Nono Blocks Formula

I like to play this little game on my phone when waiting in a waiting room. Not boring. It starts to get harder when density goes down but not too hard ☺️

Love this puzzle. Some rounds have multiple solutions so it doesn't always wrap and go to the next when all rows and columns are lit up green and all boxes are checked. In those cases, I wish there was a way to check for errors. Also, there's no way to reset the same layout to start it over. If you hit the start over button the level number stays the same but it actually gives you a different puzzle layout to solve. Otherwise happy as a clam.

Could use a few simple features that would greatly enhance the experience….add tap and drag to select multiple blocks at a time, add dark lines in multiples to fit the board perhaps in groups of four as each side is divisible by 4, this would make it easier to identify where you are when counting and lastly, write a little blurb on the side to inform as to how to select, deselect and make blank.
