Cosmic Eidex is a board game released in 1998 for 3 players, 60 minutes per game, and ages 10 and up. It was designed by Urs Hostettler and its main mechanics are Variable Player Powers and Trick-taking.
Cosmic Eidex is an intriguing little trick-taking game for 3 players. The deck consists of 36 cards, 6 thru Ace, in four suits: Hearts (red), Lizard (green), Raven (black) and Stars (yellow). The Cosmic characters are the heart of the game, providing each player with a special Cosmic power. Each player draws one randomly at game start. In Cosmic Eidex, the idea is to take either the most points or the least points (designated by the trump and rank of the cards that you take each hand), to earn a victory point. If in a hand, one player exceeds 100 card points, then the other two players get 1 victory point each. If one player takes all of the tricks, she receives 2 victory points. Seven victory points wins the game. Cosmic Eidex is a mutation of the ages-old Swiss trick-taking card game Jass. Like Skat, the traditional German trick-taking card game, it is a three-player game. The Cosmic-like powers each player is given are relatively weak. Most allow the player to break one of the rules once per game (before, during or after), some can be used multiple times. You don’t need to know every characters' powers, just the powers of the three characters used in the current game. There are as many character/power possibilities as there are cards, but wise card play usually outweighs their influence.
Cosmic Eidex supports 3 players according to the catalogue. This is the publisher’s listed player count, so the game is designed for exactly that number of participants. Variants for other group sizes, if any, are described in the rulebook of your edition, so check it before setting up a different configuration.
The listed playing time for Cosmic Eidex is 60 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Cosmic Eidex for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Cosmic Eidex has a complexity rating of 2.7 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
