This is not that puzzle.
This puzzle serves as a more easily handled example for the main event to follow.
Shade some cells and fill all unshaded cells with a digit from 1-6.
No digit may repeat within a row or column.
Each cage contains a set of all the digits and a shaded cell.
Clues outside the grid give the sums of connected groups of digits in the row/column in order.
A ? may represent any digit from 0-9 except 6.
No number may begin with 0.
Inequality symbols between clues show that one clue is less than the other (a < b means that a is less than b).
For any row/column either all or no clues are given.
Happy solving! Here you can solve the puzzle online:

Loved this! Don’t shy away from the main event… yes, it’s a Satan puzzle, but it’s the good type of torture :)

I enjoyed it a lot. Should have read the rules more carefully because I totally missed that a ? couldn't be a 6 and was wondering how the end was ever gonna resolve
