I'm looking to implement a very similar experience as Blackout Bingo app. I'll need an HTML5 75 ball bingo game with the options to have different power ups (add more time, select a number from the card, etc), to play 1 on 1, tournament and that. This has to connect to a backend with a provably fair scheme for the games.
I'm open to do this as a native iOS and android App, but I think the HTML5.
Full specs will be provided once we talk.
