Thanks to Aurich's great idea on this thread:
... there was a very inspiring post...
Quoted from TheFamilyArcade:
I like the idea Aurich. But even more simple, why not keep the current mechanism, or something very similar, and just make it less active?
Instead of “spinners” that will ultimately wear out, treat the 3 moving, concentric circles as a combination lock. That way you still have the feature of different insert alignments giving rewards. The circles still move, but only sometimes, and slowly, not violently spinning.
Better yet, make their movements correspond to player shots on the playfield. Each circle moves in a specified direction and number of places based on what the ball hits, putting the player in control of the rewards he receives from the “combination”. The player would have to initiate a sequence to activate the rings, and once the rings are aligned properly, the player hits something to cash in the reward.
The rings will reset back to where they were before, for each players turn, so one player doesn’t disrupt the progress of another.
This takes away the magnet aspect though.
I think this is a fantastic idea. Making it more a part of the gameplay perhaps even improves the coolness of this hardware! And issues with being too loud - gone. Issues with reliability - gone. Pissed off buyers - probably gone. Need some more ball action then put in some magnets. Even improves upon the fact that you couldn't see the disc when it was spinning fast - can look cool all the time. Another advantage - can ship game now and code for this can catch up later.
