My first pin was a Bally Hang Glider. It still holds my interest because of the "earning" double bonus feature.

There is a light on the right orbit that sequencially goes on and off to earn double bonus for that ball. It can be set to be active based on 10 point switche hits from 2/10 to 5/10.

There is no automatic double bonus on third and/or fifth ball. Hitting that orbit shot when the "lights double bonus light" is on is the only way to earn double bonus.

Playing other games that automatically give you double bonus doesnt feel as satisfying cashing in on a big bonus.

What other games have a similar double bonus feature ? Anything more interesting the just getting "A,B,C" rollovers ?
