David Murdoch's side top the standings after the hard-fought win and look to be in with a very good chance of moving into the semi-finals.
After a cagey opening, Britain fell 2-0 behind in the third end.
But they held their nerve and took a 5-2 lead by the seventh end before fending off Germany's late efforts.
Every team will have nine round-robin games, with the best four moving forward to the knock-out stages.
