Portal Pinball is a physical pinball game developed by Multimorphic, Inc. for the P³ Pinball Platform. Released in 2024 as an official collaboration with Valve, the game utilizes modular hardware to combine a 1080p dynamic floor display with a physical playfield.
The machine is notable for its application of Aperture Science-themed hardware, including 10 RGB-illuminated physical portals and a unique "Momentum Jump" ramp system that replicates the kinetic properties of the Enrichment Center.
Features
The game is structured around the P³ platform's modularity, utilizing a swappable upper module and an optional extension kit.
Technology and "Portal" Mechanics
The defining feature of the machine is its ability to simulate instantaneous travel. While traditional pinball machines are limited by the travel time of a single ball, the P³ platform utilizes a 16-ball storage system located directly beneath the upper playfield.
When a ball enters a physical portal, the game "captures" that ball and simultaneously launches a new ball from a hidden trough at the corresponding exit portal. This allows for:
Momentum Conservation: The game tracks the entry speed of the ball and uses high-speed solenoids to launch the exit ball at a matching velocity.
Simultaneous Portals: The large ball count allows for multiple objects to be in flight through different portal pairs during complex multiball modes.
Upper Playfield Module
The Upper Playfield Module is the mechanical core of the game. It includes:
The LOFT (Library of Failed Tests): A specific upper-right sub-section of the module where balls are sent via portal. It houses the Companion Cube Ball Lock, which physically archives balls on a metal grating for multiball initialization.
Angled Panel Portal: A specialized ramp requiring the player to build enough momentum to clear a physical gap into one of three landing zones: the pit, the lower landing zone, or the upper grating.
Aerial Faith Plate: A high-powered solenoid diverter that launches the ball across the playfield.
Sentry Turret: A motorized, rotating sculpt with synchronized lighting that "fires" digital bullets at the ball as it passes.
Reggie Toy: An animated sculpt of a new personality core who reacts to gameplay events.
Portal Extended Features
The Portal Extended edition adds the "Portal module extension," which floats over the lower LCD screen to bring the action closer to the flippers:
Hard Light Bridge: An elevated cross-playfield bridge facilitating ball transfers between the left and right flipper returns.
Fourth Flipper: A dedicated side-target flipper on the left side of the playfield.
Dynamic "Glass Ramp": A transparent ramp that can be raised or lowered based on gameplay state.
Gel Tube Kickback: A hidden physical mechanism in the outlane.
Gameplay
Gameplay begins in "the Hub" (based on the Cooperative Testing Initiative location), where players navigate toward seven unique Test Chambers:
The Big Fling
Encouragement via Discouragement
Proactive Energy Redirection
It Takes Two
Shortcuts
Gels
Rat Man's Den
The ultimate goal is to complete all Chambers to unlock the final Wizard Mode: a face-to-face battle with GLaDOS.
Characters
The machine features original voice work and appearances from:
GLaDOS: Voiced by Ellen McLain, she provides context-specific taunts and serves as the final challenge.
Reggie: A "Teambuilding" personality core created specifically for the game, voiced by Marc Silk. Reggie acts as a guide through the Hub and Test Chambers.
