Low or high volatility slots?! High-volatility slots are way more interesting than low-volatility ones... at least for me. And from my experience, it's almost the same! I played low-volatility slots and lost a lot without any big wins or hitting a bonus round (or I won a bonus round that gave nothing), and I played high-volatility slots and won a lot after a few spins. I feel like it's not about the volatility, they can present any numbers there, it's about pure luck!
You can be right in that, I don't play a lot on slots anymore. I just had some bad experiences with high volatility slots that depleted my bankroll quickly and I remember one time, I was spinning a high volatility slot (after seeing some youtube videos) and spun about 30 times without a single win lol. My favorite slot is Miles Bellhouse and The Gears of Time from Betsoft as I tend to get lucky on that one most of the times.
I myself am not very interested in slot games even though I have played it 2 or 3 times because I was curious to try, but after I tried to play and observe it, slot games are indeed difficult to win, especially getting a jackpot, only those who have big luck.
Try to play on Roulette because the game can be guessed and do some research to place the bet on the right number.
