The Radio Games Matching Service (RGMS) is a contact confirmation and awards service for amateur radio, run as a nonprofit public service. Upload an ADIF file, or let your logger do it, and your contacts are matched against everyone else's. No certificates, no desktop signing tool. Only matched contacts are ever visible, so your log stays private.
Upload a log from the site or the API. Matching is deterministic and the rules are published: same band, same mode group, within 30 minutes. There is nothing to install, no certificate to renew, and nothing that stops working when you change computers.
Most award programs show progress only toward what you have already started. Radio Games shows progress toward every award, so the awards page doubles as a map of what is left to explore. New operators earn real awards within their first few contacts; experienced operators get tiers that take years. Stranger awards (palindromic callsigns, contiguous grid squares, contact streaks) are planned for when everything else is done.
Logging software connects over the API with OAuth2 scoped tokens. Your logger can push contacts and pull confirmations without ever holding your password, and you can revoke its access without changing anything else.
Radio Games is operated by Radiofun, a Washington nonprofit, and the entire service is open source: the site, the API, the matching engine, and the award rules. The core service will always be available for free. If you don't like a matching rule, the code is there to read and argue with.
