Kintsugi Sudoku | 3D Style HTML5 Puzzle Game

Kintsugi Sudoku is a fully responsive HTML5 Sudoku puzzle game inspired by the Japanese art of Kintsugi. It combines classic Sudoku gameplay with a distinctive dark lacquer and golden-seam visual style, creating an elegant puzzle experience for desktop and mobile browsers.

The game uses a 2D implementation with a 3D-style visual aesthetic. The 3D-style appearance refers to the visual presentation, including depth effects, shadows, layered surfaces and dimensional interface elements. It does not use a 3D engine or real-time 3D rendering.

Players can choose from four difficulty levels, track their solving time and mistakes, use notes and hints, pause and resume their game, and continue unfinished puzzles. The game also includes a statistics system for tracking personal performance and best results.
