Can someone explain to me why my solution for Puzzle 25 is not valid? Am I missing something? https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=3398177823

Is there meant to be logic/reasoning to this stuff or is it just "keep arranging the equations until it starts the next level"? because i feel like there's usually 1 maybe 2 tiles you "must have" but then the rest is just trial and error?

Can you please add an option to disable the wave effect? It's really bloody annoying.

Is anyone else experiencing this? If I make a single mistake, it backs out of the puzzle to the selection screen. I always go slow and try to get it perfect before actually making any choices, but it's really annoying having to start the same puzzle all over again when it happens....

Edit: game update makes the below moot :-) Stream of consciousness post, I solved my own question while writing it out, but I sat there for a bit scratching my head, so I'm wondering if the tutorial level might need a better method of conveying the info...
