6x6 Easy Chain Sudoku Puzzles
"Chain Sudoku," also known as "Strimko," is a logic puzzle where you fill circles arranged in a square grid with digits. Some circles come with pre-filled numbers as clues, while others are empty and need to be filled in by the solver. The grid also features several chains, which are sets of interconnected circles.
Chain Sudoku is a logic puzzle that injects a fresh twist into the classic Sudoku formula by introducing chains.

Chain Sudoku is a logic puzzle that offers a fresh take on the ever-popular Sudoku. Like its classic counterpart, it challenges you to fill a grid with numbers, but with a twist: the usual 3x3 boxes are replaced by interconnected chains.
Similarities to Sudoku:
- Like Sudoku, Chain Sudoku uses a square grid filled with circles or squares.
- Some cells contain clues (pre-filled numbers).
- The goal is to fill the empty cells with digits following the same core principle of Sudoku: no digit can be repeated in any row, column, or specific group of cells.
The Chain Twist:
- Instead of the usual 3x3 boxes of Sudoku, Chain Sudoku introduces "chains." These are connected groups of cells that wind their way through the grid.
- The key rule for chains: just like rows and columns, each chain must contain all the digits (typically 1 to the grid size) without repetition.
Benefits of Chains:
- Chains add a new layer of challenge compared to classic Sudoku.
- The variable shapes of chains create unique situations that require different logical approaches.
- Chain Sudoku comes in various grid sizes (from 4x4 to 9x9), offering a range of difficulty levels.
Getting Started with Chain Sudoku:
- Start with the clues, focusing on rows, columns, and chains with the most filled cells.
- Use elimination to remove impossible digits from empty cells based on row, column, and chain restrictions.
- Look for "certainties" - situations where a cell can only hold one specific digit based on the available options.
- Pay close attention to the chains, ensuring all digits within them follow the "no repeats" rule.
