You and your fellow players are enthusiastic and curious astronomers, determined to explore and understand the constellations of the mysterious night sky. You are willing to help each other and share your discoveries, but in the end only one of you will become famous enough to be remembered throughout history.

Astra is a clever mix of tactics and strategy, with streamlined and intuitive rules that make it easy to pick up and play quickly. A game of Astra consists of a number of player turns until a certain number of Constellation cards are drawn, at which point, after an endgame count, the player with the most Fame points wins.

During your player turn you can choose to observe or rest.

The Observe action allows you to spend Stardust to discover stars on the Constellation cards with your marker. You may only mark stars in a straight solid line, but you may spend telescope tokens to start new observations. Once you mark the last star in a constellation, you'll grab the map of the night sky, granting you a powerful reusable ability for the rest of the game. But other players also benefit from the discovery: based on the number of stars they have marked, they can choose one of the immediate benefits of the card (Boons) the moment it is discovered.

The Rest action not only allows you to replenish your Stardust to its maximum capacity, but also reactivates all your card abilities corresponding to the currently active Sphere. Your card skills are very powerful and strategically possible, so a well-timed rest action can give you a huge advantage.
