The basic set up of the game is to place one card in the center, called the Inner Core. The six face down cards around it are called the Outer Core. Players draw a card to see who goes first. Players are dealt seven cards each.
On a players first turn, they can heat or cool the planet by adding cards in number sequence. However many they place, gives them the option of flipping outside panels. The first connection of inner to outer core must match number sequence. Note: Sequence is 2-K and King returns to card 2, as the Ace card is considered the Alien card. In this example, the player has luckily connected the 4 and 3 between inner and Outer Core. They must place a 4 or 2 (which they have) on the 9 to continue the sequence or risk taking all of the Outer Core.
Here we see that the player flipped an Ace card when opening an Outer Core panel. The player must take all Outer Core cards, except for the Ace which is returned to the bottom of the deck. This is to balance the effects of the Ace so it does not jump around, causing players to constantly make each other draw. If a player completes the Outer Core of the planet, they must choose a player to take all of the Outer Core cards.
