I have played a number of times in types of slots that have high volatility but have never produced a win.
How many spin exactly? I spend more that thousand of spin on high volatility slots but same as you, I didn’t manage to land on any massive win. I usually play medium volatility slot game to have decent win with just using a normal bankroll. Don’t chase high volatility slot if you can’t afford to lose small bankroll. This type of slot is savage for beginners.
I tried high volatility slots for around 400-500 rounds and no more because there used a lot of bets for me so I didn't dare to decide to take more spins.
I know this type of slot is difficult to win, even to be able to get a return on the capital spent is difficult.
That's why I chose to stop playing high-voltage slot games.
Yes, it's true that playing high volatility slot games like Wanted Dead does require a playing strategy and quite a lot of funds because this type of slot is very difficult to win and can even make gamblers who play there lose all their money without getting a win in buying bonuses or spins normal.
Playing slots with the intention to make money usually don't end up good and its a bad strategy due house edge. Instead, people should see it as an entertainment (and gambling in general) as that's what it is. I used to be a regular at brick and mortar casinos (not so much in the last few years) but I never went there with intention to make money. Instead, it was more about hanging out with my buddies and having a couple of beers while playing slot machines.
Playing slots with the aim of making money will end badly, that's right, friend, because expecting some money from gambling games is just a dream.
But when a Wanted Dead type slot that has high volatility is played just for fun it will also end badly because this type of slot game is difficult to win and has a fairly high minimum bet in my opinion.
If you're playing slots just for fun, it's better to play pragmatic slots that have a fairly low minimum bet, such as Gates of Olympus, so that it saves you more money and if you're lucky, you can get quite a lot of multipliers.
