In a report by Anjel Van Slyke and Connal Hughes about the Museum of Soviet Arcade Machines they've got a video of Танкодром (Tankodrom / Tank Training) which is some kind of open-field magnet-driven tank arcade game.
They couldn't figure out how it was scored though, and watching the video I can't either. Shooting tanks seemed to have random effects and driving through one area inexplicably wrapped around the score counter.
How does aiming and scoring work in this game?
