Quickie Version:

UTAD. Only shoot at the roto-target when the number you hit matches the one lit amongst the dominoes on the playfield below it or when it shows a star.

Go-to Flipper:

Balanced

Risk Index:

Very High; critical to get ball into upper portion of playfield; watch out for side drains when the ball exits the bumpers in too straight a line towards them! Highly angled exits are safer.

Full Rules:

Full version of this isn’t much more. The two sets of three standup targets aren’t worth the risk since shots at them usually rebound into the central block and then back down randomly. The roto-targets and the standup between them are likewise risky for rebounds and should be avoided most of the time. When the domino face in the roto-target window matches the number of dots on the lit domino below, scoring the window target is worth 500 points. If the window shows a star rather than a number, that’s always worth 500. Other than that, just go up top all day and try to nudge the ball into either of the 500-point saucers. The lit domino is advanced counterclockwise through the snaking line below by the two side standups that are currently lit, the two top lanes that are currently lit, and the two saucers.
