Rules
Click on cells and fill the board with white or black circles. To choose the correct color follow these rules:
- No more than two of the same colour next to each other
- Each row and column must have the same number of coloured circles
- In the non-Plus version no two rows or columns must be the same
- In 'Plus' a '=' symbol between two cells means these two cells are the same
- In 'Plus' a 'X' symbol between two cells means these two cells must be different

Thanks for that.
The only thing I would like to see is that the check would only shows IF something is wrong and not showing WHAT is incorrect on the field.

And so, my request: some harder puzzles that use these (Weekly "Extreme", perhaps?). Also, no Hint button for these either.
Also, a fun combinatorics question for anyone reading this: how many possible Binairo solutions (i.e. solved grids) are there for a given 2n by 2n grid (NB this does not even begin to touch on the number of possible puzzles...).
I will have a look at the code again, maybe there is something I missed.
I do know that the regular Binario should have the rule about no rows or columns being identical but that this is not a rule in Binario+. By that I mean the generator enforces the no-duplicate rows/columns (I think!) but it is not a necessary rule to solve the puzzle. It’s very niche so I don’t think people will be up in arms either way
Not sure how to turbo charge the creator to make extremes. I don’t think the spectrum is wide enough or has a long tail like Sudoku. Or maybe I can change the scoring to do that.
Is a good combinatorics question!

This reminds me of the many like puzzles in this game called Islands of Insight (https://store.steampowered.com/app/2071500/Islands_of_Insight/), where many different rules can be applied to make many different kinds of black-and-white puzzles in this game's Logic Grids.
For example, Binairo can generally be coded in using a couple of "Don't make this pattern" rules and some Darts.
Anyway, back to the webpages. For those using a mouse: left-click to add black, right-click to add white. Both options cycle between black, white, and empty upon subsequent clicks. I mention this because these precise details aren't exactly in the Rules. Also, in Islands of Insight, one could simply left-click to add black, and instantly right-click to change it to white without the need to erase a cell (or vice versa), and it would be nice to have that behavior here as well.
