Logic Masters Deutschland e.V.

This is a pairdoku. Two standard sudoku puzzles with the same solution meant to be solved simultaneously by two solvers who are communicating but cannot see each other's grids. The solution is only unique when the two grids are solved together.

We encourage you to not look at the other grid and not to share the type or location of constraints in your grid. Instead, communicate pencilmarks and interesting relationships between those pencilmarks. Have fun!

Full rules for all constraint types that appear are included at the links below, but are omitted here to avoid spoiling the surprise.

Have fun, leave a comment if you enjoy the puzzle!
