The arcade
Six games.
Real opponents, no sign-up.
Pick anything below and you're dropped into a queue. Someone else taps the same button, the server pairs you, and the board is live. That's the whole business model.
How multiplayer works here
Matchmaking
Tap play and you join a queue for that specific game. No lobbies, no links to share.
The server is the referee
Every move is validated server-side, so the two boards can't drift apart.
Rooms expire
Walk away and the room cleans itself up. Nobody is left waiting forever.
