GIST Scientists Develop Model that Adjusts Videogame Difficulty Based on Player Emotions

Published

Reading Time: 2 minutes

Appropriately balancing a videogame’s difficulty is essential to provide players with a pleasant experience. In a recent study, Korean scientists developed a novel approach for dynamic difficulty adjustment where the players’ emotions are estimated using in-game data, and the difficulty level is tweaked accordingly to maximize player satisfaction. Their efforts could contribute to balancing the difficulty of games and making them more appealing to all types of players. 
 
Difficulty is a tough aspect to balance in video games. Some people prefer videogames that present a challenge whereas others enjoy an easy experience. To make this process easier, most developers use ‘dynamic difficulty adjustment (DDA).’ The idea of DDA is to adjust the difficulty of a game in real time according to player performance. For example, if player performance exceeds the developer’s expectations for a given difficulty level, the game’s DDA agent can automatically raise the difficulty to increase the challenge presented to the player. Though useful, this strategy is limited in that only player performance is taken into account, not how much fun they are actually having.
In a recent study published in Expert Systems With Applications, a research team from the Gwangju Institute of Science and Technology in Korea decided to put a twist on the DDA approach. Instead of focusing on the player’s performance, they developed DDA agents that adjusted the game’s difficulty to maximize one of four different aspects related to a player’s satisfaction: challenge, competence, flow, and valence. The DDA agents were trained via machine learning using data gathered from actual human players, who played a fighting game against various artificial intelligences (AIs) and then answered a questionnaire about their experience.
Using an algorithm called Monte-Carlo tree search, each DDA agent employed actual game data and simulated data to tune the opposing AI’s fighting style in a way that maximized a specific emotion, or ‘affective state.’ “One advantage of our approach over other emotion-centered methods is that it does not rely on external sensors, such as electroencephalography,” comments Associate Professor Kyung-Joong Kim, who led the study. “Once trained, our model can estimate player states using in-game features only.
The team verified—through an experiment with 20 volunteers—that the proposed DDA agents could produce AIs that improved the players’ overall experience, no matter their preference. This marks the first time that affective states are incorporated directly into DDA agents, which could be useful for commercial games. “Commercial game companies already have huge amounts of player data. They can exploit these data to model the players and solve various issues related to game balancing using our approach,” remarks Associate Professor Kim. Worth noting is that this technique also has potential for other fields that can be ‘gamified,’ such as healthcare, exercise, and education.
This paper was made available online on June 3, 2022 and will be published in Volume 205 of the journal on November 1, 2022.
Let us hope this study paves the way to games that any type of player, whether hardcore or casual, can enjoy!

Evoplay gives a seasonal twist to popular fishing series in The Easter Catch

Published

Reading Time: < 1 minute

 

Evoplay, the award-winning game development studio, has reimagined one of its most popular fishing-themed slots The Greatest Catch with latest seasonal release The Easter Catch.

Keeping the original’s well-loved mechanics, this special edition introduces a fresh Easter-themed design, adding a seasonal feel while delivering the same exciting gameplay.

Played on a 5×3 reel layout with 10 paylines, the game introduces bonus symbols, which can land anywhere in the base game.

Three or more scatters activate the Free Spins feature, awarding 10, 15, or 20 Free Spins, depending on the number of triggers.

During Free Spins, Wild symbols substitute for all others and activate buoys on the progress bar. For every four buoys collected, 10 additional Free Spins are awarded, increasing the Fishing feature multiplier by x2 for the first four buoys, x3 for the second set, and x10 for the third.

The Fishing feature triggers when both Wilds and Fish symbols land on the reels, with Wilds collecting all fish values and adding them to the total win.

If a Wild lands without fish, the Dynamite feature may activate, replacing up to six random symbols with fish for extra winning opportunities.

Players can instantly access Free Spins with the Bonus Buy option, selecting between 10, 15, or 20 Free Spins for a direct route to the game’s key features.

Ivan Kravchuk, CEO at Evoplay, said: “With The Easter Catch, we wanted to bring a fresh, celebrational twist to one of our most popular titles while keeping the gameplay that players love.

“At Evoplay, we’re always looking for ways to refresh our portfolio with creative themes, and this Easter edition is the perfect way to celebrate the season while delivering the same great features that made the original a hit.”
