What is so special about slot games? Words are not enough to explain it to you bro.
I'm a pure sports bettor but addicted to playing slot games in some cases. Why? You need to try for yourselves. It's not just about luck but the experience of thrill especially if you trigger the multiplier. Of course, be responsible and learn to stop the moment you hit that.
I'm a fan of buy-in anyway as I'm tired of manual spins.
I'm sure you just want the thrill with doing a buy-in, I'm not interested in being with a buy-in because the manual is more reliable, but I understand that different people have different ways.
Honestly, in terms of reliability and chances of winning, I don't see any difference between the manual mode and buy-in. The risk is there are both.
It's just that, and I already mentioned it, I'm tired of doing manual spins and even using the auto-bet won't make me feel thrilled and excited. By buy-in, there's already an automatic free spin and my instinct always tells me that, this is it. Of course, there are losing experiences but I really prefer to buy in because that's where I always hit good multipliers.
Tip: Choose slots that have a buy-in feature where it gives more free spins and good multipliers. Not saying it will increase the chances of your winning but we do like more free spins right? I literally end up checking different slots, trying their buy-in, to feel the experience, before choosing that slot game.
Anyways, this is regardless of the game provider.
