Free multiplayer football game in your browser
Two teams of players, a ball and a pitch, in the browser you already have. Nothing to install and no account to make: somebody opens a field, sends the link, and the room plays. Free to play and free to host.
Every field is a stadium somebody built on a shared map, and every stadium has a centre circle, four hoardings, four stands and a wrap around the outside that anybody can sponsor.
Every surface opens at $2 and is held for 30 days. Bids rise in $2 steps, a higher bid takes the surface at once, and what the last holder paid stays with them as credit to bid again.
A field is free to play and free to host. The money in this world is the advertising around the pitch, sold by open auction rather than by a rate card, and the sponsors board lists every surface and what stands on it.
