Puzzle Details

All puzzles use normal 6x6 sudoku rules and Polish Flat Mates. Each puzzle contains one additional constraint.

• 6x6 Sudoku rules: Place the digits 1-6 in every empty cell such that no digit repeats in a row, column or box.
• Polish Flat Mates: Every 2 in the grid needs a 1 directly above it or a 4 directly below it. It may have both, but it doesn't need both.
• Quadruples: Digits in a circle appear at least once in the surrounding cells.
• Row/Column Indexers: A red cell in column n indicates the column where the digit n appears in its row (e.g. a 3 in R2C5 puts a 5 in R2C3). A blue cell in row n indicates the row where the digit n appears in its column (e.g. a 3 in R1C4 puts a 1 in R3C4).
