U.S. Patent No. 9,649,568 (the ‘568 Patent) relates to difficulty levels of gameplay in a video game. In order to improve playtime in a video game it is normally necessary to simply develop new levels for the game. The ‘568 Patent attempts to address this problem in a more cost-efficient manner. Developing new levels may be costly, but the ability to dynamically adjust the difficulty of existing levels may allow for new playing experiences. As more people play a selected level the overall difficulty is increased. When a player attempts a level a selection of points is allocated from the player to the level they are playing. If they complete the level they are awarded the pot of points, but if they fail then another player may attempt the level to earn the available points. These systems work together to increase engagement and playtime of video games without having to develop new content entirely from scratch.
An object of the present invention is to provide a high-preference game system that can reduce a game development burden of a game system operator, can increase the desire of a player to iteratively play a game, and enables a player to play a game without aversion.
