i'm working on a wiliams wing ding, schematic is on its way. i do have some questions though, never really saw a game like this. first, am i correct in assuming you load 5 balls, or being an addaball, does it take more? it has a long ball trough with a bunch of roll over switches, like a gottlieb, but it also has a ball count stepper unit. thats what has me thrown, that it has both. if i load 5 balls, when i start a game it resets, but there is no scoring, no switches score. if i only load 1 ball, it will start a game and play , but when the ball drains, it goes game over. the ball count stepper is clean and free. the second switch in the trough that the ball hits when it drains is the one that causes game over. how do the trough switches work, in conjuction with the ball count unit ?

thanks

i know what an add a ball is, but that doesnt answer any questions. why so many ball trough switches ( that usually count balls used) in a game with a ball count stepper that counts balls up and down?
