Anyway, speaking about "challenge" some user bitcointalk talk about this topic in the last few posts. Can we know all challenge created by stake in a single view, because I play some slot "Akh of Anubis" there has some challenge from eddie with prize 1,000$ in BTC for the first person who hit x3,000 with minimum bet 0.2$
Do you mean to see all the active challenges? If so, you can see it here:
