Play on SudokuPad
Place the digits 0-9 without repeating in any row, column, and box. 0 must appear in every box, but never in a cage. Since there are ten possible digits, each box will miss one digit. There are an equal number of low, medium, and high digits missing from the grid.
Global Entropy: Every 2x2 box must include one low, medium, and high digit (123, 456, 789). The final cell will be a 0 or a digit from any set.
Digits in a cage cannot repeat and sum to the number given. Each cage has a unique set of digits.
Solution code: Column 2 top to bottom

Almost two hours but great fun! At least after rereading and starting to use all the rules :). Thanks!

Hi everyone, mild spoilers ahead.
I've created global entropy puzzles with zeros recently, but here is a new version that incorporates the missing digit concept. I'm not sure you can find an easy path without guessing, if you just start coloring. There is another approach that I would suggest using which will give you a head start. Good luck!
