For third deposit at Slotsmillion casino I got 25% bonus plus 20 free spins. 25% is not big increase of my money, but it is good, wagering requirements only 35x bonus, so it will not be very hard to complete this bonus and make some profit. Also 20 free spins credited next day it is not big deal of course, but it is cost 5 euros in money if you will play twin spin, and winnings can be spent on any other slots, so i think it is not so bad bonus.
I deposited 20 euros, and got 5 euro as a bonus. Wagering requirements was not big, so I decide that I will not pla doa or other slots which can eat money or can take money very fast. First slot I decide to try was fruit shop,with 0.30 bet. I do like that you get few free spins on this slot usually and fast, and it is just interesting to play this slot. Unfortunately things was not good for me, and after losing 10 euros I switch to Gonzos quest. My friend Gonzo make me a gift- give free spins on third spin, bet size was 0.40. Not so big winnings, but hey, plus 50 euros to my balance. Then I played evolution a bit, then tried few more Netent games and achieve 100 euros balance. WR still was not beaten, and I decide to play Starburst a bit. 100 spins at 1 euro bet size- and 110 euros finish money. Request withdrawal and get paid on next day, without docs, which is great. With twin spin free spins did not win anything decent, was about 3-4 euros, and then DOA was happy to take it back.
