Steve Ritchie details Sonic the Hedgehog pinball design, upper playfield innovation, and technical mechanics.
Sonic the Hedgehog is based on Sonic Generations IP specifically, chosen by Sega for style guide compliance
high confidence · Steve Ritchie states Sega 'chose Sonic Generations' and 'adds specifics' through style guides for artwork
The polycarbonate playfield uses AR (abrasion resistance) coating on both sides and can be buffed/polished like new
high confidence · Steve Ritchie explains polycarbon AR product specifications and maintenance, contrasts with past Stern manufacturing issue where sanding removed AR coating causing fogging
Upper playfield has nine possible shots total, with one featuring a wire form gate that can be removed for tournament play
high confidence · Steve Ritchie directly states 'there's a total of nine shots up there' and gate is added 'for now' but would be removed for tournaments
The custom stand-up targets on upper playfield use opto switches with beehive springs rather than micro switches
high confidence · Steve explains the linear target design uses 'a round shaft that passes through an aperture' with 'a little U-shaped opto thing' and PC board that is 'probably going to last forever'
The magnet loop mechanism requires no rear engines and operates one-way, with extensive code iteration and high-speed camera analysis by lead coder Bill Grupp
high confidence · Steve describes the magnet implementation and credits Bill Grupp with 'many, many iterations of code, of timing' to make it work
Sega rejected inclusion of the Sega logo/sound drop in the game 18 months ago despite Steve's desire to include it
high confidence · Steve states 'Everybody's asking for Sega... we asked them 18 months ago. Right. And they said, no. Can't put that in the game.'
Taylor Snyder is a young programmer who came to Jersey Jack without pinball experience but is a lifelong Sega/Sonic fan
high confidence · Steve describes Taylor as someone 'who came in here and didn't know pinball at all' but 'was a Sega aficionado' and 'a great programmer'
“Sega controlled a lot of things. They were very good about licensing now. I would say they're like one of the best licensors I've ever worked with. They're very cool. But they add specifics.”
Steve Ritchie @ early — Insight into Sega's approach to IP licensing and style guides, which directly influences design constraints
“I can't remember the first one I used, but what's cool about polycarbonate is the first thing, it can be buffed and polished and cleaned, and it's easy.”
Steve Ritchie @ mid — Addresses community misinformation about polycarbonate durability and maintenance
“I like games where I can walk up to it and I can't tell just by looking how to get the ball around all the different paths or what each shot does... I still don't even know every ball path of the upper play field.”
Don @ mid — Describes design philosophy around mystery and discovery in complex playfield layouts
“I wouldn't trust magnets. I don't know. A magnet can work if you've got metal on the sides, two ball guides, it's probably going to work fine.”
Don @ mid — Skepticism about magnet reliability in pinball design contrasts with Steve's implementation
“The worst thing with a magnet on the play field is if it's inconsistent, if it's supposed to throw the ball to target, And it works 90% of the time. That 10% is really disheartening.”
Steve Ritchie @ mid — Acknowledges the core reliability concern with magnet mechanics that makes the Sonic implementation noteworthy
“Bill Grupp, Bill Grupp is the lead coder. He had to work hard, man, to make that happen. Many, many iterations of code, of timing, lots of things we had to measure and look at with a high-speed camera.”
Steve Ritchie @ mid — Credits technical execution effort and precision engineering required for the magnet loop
“Everybody's asking for Sega. Like, we wouldn't ask. We asked them 18 months ago. Right. And they said, no. Can't put that in the game.”
Steve Ritchie — Reveals specific licensing negotiation details and timing of the request
design_innovation: Sonic uses a transparent polycarbonate upper playfield with edge lighting and AR coating, enabling ball visibility while simplifying wiring complexity. No inserts used on polycarbonate surface to preserve clarity.
high · Steve discusses polycarbonate AR coating durability, edge LED lighting from underneath, intentional design to keep ball visible, contrasts with inserts approach
design_innovation: Custom stand-up targets on upper playfield use opto switches with beehive springs instead of traditional micro switches, providing adjustable PC board design intended for long-term reliability
high · Steve describes linear target design: 'round shaft that passes through an aperture' with 'U-shaped opto thing' on PC board that is 'probably going to last forever'
design_innovation: One-way magnet-driven loop mechanism triggered by opto sensor as ball enters, operates at any speed from slow pushes to full shots, required extensive code iteration and high-speed camera analysis to achieve consistency
high · Steve credits Bill Grupp with 'many, many iterations of code, of timing' using high-speed camera measurements; describes one-way operation and speed-independent triggering
design_innovation: Fourth magnet positioned below six badnik targets adds unpredictability—sometimes throws ball back up the middle hole, sometimes allows drain, adds excitement while providing ball saves
high · Steve describes magnet placement and behavior: 'interferes with a lot of stuff... does interesting things... saves a lot of balls... from going down the middle'

Steve initially resisted doing a 'cute' themed game but was won over by the fast gameplay and Sonic theme
high confidence · Steve says 'I did not want to do it in the beginning I never made a game with little flowers... they don't do cute' but changes stance: 'You do fast... I do fast'
“I did not want to do it in the beginning I never made a game with little flowers... but it's compelling... the more I saw the game, the more I thought, wow, it's fast.”
Steve Ritchie @ mid — Shows design evolution and how game speed eventually won over initial aesthetic reservations
“The plunge goes into the orbit. And then I was able to combo right into some ramps when I was hitting right. So, yeah, the flow is here.”
Don @ late — Confirms quality of shot flow and combo design during hands-on play
“Every time I was draining out, I was a little bit sad. And that's kind of what you want if you're doing an upper play field or a lower play field area.”
Don @ late — Describes the emotional engagement with the upper playfield design—wanting to stay in play rather than drain
licensing_signal: Sega required use of Sonic Generations IP specifically with strict style guide compliance. Rejected Sega logo and associated sound drop 18 months into development despite Steve's desire to include them.
high · Steve states: 'Sega wanted us to use it... they add specifics... if it's not in the style guide, it doesn't matter... they're not going to sign off' and 'we asked them 18 months ago... they said, no'
design_philosophy: Steve prioritizes playfield designs where players cannot immediately understand all shot paths and mechanics—complexity that rewards exploration and repeated play
high · Steve says 'I still don't even know every ball path of the upper play field because sometimes I'm shooting back there... the ball is popping up different places' and values this mystery
design_philosophy: Steve emphasizes keeping the ball visible to players as much as possible on playfield, which drove the polycarbonate upper playfield choice and rejection of inserts
high · Steve explicitly states: 'I think it's really important to keep the ball visible to the player as much as I can' and 'I'm not putting any inserts in a polycarbonate field. It's clear, dudes'
product_concern: Previous Stern manufacturing issue: polycarbonate windows in lower flipper area were sanded, removing the AR coating, causing fogging in some games still in arcades. Steve acknowledges this as source of industry rumors about polycarbonate durability.
high · Steve discusses: 'We did have a problem once at Stern... they sanded the whole thing... they took off the AR coating... it kind of became foggy... some are still out there that were foggy'
personnel_signal: Sonic development involved Taylor Snyder (young programmer, non-pinball background but Sega/Sonic fan), Bill Grupp (lead coder), Joe Katz (mentor), and Steve Ritchie (designer)
high · Steve describes Taylor as bringing programming skills and Sonic fandom, credits Bill Grupp as lead coder with Joe Katz as mentor figure
gameplay_signal: Upper playfield is designed to keep players engaged with quick exit options if desired, but compelling enough that players want to stay—multiple shot paths, center bumper for rescue, flipper feeds from lower playfield
high · Don describes: 'Every time I was draining out, I was a little bit sad' indicating emotional investment; Steve describes exit paths: 'you can exit pretty quickly' but 'it is fun'
design_innovation: Spin Dash mode freezes ball on ramp, player builds cursor position using flipper pounding, selects green area for collection bonus. Similar timing-based interaction to pyrotechnic moment in Guns N' Roses but active player-controlled rather than passive
high · Don describes: 'ball freezes on the ramp. You pound the flippers. The information's on the screen... you move this little cursor until it's over a green area'
gameplay_signal: Don reports shots feel consistent and responsive to player input after second/third game, finding shot positions on flippers reliably when maintaining consistent reflexes
medium · Don states: 'In my second or third game... I was already finding where the shots were on the flippers. They were fairly consistent as long as I was consistent with my reflexes'
