With a voucher card for Runescape, which you can easily buy on coinsbee.com with one of over 50 different crypto currencies securely, anonymously and at lightning speed, you can become a Runescape member and play the game in the main version. This game membership is offered in different time periods from a few weeks up to a whole year (the longer the cheaper).
By the way, a new Runescape version for Smartphone and Tablets will be released soon. This means even more fun on the road.
