Puzzles for Syndication

Indigo Puzzles provides Sudoku, Kakuro, Hashi, Hitori and other puzzles for syndication and we can produce packs for your organisation.

We create high quality puzzles, guaranteed uniquely solvable and never requiring guesswork. We can adjust the difficulty levels to suit, and we concentrate on creating puzzles that feel satisfying to solve, that lead players on a trail and show them new ideas and techniques along the way.
