You may not have to wager the winnings from free spins but you still have to wager the initial deposit 3x or even 5x. And chances are you will lose some. Also lots of casinos are now fixing minimum withdrawal amount to €50 or higher so even if you get these 50 free spins from €20 deposit you have to still play your initial deposit.
@onlinecasinooptions Hi there and welcome to the forum.
Unfortunately for me, my country is forever restricted from anything wager-free, so I can only watch and weep! 😜
