The elderly population faces numerous motor and cognitive challenges that can intensify with age. These challenges include a decline in memory and attention and a weakening of motor skills. To prevent age-related regression and improve quality of life, seeking effective development solutions is essential. Our goal was to create a developmental game in Unity that develops the motor and cognitive skills of the elderly. During the design and development of the game, those tasks and challenges were implemented, which aided in improving fine motor skills, coordination, memory, and attention. The software includes several smaller games and tasks designed to stimulate different brain functions, such as thinking, memory, problem-solving, and attention. The goal of creating this game was to provide older people with a fun and motivating tool that helps them stay active; by offering them such a game, we allow them to maintain both their motor skills and cognitive abilities enjoyably, thereby improving their quality of life. In addition to offering a motivating user experience, the game specifically targets cognitive domains such as working memory, attention, and problem-solving, as well as fine motor control. These skills were chosen based on cognitive aging literature, which highlights their relevance in maintaining independence and mental flexibility in older adults. Theoretical foundations for this design are drawn from recent studies on cognitive stimulation in aging populations and usability-centered game-based interventions.
