I wanted to create another multi part puzzle, but with an easier difficulty than the last ones. Here is what I came up with :)

Normal Sudoku rules apply.

Digits separated by a black dot are in a 1:2 ratio. Digits separated by a white dot are consecutive. Not all dots are given.

Dynamic Fog: Deducing the digit in the highest visible checkpoint (marked with a green square and a number) will reveal new cells and potentially a new checkpoint.

Each line follows a specific constraint type from a list of constraint. It is up to the solver to determine which line belongs to which type.

Each line constraint type may contain no repeated digits anywhere in the puzzle.

At the start of the puzzle, all lines are Region Sum Lines (Box borders divide the lines into equal sums).

Dynamic Lines: When a new checkpoint is revealed, remove the determined line types and all entered digits except those on checkpoints. You are now allowed to new line constraints.

Checkpoint 1: Additionally, the lines can now be German Whisper lines (Adjacent digits differ by at least 5)

Checkpoint 2: Additionally, the lines can now be Parity lines (Digits alternate between odd and even digits)

You have completed the puzzle when all 3 checkpoints are revealed and the complete grid is filled.
