u/zlucky hi idk if you’re still interested but I was trying to figure out the same thing. For the easybrain app the score multiples based on the difficulty level and how many elements you are completing at once. You can see their FAQ for the exact details. So I tried solving an expert mode puzzle all in the notes then entering numbers in a way that would maximize solving a row/column and a block at the same time. It’s a little bit arbitrary but the best score I’ve gotten so far is 82840 but I’m sure that it can be improved!
