Designing an arcade machine for casual players requires a focus on accessibility, simplicity, and engaging gameplay. Here are the key considerations:

1. User-Friendly Controls: Casual players prefer intuitive and easy-to-learn controls. Avoid complex button layouts and opt for simple joystick and button configurations.

2. Short Play Sessions: Design games with quick, rewarding gameplay loops. Casual players often enjoy short bursts of play rather than lengthy sessions.

3. Attractive Visuals: Bright colors, bold graphics, and nostalgic retro designs can draw casual players in and enhance the overall experience.

4. Low Difficulty Curve: Games should be easy to pick up but offer gradual challenges to keep players engaged without frustration.

5. Durable and Comfortable Design: Ensure the cabinet is sturdy and ergonomic, with a comfortable height and spacing for players of all ages.

By prioritizing these elements, you can create an arcade machine that appeals to casual gamers and encourages repeat play.
