Game Machine Symbol Movement Path and Lottery Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game machines either fail to prevent player boredom by maintaining equal symbol probabilities or introduce predictability in game outcomes due to limited symbol movement directions, making it easy to anticipate winning patterns.
Innovation Solution
A game machine with a lottery region featuring cells where symbols are determined by lottery and moved along a path with two directions, making it difficult to predict the final symbol arrangement and introducing bias to player expectations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If symbols are determined by lottery with equal probability, then player boredom is prevented through variety, but player expectation becomes equalized and predictable
Solution Approach 1:
The patent applies asymmetry by changing the probability distribution of symbol determination. Instead of equal probability for all symbols, the system uses asymmetric probability weights where certain symbols have higher or lower chances of appearing. This creates unequal expectation among symbols, making it harder for players to predict outcomes while maintaining variety through the lottery mechanism.
2Device complexity
If symbol columns move in one direction only, then the mechanism is simple, but symbol prediction becomes easy reducing gameplay interest
Solution Approach 1:
The patent applies dynamics by making the symbol column movement direction changeable rather than fixed. The system dynamically adjusts the movement direction of symbol columns during gameplay, allowing them to move in multiple directions (up, down, left, right) based on control signals. This dynamic behavior prevents players from easily predicting final symbol positions while maintaining a relatively simple underlying movement mechanism.
3Device complexity
If the movement path contains only one direction, then the control mechanism is simple, but the game result becomes predictable
Solution Approach 1:
The patent applies dimensionality change by introducing multiple movement directions for symbol columns. Instead of restricting movement to a single linear direction, the system enables movement across multiple dimensions (vertical and horizontal directions), creating a two-dimensional movement space. This increases the complexity of predicting final positions while the control mechanism remains manageable through directional control signals.

AI summary
A game machine uses a lottery region containing the cells, provides a game opportunity that changes symbols on the cells by causing the symbols of a symbol group to appear on the portion of the cells, determines by lottery, at least a portion of the symbols which should constitute the symbol group, causes at least the portion of the symbols constituting the symbol group to appear in the lottery region based on a lottery result so as to change at least the portion of the symbols arranged on the cells by moving the symbol group including the symbol determined by the lottery result on a movement path containing two directions and stopping the symbol group so that at least the portion of the symbols of the symbol group is arranged on the cells, and determines a prize winning based on the symbols arranged on the cells by the symbol group.
