Planetopia is a space deck building game where players each embody a planet and will optimize their hand to achieve the most interesting combinations to win the game.

The game goes clockwise,each player taking one turn at a time. During his turn a player has the choice among the following actions:

Mandatory action to choose among:

 Take a Cosmos card: Take a Cosmos card from the common trail. The rightmost card is considered to be closest to your planet, so you can take it without spending an Atom token. On the other hand, if you choose to take a card farther away from your planet, you will have to spend an Atom token on each card to the right of the chosen card. The chosen card then joins your hand, you can only apply its effect once you play it. Once the card is taken, slide the remaining cards to the right to fill the empty space. Then draw a new Cosmos card and add it to the left end of the row so you have 5 cards available again.
 Play a card: Play a card of your hand face up in front of you and apply its effect. Most of the time the Cosmos cards can accommodate new residents on your planet, then take the Alien tokens corresponding to the icons on the card played and place them on your game board. If you end up with more Alien tokens than your board can welcome, discard the token(s) of your choice without obtaining Atom token(s) in exchange. If you play the last card you had in hand, recover all your cards at the end of your turn.
 Recover cards: Collect in your hand all the cards played face up in front of you.

On top of your mandatory action you can make another optional action to choose between:

 Atomize: You may decide to discard one or two of the residents of your choice from your planet, receive an Atom token for each discarded Alien token.
 Make a combo: Discard the Alien tokens corresponding to the pattern on the Prestige card and take it. Keep it face up in front of you. Some cards can also recover special tokens.

You can therefore do a maximum of two actions per turn: one mandatory and one optional, in the order of your choice.

The game is played in as many rounds as necessary for a player to score 25 Prestige points. The player with the most points is then declared the winner, her Planet is the most remarkable of all the Galaxy!
