This is reload monthly bonus, which available not for all players, you can get this bonus only if you at least on second stage of bonus program, and if I remember correct you need to wager around 1.000$ to achieve this level, and only after that you can use coupon vipmatch. It is 100% bonus on deposit, which have 30 x bonus wagering requirements. Nothing special, but still nice offer, to play 300 shields ;)
I made 30$ deposit, and to redeem bonus i was need to enter coupon code in cashier, and then made deposit. If you did not make this, you will not be able to get bonus. I decide to play 300 shields slot, because I am VIP because i am can! :D Of course I decide to play this slot just because I love it, and most profitable sessions for me in this group was of course when i hit big at this awesome slot. I decide to play with 0.50 bets, and like almost with this slot, experience can be awesome, just good hit something like x 500 total bet, or bad experience when you lost your deposit quickly. Unfortunately this time I had third experience, and just lost my deposit and bonus without even able to hit freespins feature. Sometimes this slot can be real monster.
I rate this bonus with 7 stars, it is better than most welcome offers, but nothing really great. But of course since it is another bonus, I think it is need to take it .
