I created a Pinball Game (a Web Application, not a machine) for this same purpose. It's called "Party Pinball" and is in the test phase currently, but works great. Game Rules can be found here: https://pinballzoo.com/Games/GameTips?id=967
You will need to register on the site to be able to see/play Party Pinball.
The Party Pinball App tracks your pinball scores and points, while adding a few new rules....
- The Timer - limited ball times
- Party Rules - custom rules per game
- Coins - buy time, and collect to win!
3 Coin Types
- Blue - used to buy time, each player starts with 5 Blue Coins
- Gold - earn 1 Gold Coin per victory - collect to Win!
- Purple - collect for prizes (optional)
For first-time users, it works best to have 1 person be the "Ref" who will interact with the App (not a player).
After people are comfortable with the app, you can have players Ref for each other.
