The Engineering Truth Behind Interblock’s Hybrid Gaming System

โก The Quick Answer: Is Bubble Craps Rigged?
NO – Bubble Craps is NOT rigged. The machines use real physical dice in a transparent dome with compressed air, regulated by gaming commissions, and certified by independent labs. The house edge comes from mathematical probability, not manipulation.
๐ฒ What Exactly IS Bubble Craps?
Bubble Craps is a hybrid electronic-table game developed by Interblock Gaming, combining mechanical dice rolls with fully automated betting terminals. Unlike virtual RNG craps, this system uses actual physical dice inside a sealed, transparent dome. The roll is triggered by a timed pulse of compressed airโremoving human involvement entirely.

Interblock’s transparent dome system with multiple player terminals
Key differences vs. electronic craps:
- Polymer resin dice, same size/weight as live casino dice
- Transparent dome = public verification of outcomes
- Single physical result broadcasted to all terminals
- No RNG, no virtual dice, no dealer
๐ง The Engineering Truth
The Patents That Reveal Everything
Each Interblock system is patented with highly detailed descriptions showing no outcome manipulation capability, instead emphasizing redundancy, transparency, and physical validation. These are U.S. patents filed through the USPTO, reviewed and approved after examination of the dice mechanics.
๐น US Patent 11,195,370 โ “Craps Gaming System”
Section [0011]: Describes use of real dice inside a transparent dome, pneumatically launched via compressed air.
Section [0045]: Confirms the dice outcomes are captured via sensor analysis post-roll, not influenced by player input.
Section [0053]: Emphasizes use of camera and motion detection to log randomness of dice movement.

๐น US Patent 11,325,025 โ “Methods for Controlling Movement of Dice”
Section [0003]: Explains that the machine’s purpose is to offer fair, repeatable, and randomized outcomes.
Section [0030]: Notes air pulses are pre-programmed and not responsive to player behavior or wagers.
Section [0048]: Discusses sensor calibration, not manipulation โ designed for detecting invalid rolls (e.g., cocked dice), not changing them.

๐น US Patent 10,846,496 โ “RFID-Based Dice Reading System”
Section [0022]: Describes use of RFID chips only for dice position reading, not to influence or alter results.
Section [0040]: Focuses on accuracy of result detection โ not outcome generation.
Section [0058]: Confirms redundancy through both optical and electronic reading to avoid manipulation or error.

Patent US10,846,496 – RFID dice reading technology
The bottom line: The patents are not about controlling results. They’re about ensuring the dice roll is random and visible. Manipulating outcomes would violate design purpose and testing certification.
๐๏ธ Regulatory Oversight: Why Rigging Is Impossible
Before any game hits a casino floor, it must pass certification from independent labs and government regulators. Bubble Craps machines undergo rigorous approval processes in multiple jurisdictions.

Certified by independent labs and gaming regulators
Independent Testing Labs:
- Gaming Labs International (GLI) โ Tests air pulse timing, result randomness, and tamper protection.
- BMM Testlabs โ Audits sensor accuracy and firmware compliance for regulatory approval.
State Gaming Commissions:
- Nevada Gaming Control Board (NGCB): Requires all machines undergo GLI certification and device approval.
- Other approvals: NYSGC, MGC, PA Gaming Control Board, etc.
Tampering with game outcomes = license revocation, massive fines, and criminal penalties. No casino would jeopardize their multi-million-dollar operation over a single dice roll.
๐งจ Debunking the Conspiracy Theories
MYTH: The machine knows your bet
REALITY: Patents like US11,325,025 confirm the air puff that launches the dice is triggered independently of wagers and user interaction.
MYTH: Dice are magnetic
REALITY: The dice are made of standard, non-magnetic polymer resin (see Interblock tech sheets). No ferromagnetic components or fields are involved.
MYTH: Your seat affects the outcome
REALITY: One set of dice rolls per round. Results are broadcast simultaneously to all terminals via one video feed. Seating has zero influence.

Casinos already win in the long term through mathematics. The expected profit is baked into the game structureโno trickery needed. That’s why Nevada mandates public posting of odds and randomization mechanics under NRS 463.15997.
Rigging would add risk, not reward. It’s unnecessary, illegal, and inefficient when the built-in math already does the job.
