Each player is assigned an element, Water or Earth. Players takes turns placing cards representing their element until the board (called the Vacuum) is full.

Each card can have one of three temperatures chosen at random: Normal (green border) or one of two extremes, Hot (orange border) or Cold (blue border). When placed on the board a card's temperature is transferred to any adjacent cards.
A normal card has no effect on adjacent cards
Opposite extremes cancel each other out and normalize the temperature of both cards
Identical extremes result in the removal of the adjacent card and normalization of the incoming card
Adjacent normal cards assume the temperature of the incoming card, normalizing the incoming card
If there are no adjacent cards then there is no change to the incoming card's temperature (eg. a Hot card stays hot)

A player may sacrifice an extreme card to normalize an opposing extreme already on the board.

Players may also randomly draw an Ice Age or Inferno Event Card. The player drawing an Event Card loses their turn and the entire board is affected by the extreme temperature change as if they were adjacent to an incoming card of the event's temperature.

The game is over when the board is full. The player with the most Normal cards on the filled board wins. In the event of a tie, the player with the most cards overall wins.
