: Easy, Medium, Hard and Expert.

Progression

Tech

- ScriptableObject configs for every manager, assigned in the Inspector

- Local JSON save system with batched writes

- Event bus, object pooling and a screen, popup and HUD UI system with transition animations

- String ID types with Inspector pickers for screens, sounds, resources, events and more

- Debug console in development builds (time controls, challenge progress, commands)

Easy to customize

The game's own code is 7 scripts in Assets/BizzyBeeGames/Sudoku/ (namespace BBG.Sudoku). Everything else is the shared BBG framework in Assets/BizzyBeeGames/Framework/. Shop items, rewards, ads, levels and achievements are ScriptableObject configs edited in the Inspector. Puzzles are plain JSON (the clues and the solution as strings of digits), so you can add your own. The UI art is 111 SVG sprites, so it scales cleanly and is easy to recolour. Several BBG games can be imported into the same project and share one copy of the framework.

Included documentation: a guide to each framework system (levels, rewards, conditions, features, achievements, daily puzzle, daily reward, prize wheel, interrupts, shop, notifications, sound), requirements, IAP setup, and a setup guide for each supported ad network.
