Menderbug

🎶 It's just another Mathsy Monday (ooh-oh) 🎶
One of the more popular partial Latin squares genres, Japanese Sums, finally got tool support on pzprxs a couple of weeks ago! Which is great, because the genre is long overdue to appear on GAPP again. We have featured it only once before, almost three years ago: Archive: Friday, 1 July 2022

Rules: Shade some cells and place a number from the range given outside the grid into the remaining cells so that no number is repeated in any row or column. Numbers outside the grid indicate the sums of the numbers in groups of consecutive numbered cells in the corresponding row or column, in order. Sums must be separated by at least one shaded cell.

🖥️ Interface tip: 🖥️ On PC, you can use Q/A/Z to place a dot (marking a cell as unshaded without specifying a number) and W/S/X to shade a cell.
