Description
Three Sudoku Variants in One HTML5 Puzzle Game
Grid & Cage is a complete, production-ready HTML5 logic puzzle game that brings three Sudoku styles together on one shared 9×9 engine. Players can enjoy Killer Sudoku, Jigsaw Sudoku and Diagonal Sudoku without switching games, making it a strong choice for puzzle sites, game portals and educational collections.
Fresh Puzzles Every Time You Play
Instead of relying on a fixed puzzle list, Grid & Cage generates every board procedurally at play time. That means no two games need to feel the same, and returning players always have a new challenge waiting for them.

Built Lightweight, With No Dependencies
Grid & Cage is built with pure vanilla HTML5, CSS3 and modern ES6+ JavaScript, with no libraries or frameworks required. The game starts from index.html with no build step, command-line tools or package manager, and its engine and interface are contained in a single file. Styling is kept in a separate stylesheet, while advertising can be switched on or off from a single configuration file.
Who Is It For?
This game suits commercial distribution as a standalone puzzle product, HTML5 and mobile game projects, and educational use where Sudoku offers a fun brain-training exercise. Its clean, dependency-free structure also makes it easy to deploy and customise for your own site or game catalogue.
