An unknown phenomenon is shortening the lifespan of all humanity. An exploration team travels to the Eternal World in search of answers, and there they encounter mysterious mystical entities called Eternals. Will this exploration team be able to solve the mystery of life and return to their world?
Eternal Decks is a cooperative game in which players try to complete the phase's objectives before one of them is unable to take any action. Players begin the game with five cards in their deck, but will quickly try to acquire more cards from the various Eternals (game characters), each of whom has their own unique deck of eight cards. On your turn, you must take one action:
- Play a card (in the field, in the river or using a skill).
- Create a jewel.
- Give a letter to a teammate.
There are restrictions on playing a card. The three rows on the field cannot have cards of the same color or number next to each other. Additional restrictions apply to a row depending on the phase you are playing. Jewels are used to negate the negative effects caused by Eternals.
The game has six stages, and in them you will have to accumulate points, survive in a ghost town, navigate a maze, defeat a boss and much more to win the game.
