Sonic pinball stream with JJP engineer Bill Grupp discussing design, mechanics, and 48fps tech.
Bill Grupp was the lead software engineer/programmer on Elton John at JJP
high confidence · Joel: 'if you've enjoyed Elton John in the past, that was all Bill and team'
Sonic is only Steve Ritchie second game at Jersey Jack Pinball
high confidence · Bill Grupp: 'And this is only his second game at JJP.'
The topper features servos, steppers, and a high-res display; design by Steve Richie, engineering by Dan Lee
high confidence · Bill: 'That that was all Steve... Dan Lee is the one who actually figured out how to make it all work.'
Sonic is the first JJP game running the screen at 48 frames per second (double normal frame rate)
high confidence · Bill: 'this is the first game at JJP where we're running the screen at 48 frames a second... that came out of seeing the high resolution footage'
Video content in Sonic's backglass is a combination of recorded gameplay and material provided by Sega in 4K or higher resolution
high confidence · Bill: 'It is a combination of stuff we recorded and and stuff that was provided by Sega. Nice. Um so it is all super high resolution 4K or better.'
Chemical Plant track in Sonic has one less checkpoint than Green Hill, making it technically easier
high confidence · Bill: 'Chemical Plant is actually slightly easier. It has one less checkpoint.'
Bill Grupp designed the feature allowing players to select starting track to avoid forced repetition of Green Hill
high confidence · Bill: 'that was mine [the track selection feature]. I partly because... I was adamant that we had to have a way to change the level.'
More content for Metal Sonic and Shadow characters is planned for future code updates
high confidence · Bill: 'Metal Sonic and uh Shadow. Um yes, definitely more coming. Shadow is already in the chaos control feature.'
“Every time you hit the target, the left target, you spawn a new chow egg. And light the advanced chow insert on the orbits.”
Bill Grupp @ mid-stream during rule explanation — Explains Chao Garden side rule mechanic and how it interconnects with main playfield orbits
“if you can trap the ball up there forever, um your ball times just go crazy and you kind of take some of the fun out of the game. But if you just make one shot and roll off, what's the point of having an upper play field?”
Bill Grupp @ during upper playfield design discussion — Core design tension in upper playfield balance — time spent vs. engagement
“24 frames at the speed that Sonic runs, that was definitely not fast enough... the video you're watching now of Sonic running, that's all running at 48 frames a second. That's so closer to video game resolution.”
Bill Grupp @ technical discussion section — Technical innovation justification for doubling screen frame rate to match game speed expectations
“Steve has his style... he's been making games longer than almost longer than I've been alive, but not quite.”
Bill Grupp @ game design philosophy discussion — Acknowledges Steve Richie as design influence and elder figure in the industry
“I don't want to do something that you know I just copied from another game. I want to do something that really works in the Sonic world and takes advantage of all the lights we have in this game.”
Bill Grupp @ lighting design discussion — Design philosophy: theme-appropriate customization vs. reuse
design_innovation: Sonic is first JJP game utilizing 48 fps screen display (double normal 24 fps), specifically implemented to match high-speed Sonic video game visuals and compensate for scaling down 4K+ source material
high · Bill Grupp: 'this is the first game at JJP where we're running the screen at 48 frames a second... 24 frames at the speed that Sonic runs, that was definitely not fast enough'
design_innovation: Sonic features innovative animated topper with moving servos, stepper motors, and high-res display; technically complex and heavy; designed by Steve Richie with engineering execution by Dan Lechek
high · Bill: 'there's servos and steppers and the, you know, the giant high res high-res display. It's there's a lot of cramped stuff crammed into that topper'
gameplay_signal: Sonic features multiple rule systems: track selection (Green Hill, Chemical Plant), ring combos leading to 100-ring extra ball, Chao Garden side quest with target-spawn mechanic, Sonic Heroes multiball with team selection affecting jackpot placement
high · Bill explains: Chao spawns eggs via target, rings accumulate via combo shots, Sonic Heroes teams (Sonic, Chaotics, Dark, Rose) determine multiball jackpot locations
gameplay_signal: Upper playfield is central focus; careful balance between time-on-playfield and ball retention; center post aids navigation despite massive flipper gap; center post shot combination (cradling/bouncing over) is core mechanic
high · Joel: 'the upper playfield's like my favorite part of the game' and Bill discusses tension between trapping ball too long vs. not having meaningful upper play

Rings carry over ball-to-ball and are not reset between balls
high confidence · Bill: 'they carry over ball to ball. You still collect um the number of rings you have in bonus at the end of the ball, but they don't reset.'
design_philosophy: Steve Richie's design approach influenced game speed and style; Sonic's fast gameplay is deliberate match of designer expertise (known for fast layouts) to IP (fast video game character)
high · Bill: 'Steve has his style... he's been making games longer than almost longer than I've been alive... Steve likes making fast games. Sonic is a fast game. So yeah, it is.'
product_strategy: Track selection feature (Green Hill, Chemical Plant) implemented to reduce player fatigue from forced repetition; Chemical Plant technically easier (one fewer checkpoint) but Green Hill chosen as default start due to iconic status
high · Bill: 'I was adamant that we had to have a way to change the level... everybody knows Green Hill and if it wasn't the first thing you saw when you started the game, we would have heard about it forever'
licensing_signal: Sega provided 4K+ resolution video content for Sonic backglass; Sonic video game footage integrated into playfield progression visualization
high · Bill: 'It is a combination of stuff we recorded and and stuff that was provided by Sega... all super high resolution 4K or better... plays parts of the level depending on your checkpoint progress'
code_update: Upcoming code updates include: emerald power system (blue=Chao, yellow=rings, red=Batnic attack, white=Tails, purple=Froggy); expanded Shadow and Metal Sonic character content; speed component for right ramp scoring mechanic
high · Bill: 'in an upcoming version... having an emerald, a specific emerald... will make the chao shot worth more' and 'definitely more coming' for Shadow/Metal Sonic and 'I probably will add something that adds a speed component'
community_signal: Community comparison: players likening Sonic to Black Knight Sword of Rage 4 in terms of speed/intensity; debate about whether game feels too fast or appropriately controlled; positive reception of lighting restraint (selective illumination vs. constant displays)
medium · Joel: 'people are like, this feels like Black Knight Sword of Rage 4... like that's kind of like, you know, and it's like Okay, I can respect that. But it I mean, it is fast, but I don't think it's uncontrollable'
content_signal: Flip n Out Pinball live stream of Sonic with manufacturer engineer; giveaways (t-shirts, beef sticks, signed materials); high community engagement in chat with rule questions and gameplay discussion
high · Stream hosted with Bill Grupp present; multiple giveaway drawings; audience participation in chat with winner announcements
market_signal: Multiple recent JJP releases creating buyer decision tension: players choosing between Transformers LE, Sonic, and Harry Potter; multiple viable options in premium manufacturer segment
medium · Joel: 'immediately people are just like which one should I get? Should I go Transformers LE or Sonic? Should I go Harry Potter or Sonic?... there's so many good games out right now. There's no there's no right or wrong answer'
personnel_signal: Bill Grupp confirmed as lead software engineer on Sonic and Elton John; suggests established technical role at JJP; appears in public-facing promotional streams
high · Bill introduced as 'lead software designer/lead programmer' and credited for Elton John software design; actively discussing technical decisions in live stream
