Try a smaller practice puzzle first!

This is our revision of the original Foghqwhgads, which begins the same but takes a different path after the first handful of digits. Please see the solution guide for the original if you require help with the break in - I'm afraid you're on your own for the rest of this one though!

We made this second version for three main reasons: it avoids a somewhat bifurcatory step that existed in the original; it maintains a more consistent difficulty where the original had a few uncharacteristically "easy" deductions (sorry not sorry!); and it removes all overlapping lines and therefore the ruleset can become much more concise.

Everybody to the limit



Normal sudoku rules apply.

"Fog of war": The grid is covered in fog, which will lift to reveal clues as correct digits are entered.

"Filler": Shade some cells such that each digit in row 1 (top) indicates the count of shaded cells in its column, and each digit in column 1 (far left) indicates the count of shaded cells in its row. E.g. a 3 in r1c8 indicates that there are 3 shaded cells in column 8.

"Yin Yang": All shaded cells must form one orthogonally connected region, as must all unshaded cells, and no 2x2 square can consist of only shaded or only unshaded cells.

"Balancer lines": Along balancer lines, the sum of the digits in shaded cells equals the sum of the digits in unshaded cells. The lines do not branch or overlap.

Lösungscode: Row 9 (bottom row)

The first two puzzles really help me to solve this one,so I don't think this one is very hard

Crazy hard, amazing rule set, and brilliant logic throughout. Felt like I had to work hard for every deduction. 10/10!
