Reigns

Reigns is arguably the most one-handed-friendly game on our list. It uses the “Tinder swipe” mechanic that many people are already familiar with and lets you use it to run an entire kingdom. Each card represents a scenario. For instance, you get a bishop asking for money, a general suggesting war, and a peasant complaining about taxes. You analyze each situation, and you approve or deny it with a thumb swipe. 

Every decision nudges four hidden meters representing the church, the people, the army, and the treasury. Let any of them max out or bottom out, and your reign often ends in a ridiculous way. Then you pop back in as the next monarch and keep going. Rounds are short, snappy, and perfect for quick one-handed sessions where you might get interrupted at any moment.
