Go to Settings in the app and tap "Reset Progress". This will clear all your XP, completed scenarios, and achievements. This action cannot be undone.

Rival Edge automatically uses your device's language setting. To change the language, go to your iPhone Settings → General → Language & Region → iPhone Language. The app supports English, Russian, French, German, Spanish, and Italian.

Your progress is stored locally on your device. If you have iCloud Backup enabled for the app, your data will be backed up with your device's iCloud backup. If you delete and reinstall the app, your progress may be lost unless you have a backup.

A Nash Equilibrium is a situation where no player can improve their outcome by changing their strategy alone. It's named after mathematician John Nash (1950). In the app, we highlight the Nash Equilibrium in each scenario to show you the "stable" outcome where both players have no incentive to deviate.

Stars are based on your score relative to the best and worst possible outcomes in each scenario:
• ⭐⭐⭐ 3 stars: Top 15% of possible scores
• ⭐⭐ 2 stars: Top 40% of possible scores
• ⭐ 1 star: Above bottom 35%
The "optimal" outcome depends on your opponent's choice — sometimes the Nash Equilibrium isn't the maximum score!

Absolutely! We love hearing ideas for new real-life scenarios. Email us at support@rivaledge.app with your suggestion. Include the situation, the key decision, and what game theory concept it might illustrate.
