Arcade machines, especially coin-operated ones, are designed to manage game session time limits and idle timeouts efficiently to maximize revenue and ensure fair play. Here’s how they handle these features:

1. Coin-Based Time Limits: Traditional arcade games often use a timer tied to the number of coins inserted. Each coin grants a set amount of playtime, and the game ends when the time expires unless more coins are added.

2. Idle Timeouts: To prevent machines from being occupied without active play, arcades implement idle timeouts. If no input is detected for a certain period (e.g., 30-60 seconds), the game resets or displays an attract mode to invite new players.

3. Software-Controlled Sessions: Modern arcade machines use software to dynamically adjust session lengths based on game difficulty or player progress, ensuring balanced gameplay and encouraging replayability.

4. Attract Mode: When idle, arcade machines often switch to a demo or attract mode, showcasing gameplay highlights to draw in players while conserving energy.

These mechanisms help arcades maintain turnover, reduce downtime, and enhance the player experience.
