The Internet Pinball Serial Number Database or IPSND collects serial numbers of pinball machines and publishes a database of these on the Internet. Our goal is to make available a registration of all pinball machines in existence and allow tools for slicing, dicing and visualization of the data.

Games: 6,555  Serials: 61,760  Visitors: 59,600,824  Members: 5,042  Photos: 37,586  Lat/Lng: 31,830  Masks: 61,760(942.18%)  Traits: 557  Nudges: 190,919  Backglasses: 1,865
  Most Serials: Twilight Zone(1,213)  Most Submissions: Dennis Braun(5,706)  Most Points: Dennis Braun(42,427)  Highest Quality: EM-fan(9.45)  Most Nudges: King of Pinball(25,019)
Did you know??? You may now submit Lattitude/Longitude data for the location of the game that has the serial number. This allows us to show the travels of a game over time as it is bought and sold.

IPSND is now a 501(c)3 Non-profit!
Hey everyone...  It took about 6 months of paperwork and fees but the IPSND (part of the ISND - Internet Serial Numbers Database) is now officially classified as a US Non-Profit. There were a couple of reasons that I took this direction...
  1. Hosting costs are greatly reduced for Non-Profits
  2. Donations are US Tax Deductible (not sure how that might work in other countries?)
  3. This keeps the IPSND money separate from my own money
  4. Ideally this makes things easier to transition to a new owner in the next 20 years.
More to come on this topic as the year goes on. Thanks to all that have supported the site in the last 16 years!

New Database Server too
Just brought a new SQL Database Server online tonight... had about a 30 minute downtime, apologies! Should be solid now and I will be mucking around a little more but I will try not to break anything.

New Web Server
Got a little upgrade today to a new web server with twice as much memory and twice as many CPUs. Hope that the site runs a little zippier now. I will be monitoring the performance and will see if I need to do anything to continue to tweak the VM. Next step will be migrating the database which will most likely happen the weekend of March 26th.

A couple noteworthy items...
I did some data cleansing over the past week and found that over the years there were a good amount of foreign games that had come across from the Internet Pinball Database with mangled names due to the way I was decoding the Unicode in their names. I ran a fix on this so games like Apollo Moon (アポロムーン)will now have the appropriate characters (Japanese in this example).

Also, I ran across the fact that there were no serial masks defined for Jersey Jack Guns &  Roses games (Guns N' Roses Not In This Lifetime (Standard Edition), Guns N' Roses Not In This Lifetime (Limited Edition)and Guns N' Roses Not In This Lifetime (Collector's Edition)) so I got those assigned. Kudos to Jersey Jack for giving each game a different serial number prefix so you can tell the specific model by the serial number. That is some smart decision making in my book!

Happy New Year 2022!
Wanted to put a quick update here for everyone.. thanks to all who have been continuing to participate in the database through 2021 which has been an understandably difficult year for everyone.

This past year certainly has accumulated a good amount of bugs/issues with the site. Some of which I have been able to fix and some are requiring a more in depth change and are still outstanding. When I originally wrote this site 16 years ago, it was fresh and popping and admittedly, it needs some serious rebuilding in many ways. I'm in the process of evaluating how big of an overhaul I want to take on with the site in 2022 and I will be reporting more here in the coming months. For right now, I'm going to solve some of the more problematic issues (flaky emailing is #1 right now, fixing stats is #2 and forcing SSL/HTTPS is #3). 

Additionally, I have been hosting this site on a Microsoft Azure VM for the last few years. It runs about $150/month so I will be evaluating a move to a different host. 

Another fun update is that I think I have all my ducks in a row to make IPSND a 501(c)3 Non-Profit organization. Upsides are that donations will be tax deductible in 2022, more info coming soon on this.

Best vibes to everyone and here is to an improved 2022 for all!   Jess
