How to play Imperium: Horizons Solo

About Imperium: Horizons, from BoardGameGeek:

In your hands lies the destiny of one of the most storied peoples of history. Under constant threat of attack, you must conquer new lands, oversee dramatic scientific and cultural advances, and lead your people into the era of empire. Expand too rapidly and unrest will bring your civilization to its knees; build up too slowly, however, and you might find yourself a mere footnote of history. As one of fourteen radically asymmetric civilizations, you will compete to become the most dominant empire the world has ever seen. Imperium: Horizons is a standalone game that contains the Abbasid, Aksumite, Cultist, Gupta, Inuit, Japanese, Magyar, Martian, Mayan, Polynsian, Sassanid, Taino. Tang , and Wagadou civilizations. Each makes for a unique and challenging opponent in both multiplayer and solo games. Fully compatible with Imperium: Classics and Imperium: Legends for those wanting to expand their pool of civilizations even further, Imperium: Horizons also incorporates a new trade module that allows players to recreate all the intrigue, wealth generation, and dynamic politics of a thriving economy. The game is played in a series of rounds. Each round starts with the player to the left of the solstice card taking their turn and then turn order proceeds clockwise. On each turn, players will activate, innovate, or revolt. Once you have finished resolving your action, you will clean up. After you have cleaned up, the player to your left takes their turn. If the solstice card is between you and the player to your left, the round ends. Play continues until either scoring or collapse is triggered, which ends the game. The player with the most victory points wins. -description from the publisher
