-Normal sudoku rules apply.

-Between Lines: Digits along a grey line must be strictly between the digits in the attached circles. But these grey lines are partially obscured, solvers have to determine which path they have taken.

-German Whispers lines: Adjacent digits along a green line must have a difference of at least 5.

-Region Sum Lines: Digits on a blue line have the same sum in each 3x3 box the line passes through. The sums may differ from line to line.

-Renban Lines: Digits along a purple line form a nonrepeating consecutive set, in any order.
