Dynamic Symbol Replacement in Reel-Based Gaming Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional slot machines lack features that enhance player engagement and excitement, as they typically offer fixed symbol arrangements and limited winning opportunities, leading to decreased player interest and revenue for casinos.
Innovation Solution
Implementing a system that allows for dynamic symbol replacement on reels or matrices within video slot machines, enabling the creation of winning combinations by inserting predetermined symbols, thereby increasing player engagement and opportunities for winning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed symbol arrangements are used in slot machines, then the device complexity is low and ease of manufacture is high, but player engagement and winning opportunities are limited
Solution Approach 1:
The patent implements dynamic symbol replacement where predetermined symbols (such as wild symbols) can replace existing symbols on the reels after the spin outcome is determined. This dynamic modification of the symbol arrangement increases winning opportunities without requiring complex mechanical changes to the reel structure itself, as the replacement is achieved through software-controlled display manipulation.
Solution Approach 2:
The system pre-determines certain symbols as 'predetermined symbols' that have the capability to replace other symbols. These symbols are prepared in advance with special properties (such as wild symbol functionality) that enable them to substitute for any other symbol type, thereby creating additional winning combinations without requiring real-time complex decision-making during the spin resolution process.
2Adaptability or versatility
If dynamic symbol replacement is implemented, then player engagement and winning opportunities increase, but the device complexity and software requirements increase
Solution Approach 1:
The predetermined symbols serve multiple functions: they act as regular symbols that can contribute to winning combinations, and they simultaneously function as wild symbols that can replace any other symbol type. This multi-functionality reduces the need for separate symbol types and complex replacement logic, as a single symbol type can fulfill multiple roles in different contexts.
Solution Approach 2:
The system changes the state parameter of symbols by applying a 'replaced' flag or attribute to indicate which symbols should be replaced by predetermined symbols. This parameter change approach allows the system to manage symbol replacement through simple state modifications rather than complex structural changes, reducing overall system complexity while enabling dynamic symbol manipulation.
3Productivity
If predetermined symbols replace existing symbols to create winning combinations, then player excitement and revenue potential increase, but the fairness and randomness of the game may be compromised
Solution Approach 1:
The replacement of symbols by predetermined symbols is determined in advance as part of the game outcome calculation, before the player observes the results. The system pre-determines which symbols will be replaced based on the initial spin outcome and the positions of predetermined symbols, ensuring that the replacement process does not introduce additional randomness or unfairness, but rather reveals a pre-determined outcome.
Solution Approach 2:
The system provides visual feedback to the player by displaying the replacement process and highlighting the winning combinations that result from symbol replacement. This transparency in showing how predetermined symbols replace other symbols and create winning lines helps maintain player trust and perceived fairness, as players can see the logical progression from initial spin to final winning outcome.

AI summary
An embodiment may involve selecting a set of symbols associated with an outcome event of a reel-based game. The reel-based game may be executed on behalf of a client machine, and selecting the set of symbols may involve spinning a plurality of reels to determine the outcome event. The embodiment may further involve determining that the set of symbols includes a predetermined symbol on a designated reel and does not include any winning combination. The embodiment may also involve, possibly in response to determining that the set of symbols includes the predetermined symbol on the designated reel and does not include any winning combination, replacing one or more symbols in the set of symbols with predetermined symbols such that the symbol set after replacement includes a winning combination.
