Solution Overview

Problem

Conventional slot machines have predetermined paytables and winning combinations, limiting player excitement and enjoyment as they offer fixed average expected payback percentages, which do not vary during gameplay.

Innovation Solution

A gaming device that allows players to select or modify paytables, providing multiple paytables with different average expected paybacks, volatilities, symbol sets, and winning combinations, enabling players to change the paytable during gameplay based on their wagers or triggering events.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional slot machines use predetermined paytables, then the game operation is simple and reliable, but player excitement and enjoyment are limited due to fixed average expected payback percentages

Engineering Contradiction:
Improvepaytable variabilityVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic paytable selection where the paytable is no longer fixed but can change during gameplay. The system allows switching between multiple paytables with different average expected payback percentages, volatilities, and symbol sets based on triggering events or player choices, making the game adaptable and exciting while maintaining manageable complexity through structured transition rules

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key game parameters by allowing the paytable itself to be variable. Different paytables have different parameters including average expected payback percentages, volatilities, symbol sets, and winning combinations. The system can switch between these parameter sets dynamically, providing variety and player engagement without requiring complete redesign of the game structure

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple paytables with different average expected paybacks are offered, then player excitement and potential rewards increase, but the game complexity and number of elements increase

Engineering Contradiction:
Improvepaytable selectionVSAvoidnumber of paytables
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the paytable system into multiple distinct paytables, each with its own characteristics (average expected payback, volatility, symbol set). This segmentation allows the game to offer variety and player choice while managing complexity by treating each paytable as a separate, self-contained module with defined transition rules between them

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gaming device is designed with multi-functionality to handle multiple paytables. A single game platform can switch between different paytables with varying parameters, making the system universal enough to accommodate diverse paytable configurations without requiring separate hardware or software systems for each paytable type

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An apparatus and method for a game including a plurality of paytables, wherein each of the paytables has an average expected payout. The gaming device initially employs a default paytable and enables a player to cause the gaming device to change the employed paytable. If the player chooses to cause the gaming device to change the employed paytable, the gaming device randomly selects another paytable from the plurality of paytables and determines a game outcome based on the randomly selected paytable. If the player does not choose to cause the gaming device to change the employed paytable, the gaming device determines a game outcome based on the default paytable. In one embodiment, when a player chooses to cause the gaming device to select another paytable, the player has a chance to obtain a paytable that includes higher or better awards.
