Open a room, and deal.
Add a friend by their player code, open a private room, and play any of the four games together. There is no chat to moderate and nobody to wait for.
There is no email address and no password. A player code is your whole identity, and you can share it with whoever you want at the table.
Ranked play matches you against someone near your rating and moves you through Bronze, Silver, Gold, Diamond and Legend across a season.
Online play and the ranked season switch on when One Table launches. Everything else plays offline, with no connection at all.
