Where Code Meets Puzzle

The name Codoku is a playful twist on "Code" and "Sudoku", inspired by the intersection of programming logic and puzzle-solving. The game is built using HTML, CSS, JavaScript, Bootstrap, and JQuery with an emphasis on accessibility, responsiveness, and user-friendly design.

At its core, Sudoku is a game of logic making it the perfect canvas for showcasing how code can simulate reasoning and decision-making. Codoku takes advantage of this by using modular functions and interactive JavaScript to mirror the problem-solving nature of the puzzle itself. Using DOM manipulation, event-driven architecture, and API logic, Codoku showcases how traditional puzzles can evolve into interactive learning opportunities for both players and developers alike.

Features such as event triggers for real-time feedback, differentiated puzzle modes to suit various skill levels, and intelligent hint controls that guide without giving away the game all contribute to a more dynamic and personalized user experience. These interactive elements not only make Codoku more engaging but also demonstrate the power of thoughtful front-end development.

A Puzzle With Purpose

This project is also about more than just code. It’s a tribute to cognitive health and mental agility — two things that matter deeply in the fight against dementia. Sudoku puzzles are known to support memory, concentration, and logical thinking, making them a valuable activity for keeping the brain engaged and active at any age.That’s why we’ve chosen to spotlight the work of Alzheimer’s Society, a UK charity supporting people affected by dementia.
