I thought that the site has died already last year when there was no more updates here on their official thread. Anyway, why you did still play on this site while they have no active representatives on this forum?
Afaik it is owned by same person who manage dicecoin.io , and surprisingly the rep of dicecoin.io is also not active anymore here (last active almost at the same time time with the rep of cryptogames.io).
By the way, hope you did not make a big deposit there as I think there is no ways for you to get your money back.
