This pack celebrates the 1 year anniversary of the Dutch Flat Mates constraint by Flinty. They all use a 6x6 variation of the Dutch Flat Mates constraint called Polish Flat Mates. Thanks to the testers. Hope you enjoy!

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.
• German Whisper Lines: Adjacent digits on a green line differ by 3 or more.
• Renban Lines: Digits on a pink line form a set of non-repeating consecutive digits in any order.
• Successor Arrows: If a digit N is in an arrow cell, the digit N+1 must be placed N steps away in the indicated direction. e.g. if r1c5 is 2, then r1c3 is 3.

Volume 1?

I have a few more of these lined up and will likely release them soon. This pack is meant as an introduction to the constraint. Edit: Volume 2 is released now!
