If you win from the free spins? Normally anything you win from the free spins needs to be wagered 30-50x based on the rules of the site. Once you meet the wagering requirement then you are allowed to withdraw it the winning although some sites has max winning from free spins but it worth to try as you do not risk anything from free spins promo.
The condition to achieve is after you play the free spins not before you play the free spins. In this case, you'll get 25 free spins just for creating a verified account (email and phone number) at Fortunejack IIRC.
I see. That wagering requirement should be to minimize the chance people can easily withdraw through free spin.
They verify their account only by email and phone number? Seems it can be abused by multi-accounters
