Your rails are improperly placed. Aztec is a drain monster and certainly not a fun game for a 9 year old to play. I have come to accept that many people love Aztec because it IS such a hard game to play. My Aztec is almost a perfect 10 from backglass to playfield after I restored it. I will never sell it and play it mostly because of it’s difficulty, but I truly hate the machine and would never recommend someone buys one in a small collection.
