This sounds incredible.
Good luck with this seemingly insane project. But oh wow this would be excellent.

Have you assembled a prototype playfield with switches & interface?

I love this project, but you know that. I wonder, when it's all done, how compact one of these could be made?
Like, how many different playfields would you need to play a majority of the games? 3?
I imagine making the cabinet, with the glass and ball mechs and playfield, and just having an output for the monitor at the back really reduce the profile to the essentials.

In your examination of the portioning mechanisms, have you found any features that might have been secretly lucrative for a player? Like some double-or-nothing circuits that actually gave > 50% odds?

Only 3 games have rollovers?
I would definitely hunt for a 25 hole rollover playfield though. I love having rollovers light as a gameplay option. Played a lot of Surf-Club and Sea Island recently.

In a game like Surf-Club, what's it called when you add a credit and the game randomly gives you a feature, a teaser, or just flashes and does nothing?
I always assumed that was done somewhat unfairly to make things harder to get.

One day I'd love to see a diagram that explains the math beyond the mixers and features and stuff. Maybe write a book when done this project.

No way, for me I'd need the aesthetic of the traditionally sized pinballs, fresh rubbers, and normal plunger mechanism.
I would just want the option to reduce rest of the space required as I have space issues here and would want to be able to store the machine easily.

Another Q about "increase in your odds or awards towards a feature".
Are you talking about the "teaser" lights that go on, but you're not yet awarded a feature?
I always wondered if those teaser lights coming on actually meant your odds towards that feature were increasing, or if they were just there to dazzle and distract the player.

If I put a coin in and nothing ends up happening after the coin flash, are there internal feature odds that also might still be potentially increasing, even if nothing turns on with that credit?

OK, then I definitely will go with one of those. I really enjoy the hold even/odd features.
Beneath the playfield, how much room does that hardware occupy? i.e. wondering what the minimum height of a custom bingo cab with a Surf-Club playfield and normal playfield glass on top would have to be.
I imagine the Length and Width would just be a a few inches beyond that of the actual playfield.

thanks for taking my questions!
Can a feature step all of the way right away? Or multiple times at once? And if so curious as to how rare of an occurrence the multiple steps would be.

I don't understand what a time tree is, what games use it?

Congrats on Gay Time, that game looks fun. The "Magic Pockets" feature seems like a very unique mechanic. Will there be an allowance for generic playfields to digitally emulate Magic Pockets movement?

In terms of unique physical playfield elements, it would be interesting to do up a venn diagram showing the options of how some features overlay between games. Lit rollovers, odd/even holds, magic pockets, any other mechanisms unique to certain playfields?

I was going to ask about the Magic Lines feature, but this photo demonstrates it quite well!

HUZZAH!!!!!

NNNOOOOOOOOOOOOO

sending some Ottawa peeps to come find you in Allentown and try it!

I would definitely pay for one of these ready to go. I would want the main unit, no legs needed, an external output for a screen to plug in. It would be able to travel so well. Even if I just had one type of playfield and stuck to those series of games.

Do you keep a metric of "credits added"? I'm the lady at the bingo machine dropping in 20-40 nickels trying to get a huge array of features lit up.

I too am in. Would even consider paying someone to make me one if it was done up as a kit.
I've mentioned it to Nick before, but I just want the bottom bingo chasis and a monitor output on it. Could slide it out of storage, plug it in to a monitor, and away we go.

I would have zero problem with $1/credit, provided I trusted that you would be honouring my 5-line payout!

that looks amazing

rah rah rah rah!

be sure to add this machine to your "wish list" if you would like to own one some day.

woah, that's a pretty darn cool game! That center Star hole looks wicked difficult. https://www.ipdb.org/showpic.pl?id=864&picno=16903&zoom=1
The hole distribution is really sinister/clever. The plungeable shots at the top like #1 only appears on a single card. 11 on 2. #2 only appears on 2.
