Nothing bad happens. Rounds run entirely on RojoBingo's servers — your connection just displays what's already happening, it doesn't drive it.
Are my cards still in the game?
Yes. Every card you bought stays in the round, and the server checks it against every number called whether or not you're watching. Auto-daub isn't something your device has to keep up with — it's simply how the called numbers look on your card, so there's nothing to miss by stepping away.
Could I lose a win by being disconnected?
No. Wins are confirmed automatically by the engine the instant a card completes a pattern — there's no "call BINGO in time" window to miss.
What about my credits?
Safe. A dropped connection doesn't touch your wallet — your balance is exactly what it was when you bought in.
How do I get back in?
Just reopen RojoBingo and rejoin from the lobby — your cards and the round's progress load right back in.
