This puzzle has been in the works for an extremely long time, and I am thrilled to finally be able to release it. Hope you enjoy solving it as much as I enjoyed making it!
Typically, Line constraints only interact with digits on Sudoku Cells, but in this puzzle they also interact with digits in Quad Circles.
In this example, the cell highlighted in blue is connected via a red parity line to a quad circle containing the digit 1. Because 1 is odd, and quad circles count as values along parity lines in this puzzle, the highlighted cell must be even.

what was that??
I sooo wanted to play this sudoku, the screenshot looked too tempting to let it pass..
So I opened the link and stared at it until my eyes ran dry and started to shrink inside their sockets...
I passed, I am NOT ready for this!
But I couldn't the mesmerizing image... I MUST
Ready or not...
I think the app counter rolled over or I forgot to unpause the game after my fourth or fifth cup of coffee.. IDK, but that thing is a beauty to solve.
Don't get me wroing, I found it terrible to scan this beast, I lost more track than the north pacific railway ever laid down but it was rewarding to claw my way through.
The way the 8x8 provided a shimmer of light in this tunnel of despair was just great.
luckily the endgame for my colouring attempt was pretty straight forward.
IDK if it was the hardest puzzle I ever solved, but it's certainly one that took the most effort AND more importantly one of the few that -being intimidated or not- I simply HAD TO solve even after shying away at first.
THANK YOU!!
