Since you mentioned Simon Tatham puzzles there's a js version here[1], but it really just isn't quite as good

(if I were to nitpick, for large grids one might want to make the separating line a bit thicker every 5 blocks for faster counting, and repeat numbers at the bottom/right -- but at the size the examples are in neither are needed)

(BTW you didn't mention for overlapping but there's a nice trick: just try from either end, count how many cells are leftover, and take that off the starting side of each block)

Sorry, cannot edit the grandparent post. I copied that invalid link from safari's url bar, perhaps Google Play store did something unexpected with URLs.

"When there are two or more numbers, this means there will be two or more groups of filled cells."

Is the "group number" the size of the first group? That seems to fit the tutorial example where (1, 2) = (., x, ., .) and (2, 1) = (., ., x, .).

Thanks for making this - I've stumbled across these puzzles but never took the time to try one.

Each number specifies the size of the corresponding group. E.g. numbers “5 4 7” would mean: “three groups of filled cells, first group will consist of 5 cells, second will consist of 4 cells, third group will consist of 7 cells”.

Have fun and I’m happy to hear that this is useful!
