ChainLink puzzle supplier

High-quality ChainLink puzzles for newspapers, magazines, puzzle books, websites and mobile apps.

Every puzzle is generated using our in-house software, has a unique solution, and is designed to be solved logically without guessing.

Chainlink puzles are similar to Sudoku - for a n×n grid, every row and column must contain the number 1 - n exactly once. Additionally, each cell is in a chain of n cells, and every chain must also contain the numbers 1 - n exactly once.

They are very similar to Jigsaw Sudoku puzzles.
