Two rules today. Global Entropy and Arrows. There was some mixed feedback on difficulty, so I've set it at 3 stars, but you may find it easier than that! Thanks to all the testers. Comments are greatly appreciated and enjoy!
Puzzle: 3 States of Matter

Normal 9x9 Sudoku rules apply.

this will be easy enough for anyone experienced with global entropy procedures. since those procedures can be taught to anyone within 15 min, the difficulty qualifies as 2/5

A few easy spots mixed with a few tricky spots, but either way a fun solve!
