Grid and Numbers

• Board sizes range from 4x4 to 9x9.
• In an N x N grid, you use the numbers 1 to N.
• The position of numbers is not ordered - only the rules matter.

Rows and Columns

• Every column must contain all numbers from 1 to N.

Chains

• The grid is divided into chains - groups of connected cells.
• Each chain contains exactly N cells.
• In each chain, all numbers from 1 to N must appear once.

Given Numbers

• Some cells are prefilled and cannot be changed.
• These numbers serve as clues to help you solve the puzzle.
