Not trying to distract solvers from this forum, since there are plenty of different types of puzzles to try here.
I tried the link to the VX Puzzles today. That site has 5 different levels, ranging from (Exremely) Easy to Expert; the link goes to whatever is the most recent Expert level puzzle.
This is the one that I reached today. It's about the level of an average MeanDoku NC, so anyone who has done those shouldn't find it too difficult; remembering that any pairs of cells not marked as V or X is like applying NC in a MeanDoku NC. I needed to use some short forcing chains to make a few later eliminations and placements but they were easy ones which I could do in my head, so I didn't write a walkthrough.
How about it
enxio27; it only needs mental arithmetic deciding whether pairs of cells total 5, 10 or don't.
