Well Relax slots are known for its volatility though but Deadwood from No Limit City is probably the most volatile slot ever.
Agree, I play once and banned that game from my slot game.

Lol, I feel you, i have been getting lots of reds (loses) on this provider, probably due to its game being high to extremely volatile.
Not every game is the same, some games for example give you a small return even when you lose on slots, like for example you get 0.5x back and lose half of your wager and rarely ever hit zero, but you do not get a huge amount of win. And some games are like you lose almost all the time but when you win you win like 999x and that is how you take it back.
Games are quite different from each other here, the odds change a lot and that game could be a lot more volatile than you want it to be. This is why I think it is quite obvious we should not be focusing on something that doesn't make us happy, if you feel bad about one slot and you do not want to gamble there, there are a lot more other places that you could gamble and have fun with. I do not play on the same slot for way too long, I just skip around and pick the ones I will feel better about and basically rank them for myself.
