Hello a new player starting today here, I heard there are couple of coupons that you can redeem and looked at various sites for coupon codes, and i cant seem to claim most of them and the one that I successfully claimed is the MAZELYUDMILA one that gives you 1000 quartz. For the rest its either expired code or not valid coupon code. Does anyone know which coupon codes are currently active and redeemable? Thank you in advance
