Measuring the success of an arcade game machine involves analyzing several critical metrics to ensure profitability and player satisfaction. Here are the most important ones:

1. Player Engagement: Track the number of plays per session, average playtime, and repeat visits. High engagement indicates a compelling game experience.

2. Revenue Generation: Monitor gross earnings per machine, cost per play, and overall profitability. This reflects the financial viability of the game.

3. Player Retention: Measure how often players return to the machine. Strong retention suggests long-term appeal.

4. Maintenance Costs: Evaluate repair frequency and downtime. Lower costs mean higher operational efficiency.

5. Customer Feedback: Collect player reviews and ratings to gauge satisfaction and identify areas for improvement.

By focusing on these metrics, arcade operators can optimize their game offerings and maximize success.
