Nowdays there are many dice websites with great promotions and offers. If I were you, I would take care of template at first. You offer 100% bonus, that's attractive for new players but is it logical to request 100x wager for claiming that bonus? There is 100x higher chanse of losing whole money. Also you have to research other casinos history, remember duckdice, they got red trust because of their bad bonus system.
Actually 100x wagering requirement is still low compared to other dice site that has the same promo. Duckdice for example, their wagering requirement was 110x IIRC. Pocketdice also have similar bonus and has the highest wagering requirement (700x). So for a new site with 100x wagering requirement for the bonus is actually good enough especially if there is no additional terms such as the minimum payout that counted toward wagering amount.
Good to see it is now reduced to 50x, need to try this as it looks like a +ev for players who take the bonus but of course anyone who want to take the bonus should read the full details of the terms and conditions.
