Quoted from etolisano:Game resets all 4 players to zero upon pushing start just one time;
When ball drains, it jumps to second player then upon drain it goes to third player.
After drain on third player, it goes back to first player and plays through all 5 balls.
The Ball Count Unit should advance each time the last player drains. When that happens is determined by the Coin Unit and Player Unit in the red box. The Coin Unit keeps track of how many players there are and the Player Unit keeps track of which player is currently playing. When the Ball Count Unit advances it fires the Player Reset relay which resets the Player Unit back to player 1.

It sounds like you may have a poor connection through your Coin Unit since the first ball plays through several players but other balls stick with player 1. It could also be that the Coin Unit doesn't reset properly at the beginning of the game.
