Darwin72 that is a really nice idea
can be done , almost with little expense
but the problem is to make it work with Metal
else it would be a normal site to bet money or BTC
i tried to get Metal on directbet.eu they are doing bet with other crypto
they responded that Metal has low market cap maybe they meant low daily exchange
i dunno.
making a link from the wallet or the site of Metal
to make private bet with Metal coin would be good
it need some arbiter to make the game fair if possible
or waiting to make Metal coin use
supernet - blocknet when private bet can be made.
for now can be used a platform like Gamerholic (works with PC , playstation and xbox):
https://www.gamerholic.com/#/esportsthey have a system with arbiter so cheating is likely to be discovered.
Their announcement to add game :
"Want your own game on Gamerholic? The Solitaire game was added by a site member, he'll make at least $0.05 each time the game is played competitively. Head over to codecanyon.com, buy an HTML 5 game for less than $20 and we'll plug it into the platform for you for a small $75 installation fee. Pay in bitcoin or gamerholic coin. Let us know the game you'd like to add BEFORE you buy."
i don't know if it will be possible! But i think if yes it will be very nice! Do you remember you all, when we could play chess with messanger chat? Messanger it was an application made by microsoft like skype. Is possible to find soursecode for wallet that you could play chess with people that have wallet open,i say chess but could be any small game , it make any sense what i say? Sorry for my english...
Of course to play you have to bet some coin
