** TODAY'S PUZZLE **
This puzzle is SO surprising. The ruleset seems pretty normal and yet the absolute magic that Kennet's Dad has conjured up here is remarkable. The sudoku is called Diaeresis 2.0 (we don't know why) and this one is definitely memorable!

Play the puzzle at the link below:

Rules:
Normal sudoku rules apply. The grid is mostly covered in fog; placing a correct digit removes fog in surrounding cells. No guessing is required. A red "X" indicates a product square: a 2x2 region of cells where the product of the digits on the negative diagonal equals the product of the digits on the positive diagonal. A blue "X" indicates a sum square: a 2x2 region of cells where the sum of the digits on the negative diagonal equals the sum of the digits on the positive diagonal. Digits in cells separated by a white dot must be consecutive. No rule is subject to a negative constraint.

** NEW STREAM COMING UP TOMORROW **
We're going to be solving puzzles from our 600k Subscriber Pack on 1 October at 10pm UK time. We'd love to have your company. Link below:
