To succeed in Reigns, maintain balance among the four meters: church (✞), people (⚇), army (♖), and treasury ($). Each decision impacts these meters, and if any meter becomes fully empty or full, your reign ends. Pay attention to the dots above cards when swiping—they indicate the magnitude of impact on each meter. For example, aiding a witch might boost the people's meter but lower the church's. To extend your reign, avoid extreme decisions early on and learn from past reigns, as the game logs choices on a linear timeline. To unlock special objectives like tricking the Devil, follow specific card sequences, such as saying 'No' to most requests after receiving the death wish curse until you encounter the dungeon or specific characters.
