Good problems are even better with company.

This is an early, local preview. Create a room, open its link in another tab in this browser, and try a session together. Room chat and sample progress update between those tabs.

Links do not connect different devices yet. Networked rooms, WebRTC, accounts, and ranked judging are still being built. Sample checks are public practice checks, not ranked verdicts.
