I love the spiral around the puzzle that cleanly resolves itself in the obvious box. Such clear setting. Well done!

Needed two restarts before I finally got the deduction strategy right (aka being a bit sloppy). Beautiful puzzle, thanks for the construction and sharing.

Very cool. Always nice with a fully colored grid before putting in numbers.

A very nice puzzle to work on one's 5-whisper colouring skills. Cheers!

SECOND
a solid exercise in intermediate techniques for GW puzzles. can be solved most efficiently using just 2 colours (+ neutral = 5), and marking the 4 critical candidate pairs.
because these techniques can be fully explained to any noob in <15 min, this puzzle qualifies as "approachable"
