Nice puzzle. But the solution path for this requires specific tricks that I would pin at 3* level.

I really enjoyed how similar (i.e. the parity constraint) and yet extremely different this was from the previous puzzle in the series! I particularly liked the break-in on this one.

Pretty easy if you know the "trick", probably pretty tough if you dont. Thanks for sharing. Another nice entry to this series.
