Three Logic Puzzles in One HTML5 Game

Logic Grids brings three different brain-training puzzles together in a single, ready-to-run HTML5 package. Instead of offering just one puzzle style, it lets players switch between inequality grids, crossword-style number sums, and fast tile-clearing challenges, so there is always a fresh way to test logic and number skills.

What You Get

• Futoshiki Equation: solve a 1-9 grid using greater-than and less-than clues to place every number correctly.
• Kakuro / Cross Sums: fill crossword-style grids so each run of numbers adds up to its clue sum.
• Number Match: clear tiles in three sub-modes — Classic, Ladder Rush, and Sum Chain.
• Procedurally generated puzzles at runtime, giving endless replayability without pre-bundled puzzle lists.
• Easy, Medium, and Hard difficulty levels to suit beginners and experienced puzzle players.
• A daily challenge with a new seeded puzzle every day.
• Five board themes to personalize the look of the game.
• An XP progression system with ranks and achievements to unlock through play.
• A local best-times leaderboard for tracking personal progress.
• A configurable hint system to help players through difficult puzzles.
• A sponsor and ad integration framework for monetization opportunities.

Designed for Easy Play on Any Device

The clean, modern interface is built for intuitive navigation, and the responsive design adapts to different screen sizes. Built with HTML5, CSS3, and ES6+ JavaScript, it works in modern browsers on desktop and mobile, loads quickly, and uses well-structured code that is easy to read and maintain.

Simple to Customize and Set Up

The game is structured around a main index.html file and a JavaScript game file at scripts/js/game.js. Players and site owners can choose from five pre-designed board themes or create their own with the provided CSS framework, customize sound effects with the Web Audio API, and enable or disable the ad integration framework as needed. Setup is straightforward: extract the package and open index.html in a web browser.

Who It Is For

Logic Grids is a strong fit for website owners who want engaging, replayable content, game developers looking for a solid logic-puzzle base to build on, and educators who want a practical way to teach logic, problem-solving, and critical thinking.
