The "Aztec" pinball machine, released by Williams in 1976, is an electro-mechanical game designed by Gordon Horlick with artwork by Christian Marche.
Quickie Version:
UTAD - - It’s all about the spinner from the right flipper and the U-chute on the upper right from the left flipper.
Go-to Flipper:
Right
Risk Index:
High; spinner safest, U-chute next best but watch where the kickout from it goes
Shots to Master:
left spinner and right U-chute, which can also be a grazing bank shot off the outside of the chute.
Skillshot(s):
The center lane at the top, which lights the spinner for 1000. If you miss it, try to get the center lane whenever you send the ball to the top through the spinner. Once the spinner is lit, try to get the lit side lane of the three at the top - - either the right or left lane will always be lit for advance bonus, they alternate on switch hits. Also, try to have the ball go over the top center rollover disk to advance bonus as it’s bouncing back and forth between flaps and rubbers at the top.
Full Rules:
After you’ve UTAD-ed enough to get your bonus up to the maximum base of 100,000, shoot for either the Z or T standup target to light the spinner lane and U-chute for Double Bonus. If Extra Balls are on, once you have both max bonus and double bonus, you can consider going for the remaining AZTEC letters. Completing A-T-Z or A-C-E lights the center standup for Extra Ball. Since T and Z both light double bonus opportunities, they’re the more useful ones to pair with the A lane. Never shoot the C or E unless extra balls are on and you just need one of them to light the target. Even then, I might shoot both T and Z rather than just one of C or E. Key feed: the kickout from the U-chute. Depending on the strength of the kicker and the reaction of the upper right bumper, you may be able to nudge the machine so that the ball rebounds off of that bumper back into the u-chute. Done several times in a row with multiple letters lit, this can add up to a lot of easy points quickly. On many Aztecs, though, the kickout may glance off the top right bumper, then skid off the rubber on the outside of the chute and drain down the middle.
