Grid & Cage | HTML5 Puzzle Game is a complete, production-ready HTML5 logic puzzle game built for commercial distribution. This game offers three distinct Sudoku variants – Killer Sudoku, Jigsaw Sudoku, and Diagonal Sudoku – all powered by a single shared 9x9 engine. It requires no external JavaScript dependencies and runs on any modern browser directly from a static file host without a build step.
Overview
Grid & Cage bundles three Sudoku variants on one shared 9x9 engine: Killer Sudoku (cages that sum to a target, with no repeated digit inside a cage), Jigsaw Sudoku (nine irregular regions replace the classic 3x3 box), and Diagonal Sudoku (classic box rules plus both corner-to-corner diagonals).
Every puzzle is generated procedurally at play time – there is no bundled puzzle list. The game features Easy/Medium/Hard difficulty tiers plus a seeded Daily Challenge, five selectable board themes (each with its own fixed background image), a shared XP progression system with seven rank tiers, a local best-times leaderboard, an eight-achievement system, a configurable hint system, and a full sponsor/ad integration framework – all in a single self-contained HTML5 package.
About the Game
Entry point is index.html – no build step, no CLI tools, no package manager required.
Pure vanilla HTML5, CSS3, and ES6+ JavaScript – zero libraries, zero frameworks.
Game engine and UI for all three puzzle modes are contained in a single IIFE in scripts/js/game.js.
There is no bundled puzzle file – Killer, Jigsaw, and Diagonal Sudoku boards are all generated algorithmically at runtime, for every difficulty tier.
All CSS lives in scripts/css/style.css; sponsor/ad placeholder in scripts/sponsor/sponsor-placeholder.html.
Ads are switched on or off from a single file: scripts/config/ads.js.
