Solution Overview

Problem

Traditional wagering systems in card games, such as baccarat and Chinese poker, often involve the house bearing the risk of patrons winning, which can lead to inefficiencies and lack of player engagement due to the absence of skill-based elements.

Innovation Solution

A system that allows players to wager against each other, with hidden initial card sets and optional additional cards, incorporating skill through mathematics and bluffing, and a house that takes a percentage of the winnings as a rake.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the house bears the risk of patrons winning in traditional wagering systems, then the game structure remains simple and straightforward, but player engagement decreases and skill-based elements are absent

Engineering Contradiction:
Improveskill-based elementsVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the traditional house-vs-player wagering into player-vs-player matchups. By dividing the game into individual player pairs where one player acts as banker and another as challenger, the system introduces skill-based strategy while maintaining a manageable game structure. Each segmented matchup is independent and resolved through clear betting rounds and card dealing sequences.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a computer system as an intermediary that manages the complex game mechanics, card dealing, betting calculations, and outcome determination. This intermediary handles the computational complexity of tracking multiple player accounts, calculating rakes, managing betting rounds, and determining winners, thereby enabling skill-based gameplay without overwhelming structural complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If the house takes a percentage of winnings as rake, then profitability is maintained for the operator, but player winnings are reduced

Engineering Contradiction:
Improveoperator profitabilityVSAvoidplayer winnings
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The patent extracts the rake (operator profit) as a separate, distinct component from the player winnings. By taking out a predetermined percentage or fixed amount from each pot as rake before distributing winnings to players, the system clearly separates operator profitability from player rewards. This extraction occurs automatically through the computer system, ensuring consistent profit for the operator while maintaining transparent player payouts.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If players wager against each other instead of the house, then risk shifts from the house to patrons, but the game requires more complex betting and card management systems

Engineering Contradiction:
Improverisk distributionVSAvoidbetting and card management system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where players directly manage their own betting decisions, card selections, and wagering strategies. Each player independently controls their bankroll, decides when to challenge or accept challenges, and manages their own betting rounds. This self-service approach distributes risk among players while the computer system automatically handles the complex management tasks of tracking bets, dealing cards, and resolving outcomes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical card dealing and betting management with an automated computer system. The computer handles card shuffling, dealing, tracking player hands, calculating bets, and determining winners through electronic processes. This substitution of mechanical systems with automated digital management enables complex player-vs-player wagering with multiple betting rounds and card exchanges while maintaining system reliability and reducing operational complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
