Solution Overview

Problem

Conventional video poker games do not optimize the initial hand for maximum expected value before allowing players to discard and replace cards, leading to suboptimal winning combinations.

Innovation Solution

A gaming system that determines if a 'dream card' will be used, selecting the last card of the initial hand to combine with other randomly selected cards for the highest possible expected value, allowing players to discard and replace cards based on this optimized hand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the last card of the initial hand is selected randomly in conventional video poker, then the game follows traditional poker rules, but the expected value of the initial hand is suboptimal

Engineering Contradiction:
Improveexpected value of initial handVSAvoidcard selection mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary evaluation of all possible card combinations before the player makes decisions. The processor calculates the expected value of each possible fifth card and selects the optimal card in advance, allowing the player to make informed decisions based on pre-optimized hand configurations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a virtual model of the poker game where multiple scenarios can be simulated and evaluated. By copying the game logic into software, the processor can calculate expected values for different card combinations without affecting the physical game flow, selecting the optimal card based on these simulations.

Inventive Principle:
Principle #26Copying

2Productivity

If the gaming system calculates and selects the optimal fifth card based on expected value, then the player's winning probability increases, but the game complexity and processing requirements increase

Engineering Contradiction:
Improvewinning combination rateVSAvoidprocessing system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual card selection and traditional random dealing with an automated electronic processing system. The processor automatically calculates expected values and selects optimal cards, substituting mechanical randomness with computational optimization while maintaining the appearance of traditional poker gameplay.

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

Solution Approach 2:

The system changes the parameter of card selection from random to optimized based on expected value calculations. By modifying how the fifth card is selected (from random dealing to calculated optimization), the system improves hand quality while the processing power handles the increased computational requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

A gaming system, a gaming machine and a method is provided having a Five Card Video Draw poker game with a single hand or multiple hands. The gaming system or gaming machine first determines whether a dream card is going to be used in a particular round of play or a dream card is used on every hand. If the dream card is going to be used, then the last card of the initial hand is chosen so that, when the last card is combined with the other randomly selected cards of the initial hand, the initial starting hand will have the highest possible expected value.
