Designing an arcade machine for mobile use requires careful planning to ensure functionality, durability, and an engaging user experience. Here are the key considerations:

1. Portability: The machine should be lightweight and compact, with easy-to-move features like wheels or foldable designs.

2. Durability: Materials must withstand frequent transport and usage, such as reinforced frames and scratch-resistant surfaces.

3. Power Supply: Opt for battery-powered or energy-efficient options to enable gameplay without constant electrical access.

4. User Interface: Ensure intuitive controls and a responsive touchscreen or joystick setup for seamless gaming.

5. Game Selection: Include a variety of classic and modern games to appeal to diverse audiences.

6. Connectivity: Offer Bluetooth or Wi-Fi for multiplayer options and updates.

By addressing these factors, designers can create a mobile arcade machine that delivers fun and convenience for gamers everywhere.
