*** TODAY'S PUZZLE ***
Mark gets Simon to open tonight's puzzle during the video, which normally means there's something very unusual about it... See for yourselves! It's called Eroteme, it's by Crusader175 (Alaric Taqi A.) and it's mad and clever!!

Play the puzzle at the links below:

https://sudokupad.app/9t6sdzcr8b

Rules:
Normal 6x6 sudoku rules apply. Digits may not repeat along the blue diagonal. Circle one cell in each row, column, and box. Digits may not repeat in circled cells. Clues outside the grid indicate the sum of the first X digits in the corresponding direction, where X is the digit placed in the circled cell in that row or column. A question mark may represent any digit from 0 to 9, but for double digit numbers, the first digit may not be 0.
