Yes — you must provide a handle on the judge (Codeforces/DMOJ). We use that handle to automatically detect your accepted submissions.

Not currently. Matches are created by a host and the host shares the match link with participants.

Submission detection may take a few seconds. The system polls the judge periodically and will update tiles as soon as it confirms a valid accepted submission.

Give it a moment (typically 10–30 seconds). If it still doesn't update, verify that the handle in the match matches the handle you used to submit and that your submission shows as accepted on the judge. Note: the judge may throttle its API during official contest rounds — avoid starting matches during major contests.

If Replace mode is enabled, replacement usually takes a few seconds. If the tile remains unchanged, try refreshing the page. If it still fails, the host should check server logs or contact support.

Match creation can take time depending on the number of handles and the size of the problem pool. It may take up to 30–40 seconds in some cases. If it takes much longer, check your network and server logs or try again.
