One Too Many (Japanese Sums, Tiny Cave)
(Published on 2. March 2025, 14:43 by .proxz14)
Japanese Sums are my favourite genre, so it was inevitable that eventually I'd have tried making one of my own. I decided to add a little twist to it, hope you enjoy!
Rules:
Normal Sudoku rules apply: Fill every row, column, and 3x3 box with the digits 1 to 9 once each.
Japanese Sums: Place digits from 1-9 into every unshaded cell such that no digit repeats in a row, column, or a 3x3 box. Clues outside the grid are Japanese Sums clues, which indicate the sums of the connected unshaded blocks, in correct order. For each row or column, either all or no clues are provided. However, one of the clues in every row/column is fake and doesn't exist.
Cave: Shade some cells such that each unshaded cell is orthogonally connected (creating the cave), and each block of shaded cells is orthogonally connected to an edge of the grid (the walls). All clued cells inside the grid are part of the cave, and indicate the total count of unshaded cells connected vertically and horizontally to the clued cell, including itself.
Tiny Cave: There can't be a 2x2 square anywhere on the grid that consists of all shaded or all unshaded cells.

the break-in was quite complex (given that i solved this without the question marks), but from thereon it flowed very nicely :) nice puzzle!
.proxz14's response: You are tempting me to remove them again :)
