Electronic Gaming Symbol Hold and Re-Spin RTP Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic gaming systems struggle with holding and shifting output symbols across different games while maintaining Return to Player (RTP), efficiently communicating active reels and output symbols, dynamically determining reel strips, and controlling RTP during symbol transitions.
Innovation Solution
Implementing a system where certain symbols are held across multiple game plays, using data structures and weighted tables to determine symbol positions, and employing animations to clearly communicate game mechanics, including re-spin games triggered by trigger symbols, with RTP maintained through random determinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If output symbols are held across multiple game plays, then symbol management efficiency is improved, but game complexity increases
Solution Approach 1:
The patent segments the reel system into active reels and inactive reels, and divides symbols into output symbols that are held across plays and non-output symbols that are replaced. This segmentation allows efficient symbol management by treating different symbol types differently, reducing the complexity of tracking all symbols across multiple plays.
Solution Approach 2:
The patent implements dynamic control where the system automatically determines which symbols to hold and which to replace based on game state. The processor dynamically adjusts reel spinning based on whether output symbols are present, creating adaptive gameplay that maintains efficiency while managing complexity through automated decision-making.
2Adaptability or versatility
If trigger symbols initiate re-spin games, then player engagement is improved, but game duration increases
Solution Approach 1:
The patent implements periodic re-spin games triggered by trigger symbols, where the re-spin sequence repeats until a stopping condition is met. This periodic action maintains player engagement through repeated gameplay cycles while naturally limiting duration through the termination condition, balancing engagement and time management.
3Reliability
If RTP is maintained through random determinations, then game fairness is improved, but control precision decreases
Solution Approach 1:
The patent uses parameter changes in the form of weighted probability tables that define different RTP levels. By switching between different weight configurations based on game state or player selection, the system maintains fair random determinations while achieving precise RTP control through mathematical weighting rather than pure randomness.

AI summary
An electronic gaming system is described. The electronic gaming system is configured to for a first play of the electronic game, cause a subset of reels to spin. The electronic gaming system is also configured to, based on at least one output symbol being displayed for the first play, cause initiation of a second play of the electronic game wherein the at least one additional output symbol is held and not replaced for the second play. The electronic gaming system is also configured to, after a last play, cause an output amount associated with displayed output symbols to be provided.
