Domino and PlayMates, both released by D. Gottlieb & Co. in 1968, are electro-mechanical pinball machines designed by Ed Krynski with artwork by Art Stenholm. Domino is the replay version, while PlayMates is the add-a-ball variant.
PlayMates
Quickie Version:
UTAD.
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:
While this uses the same playfield as Domino, the scoring is different enough that I list it separately. This was the add-a-ball version, Domino was the free game version. On PlayMates, you never want to hit the roto-target! It’s only worth 50 points regardless of what numbers show in the windows. The saucer values are now only 200, so the side stand-up 1 through 6 numbered targets now come into play since a lit one at 200 is worth the same as a saucer. You still should treat this as a UTAD game, but hitting a lit side target is fine if the rebound from that particular target tends to be safe.
