I used to grind Dragon Tower on auto for hours but lately I found a specific slot called Gates of Olympus that actually gave me a bigger hit rate when I bet under 50 cents, weirdly enough it felt less punishing than chasing multipliers on Plinko.
Mine was vs 56 suited which sounds absurd but they were the short stack tilting off. Flop came 2 3 4 and I didn't even see the straight until the chips flew left, pure vacuum feeling.
