2. Engagement: High interactivity and immersive gameplay keep users motivated and focused on the learning process.

3. User-Friendly Design: Intuitive controls and clear instructions are essential to accommodate diverse age groups and skill levels.

4. Feedback Mechanisms: Real-time feedback helps players understand their progress and areas for improvement.

5. Durability and Safety: Machines should be robust for high usage and designed with safety in mind, especially for younger users.

By focusing on these aspects, arcade machines can effectively serve as powerful tools for education and training.
