The Aztecs are under attack by alien invaders! Try to save as many Aztecs as possible from the alien invaders. In Space Aztecs you have to be smart, cunning, sneaky and sneaky.

Each turn, players choose a card from the piles around the sundial and all players play that card simultaneously. The order of play depends on the time shown on the cards. The earlier the time, the sooner you can play. The person with the earliest time also becomes the starting player in the next round. Build up your city with this and try to protect your inhabitants against an alien attack.

There are various card families, each with their own way of scoring points or a specific effect, such as using a flying saucer attack. The game ends when a certain number of card piles around the sundial are empty or a certain number of flying saucer attacks have been played.
