Kakao Games Corp. announced on the 5th that it has added a new mini-game and 'Dr. Ho's 7-Day Growth Guide' to its casual brain training game Oneuldoo Hodoo, alongside a revamp of the ranking system.
Developed by Beluga, a startup specializing in cognitive function assessment and treatment, Oneuldoo Hodoo is a game that manages five core cognitive domains: memory, attention (concentration), executive function, language, and visuospatial skills. The newly added 'Crush Line' is content designed to train visuospatial skills using various blocks.
Designed to help new users adjust to the game, 'Dr. Ho's 7-Day Growth Guide' awards reward items whenever missions are completed. The ranking system has been expanded to include a 'Hall of Fame' and individual rankings for each cognitive training casual game. 'Dr. Ho's Brain Story', which delivers brain training insights and update news, will also be featured continuously, covering topics such as cognitive psychology, short-term memory, and memorization techniques.
Oneuldoo Hodoo features intuitive gameplay and diverse content so that people of all ages can use it consistently in their daily lives. According to Kakao Games, each piece of content incorporates scientifically proven cognitive enhancement techniques. Users can manage their cognitive state and training progress through cognitive function measurements and training feedback.
The joint research on serious games between Kakao Games and Beluga has been conducted based on a business agreement signed in 2023. Professor Min Kyung-bok of the Department of Preventive Medicine at Seoul National University College of Medicine participated as a co-researcher in the study on dementia diagnosis, prevention, and management.
Prior to Oneuldoo Hodoo, the two companies introduced Brain OK, a dementia symptom detection game, in June 2024. Kakao Games explained that it has continued related research, with a paper proving the effectiveness of Brain OK's cognitive function measurement published in the medical journal Diagnostics.
