Arcade machines thrive on player engagement, and tracking the right Key Performance Indicators (KPIs) is essential for maximizing profitability and user satisfaction. Here are the most common player engagement KPIs for arcade machines:

1. Playtime per Session: Measures how long players engage with a machine, indicating game appeal.

2. Revenue per Player (RPP): Tracks average spending per player, helping assess monetization effectiveness.

3. Repeat Play Rate: Shows how often players return, reflecting long-term engagement.

4. Coin Drop Rate: Monitors the frequency of coin or credit usage, indicating game popularity.

5. Player Retention Rate: Evaluates the percentage of players who return over time, crucial for sustained success.

By analyzing these KPIs, arcade operators can optimize game selection, pricing, and maintenance to enhance player experience and revenue.
