A warm light. A different way home.
A battle courtyard, warm hangouts and an archive inside the mountain. Climb to the Hall of Records, catch the Skyline Line, or come home by the water. Welcome to WhoWins Crossroads.

Early prototype · free in your browser · more on the wayAcross Worlds is WhoWinsAI’s free 3D world, played in your browser on a computer or phone with nothing to download. It is an early prototype: walk a lantern-lit town, ride the Skyline monorail, head over to Home Island to build and decorate a place of your own, then cross the causeway to Volcano Island, where any two characters can fight it out in the arena.
At the volcano console you pick any two fighters from the WhoWinsAI roster of 700+ characters from Marvel, DC, anime, games and more. The same engine that decides every battle on WhoWinsAI.com settles the fight from canon feats, powers and weaknesses, and the arena acts out its verdict: who wins and how. The same matchup always gives the same result.
Volcano Island is still growing, more characters are getting their own 3D looks, and the town’s halls (the Battle Hall, the Hall of Records and the rest) will soon fill with character data from the site.
Is it free? Yes. No download and no account needed.
Does it work on phones? Yes, with touch controls. On older devices, choose Low detail in Settings.
Just want the fights? Battle Island is the arena on its own page: quicker to load, with a Record mode for clips.
