how long would we get to complete the 6× bonus wagering requirement? Are we allowed to place parlay bets to meet the minimum odds requirement? Or does it have to be a single bet with minimum odds of 1.60×?
Trofo missed this part, so yeah, Parlays are allowed for the for the 1.60x requirements, and you have 30 days to complete it..
To buttress on Trofo's point, if you have no issue with KYC then, they're indeed one of the best imo too, I like their market options and the odds aren't bad either, I actually do prefer to use them for any of my bets on tennis, also I would say I was able to turnover some of the prizes last season to the tune of several hundreds of dollars without any problem.
Personally, I think the requirements for unlocking the rewards are a bit difficult.
I actually don't think so, 6x for 1.60 odds and you get to keep all your winnings should be considered a great offer, that's for anyone who does place bets regularly,though, especially when you consider that parlays and betbuilder are both allowed.
