'the number . . . . has to be equal or more the number . . . .'
Yes, I agree.
From the images in #1
what isn't shown is whether the individual lane tables were with the lightboard shown, or were they being built from scratch.
I was thinking easy such as an 8 input encoder multiplexer. See p7 on combining to make 16 or 32
complete 74HCxx series
then use another as a 'bank' selector and do the decoding in a software table. Maybe this is the same/similar to the port expander you mentioned.
'it will also be a challenge . . . have to . . . in order to not let always the same win'
Ahhhh, but that was the lure of the carnie experience, to attempt to queue up to get the better lane. I remember five lane tables on the game I saw years ago. @matencio mentions two in this thread and three in the original post.
I also agree with you, that if the tilt of each table is not easily adjustable to allow the ball to fall through the gates at the same rate, a small usec delay could be added in software.

@Robin, so my conclusion about the number of (simplified) pinball machines is it has to be equal or more the number of simultaneously playing players. That's quite some work to get done... and it will also be a challenge to make all machines behave the same way in order to not let always the same one win (even though also such inconvenience could be taken care of by the software).
