About the company
Hamilton Digital Media Limited creates puzzle websites, mobile games, and puzzle books. Alongside our puzzle publishing, we build practical calculators and tools for everyday activities.
Company story
Hamilton Digital Media Limited is the company behind a network of puzzle and thinking-game projects. Our puzzle portfolio includes browser puzzle sites, Android games, and printed puzzle books, all shaped around the same idea: simple rules can create deeply satisfying problems.
Brian Hamilton leads the company, bringing experience in web development, mathematical software models, and puzzle systems. Karan Hamilton contributes puzzle design, testing, wording, and player experience. Their puzzle work combines traditional publishing with practical web-game engineering.
Puzzle publishing
Sudoku, logic-grid puzzles, code-breaking games, and clue-based challenges where progress comes from reasoning.
Word search, pattern recognition, and quick browser puzzles for people who enjoy short, focused solving sessions.
Card games, dice games, movement puzzles, bluffing games, and strategy formats where each decision changes what happens next.
Puzzle experiences that can be enjoyed by adults, younger players, grandparents, parents, teachers, and casual solvers.
Practical tools
Building puzzle sites also means building the tools behind them: solvers, generators, helpers, and systems that turn rules into something people can use. Brian brings that interest in tool making to a separate family of practical calculator websites.
The Toolbox sites cover pools, brewing, aquariums, lawns, cycling, RVing, soap making, and sports betting. Each has its own subject and audience, with Hamilton Digital Media as the company behind the work.
