You'll win but it won't be as significant as the good amount that we usually get from betting with certain matches and high odds. It's like getting something for free and you don't expect to get the best from it.
Dear it is free spins. If you think free spins give bigger amount so it is not possible.
It is possible but there is only a slim chance. Like triggering a bonus round during the free spin and hitting a max win. After all in slots, it is luck that matter not where the bet is coming from. May it be a normal bet or a free spin, if you are lucky, you can get a decent amount of winnings from free spin.
In betting you bet your amount than you get the reward. In this if you win than you will get your amount.
Isn't it the same with free spin? The good thing with free spin is that you don't need to spend fund from your bankroll to spin. The downside is that many free spin has wagering requirement before we can withdraw them.
But free spins are free and in this case you will never get big amount and not sure that the withdraw will be possible or not.
AS I said it all depends on how lucky you are.
