Hello dear friends from BTCTalk! Chris here, we have conformed a small team of developers and already produced our first BTC Game.
Is there any 1 VS 1 Poker in BTC online?
If so, would you be interested in alternatives? is there any other Player vs Player game that you would like to support?
Player vs Player is not really popular IMO in the crypto gambling world. Sites that launch PVP games like coinflip and such are just wasting resources.
You ask about heads up poker as well. Currently there is SWC which has heads up poker. You can also deposit crypto in sites like Americas Cardroom, Blackchip Poker, and True poker(all the same site, just different skins) and play heads up.
Pretty sure there are other sites out there as well, but none come to mind.
