It is decided before starting the game if it is to be played using the symbols or the numerical values, according to the ages and skill levels of the players. A game round is started by the youngest player. When comparing cards against each other the greatest numerical value or amount of symbols on the attribute compared beats the cards of the other players. The winner of a round collects all the cards and places them in his or her victory stack face up. The winner of the round continues the game, beginning a new round. The Asteroid, Volcano and Earthquake special cards always beat other cards automatically.
In the event of draw when comparing an attribute on the cards, the other attributes are compared against each other, starting from the top: e.g., if lengths compared are equal, weights are compared; if speeds are equal, lengths are compared. If the best cards to compare are equally strong each player gets to keep their card.
When all the cards have been played and placed into victory stacks, the number of cards in each victory stack is measured by either comparing the heights of the stacks of each player or by counting the cards. The winner of the game is the player that managed to collect the most cards in his victory stack.
The cards are dealt evenly face down among the players. The cards are not to be looked at or picked up. The youngest player begins the game by picking up the top card of his deck and placing it on the table, face up. Then the player decides whether to play the length, weight or speed of the card. The other players then pick the top cards of their decks, and the number of symbols concerning the attribute played are compared. The winner of the round begins the next round.
3 – 10 cards are dealt to each player. Cards are played one by one from their hands until the hands are empty, at which point new cards are dealt from the deck to each player as long as there are cards in the deck.
The starting player places a card of face down on the table, stating which attribute is to be compared. The other players then select their cards, placing them face down on the table as well. The cards are revealed at the same time.
Four cards are dealt to each player. Players may begin a round or respond by playing more than one card at a time, if all the creatures played belong to the same clan (colour group). The special cards and Dimetrodon are clanless cards. Cards without a clan symbol are played one at a time.
Players place their card(s) to be played on the table one player at a time, proceeding clockwise, and when done the cards are revealed at the same time. The numerical values compared are added together, e.g. the speeds 40 km/h + 45 km/h of the two cards played equal 85 km/h. The highest numeric value or the sum of numerical values wins the round.
Cards are then drawn from the deck so that each player always holds four cards in their hand for the duration of the game as long as there are cards in the deck. The player to draw first is the player that startedthe previous round, and the drawing of cards proceeds then clockwise. The winner of the last round collects the leftover cards in the other player’s hand.
The game is at its most tactical when playing The Multi-card Game and The Clan Game with two players! Reducing the number of special cards in the deck also makes the games somewhat more tactical.
