Playing Pharaoh the other night, the ball got stuck in the lower right kick out and wouldn't fire it out on it's own.
I shut the pin off, powered it on and that kickout works now.
I noticed when I start a new game and if I keep adding players till I get 4 players, every time I press START again I get 12,000 points added to the current players score (Player One since I haven't even started the first ball).
I also took out the balls, lifted the playfield and started a game that way.
I notice that same lower right kickout fires every time I press START with no credits on the game if this clue helps.
