Full rules:
Schrödinger Sudoku rules apply.
Regions must be determined by the solver.
Each row, column, and region must contain one complete set of the the digits 0-9 without repeats. To accommodate this, some cells (called 'Schrödinger cells' or 'S-cells') may contain two digits.
Each row and column in the solved grid must contain exactly one S-cell.
There is no restriction on how many S-cells a region can contain as long as the region has exactly ten digits.
Circles contain a digit which counts the number of cells (including themselves) in the surrounding 3x3 neighborhood which belong to the same region as the circled cell. All possible circles are given.
Squares contain a digit which counts the number of regions (excluding their own region) which have cells in the surrounding 3x3 neighborhood. All possible squares are given.
In the case of a circle or square on an S-cell, only one of the digits must satisfy the constraint, while the other digit is unconstrained by the circle/square.
Arrows on the border between cells point to the S-cell in the corresponding row or column, and the digit in the cell at the tail end of the arrow indicates the distance from that cell to the S-cell. The distance must be a positive number. All possible arrows have been given.
Blue lines are Equal-Region-Sum lines. Each line visits at least two regions, and the sum of all the digits in the cells for each pass through a region must be the same for any given line.
Challenge Accepted!
My solve time was comparable to yours, though I was focused on finding the regions ahead of the digits where possible. Probably not my smartest decision to make this my first S-cell puzzle ever, starting at midnight.
I'm sure there won't be any consequences for my choices.
Thank you so much for streaming this solve!
It was a ton of fun, and chat seemed very enthusiastic too!
This was a mind bending journey and joy to watch for the full 3 hours. Good job all!
Thank you so much, I'm glad you enjoyed it! It is one of my favorite solves of all time!
I guess you could say the blue region was the key to the whole puzzle.
(because it looks like a key 👀)
Oh that's an interesting read, I always see that particular region shape as a submarine popping out of the water, but I might go for key now!
