Designing arcade machines for retirement homes presents unique challenges to ensure they are engaging, accessible, and safe for elderly residents. Key challenges include:

1. Accessibility: Controls must be easy to use for seniors with limited mobility or dexterity, requiring larger buttons, simplified interfaces, and adjustable seating.

2. Cognitive Engagement: Games should stimulate memory and problem-solving without being overly complex, balancing fun and mental exercise.

3. Safety Concerns: Machines need sturdy construction, non-slip surfaces, and minimal tripping hazards to prevent accidents.

4. Social Interaction: Multiplayer options encourage socialization, combating loneliness while fostering friendly competition.

5. Durability and Maintenance: Equipment must withstand frequent use and be easy to clean or repair in a communal setting.

By addressing these challenges, arcade machines can become a valuable source of joy and activity for retirement home residents.
