In fact, staying on high stake slots are not good luck for me. Sometimes it causes me stress. So, I lean towards penny slots most of the time while playing. In the case of roulette, always I limit my bet from 10 cents to 10 dollars, it gives me so much joy and doesn’t have the fear of losing lot money. 
Pretty damn sure people tend to go for penny slots rather than staking high , unless if they are in anger which could leading you to go allin in a couple of spins or even just in a single spin! I've done it before. Lost too much and don't know how to get back that much amount of money then seeing a slots machine bet history of mine , there's 20x winning with 2 cents stake damnn i thought i could have the same result as I've been too desperate, making 50 bucks bet in 2 spin each .. gets $4 in return , what a frustrating day it was.You better stay for the penny slots and eyeing hunders/thousands multiplier , that's the best advice in slots!
