It's an astronomy game. You need to obtain a certain amount of power to beat your opponent. You gain (or lose) power by picking cards. These are the card groups:

GAINERS (including stars, planets, comets, etc.)
LOSERS (including black holes, dark matter, brown dwarfs, etc.)
POWER (actions used when you have a certain amount of power)

Each player starts out with 50 power. You need 300 power to win. First, you shuffle the card deck (filled with gainers, losers, and power cards).

Example of gameplay:

Player 1 picks a brown dwarf. They lose 5 power. Player 1 45 power.
Player 2 picks exomoon. They gain 1 power. Player 2 51 power.
Player 1 picks galaxy. They gain 30 power. Player 1 75 power.
Player 2 picks planetary collision. This power card can subtract 20 power from Player 1 as long as Player 2 has 50 power. Player 2 51 power.

Player 1 picks black hole. They lose 20 power. Player 1 55 power.
Player 2 uses planetary collision. Player 1 loses 20 power. Player 1 35 power. Player 2 75 power.

Player 1 picks stellar collision. This power card can subtract 50 power from Player 2 as long as Player 1 has 100 power.

Player 2 picks nebula. They gain 20 power. Player 2 95 power.
