never played it but I think it works similar to pinball where you have to shoot various targets and shots to light certain things and gain points based on those shots

Its kind of like space invaders, These aliens light up and move down the playfield, and you have to shoot them/the target behind them as they are moving. It also has certain targets to hit, that light up to get these nuke things that kill everything.

Its a wierd williams sudo pinball game, I played one at an auction in Toronto it sold for $300 in really nice shape. I should have bid on it cuz the guy sold it a month later on kijiji for $1100.

Yeah, i think you are refering to a machine called Take Five.
Was this the one? Go tou youtube and type in take five pinball, a guy has restored one and is playing it.
There used to be one in the early eighties at a local squash centre, not many left for sale.

I have a line on a 200$ project hyperball I just have not gotten around to pick it up. They are supposedly a real pain in the ass to get working and maintain.

Here's a rulesheet:

Definitely a funky game, but sort of fun.

I probably wouldn't bother maldoror. They are a pain in the butt to get working. Your better off trying to find an early 90's light gun game for that much scratch (Hyperball is very much a shooting game), and involves less repair....like a Terminator 2 light gun game that goes for little less than $200 bucks.
