Some people confused on the free spin and buy bonus especially on discussion like this.
I can’t understand how anyone who have played slots doesn’t know the difference between free spins and bonus buy or the bonus feature!
Free spins are nothing but regular spins and as the name suggests they are for free which gamblers get as a reward or bonus. Whereas, bonus buys are when you pay exra money to instanty trigger the bonus feature.
Probably because on bonus feature some slot game indicates the number of spin as “free spin”. Because bonus feature can be achieved using normal spin which means all the extra spin are considered as free spin.
This comes the confusion on terms being use especially for those slot players that is not playing frequently.
Maybe for those who don't play slot games they will be confused, but if you often play slot games, then you should be able to distinguish between free spins and buying bonus features.
To put it briefly, free spins are spins that we can get when playing by pressing the spin button and getting the conditions, usually scatter. While buying bonus features we have to make a bonus feature purchase which will later cause free spins.
