On level 9524 i got stuck in a loop and the fish kept going on and on for 20 minutes

I did as well and needed 2 of the black spiral squares to complete the level and even though I had to wait about 5 min for the fish to stop not once did those 2 squares come down which I find ridiculous!!! I get there is an algorithm but if those columns keep spinning down and nothing, not one of those squares that are supposed to drop down comes down, is ridiculous. Gonna step away for a bit as it seems not matter what it’s rigged to just get me to spend money when there was no way that should be happening.
