Do you mean not even single scatter in 150 spins? Frankly I cant believe it, but it is possible although the the chance to not hit even a single scatter in 150 spins is so low. What slot you are referring to? I have never experienced such bad streak without a scatter, a scatter should be easy to come but scatters (3-5) as a requirement to get the free spins is harder.
Not even one scatter Symbole in 150 spins seems very unlucky. Not sure what the chances are up get a scatter but it's definitely higher than than in his last session. Pretty sure if he would play another 150 spins he would get all the scatters he missed out previously. I not really playing so much spots lately but I tend to always get a some bonuses. Free spins are usually programmed into the games and come after a certain number of spins. For a casino having free spins for slots is a good way to keep players engaged and interested for more.
