Collect, enhance, and build your deck. Battles run automatically in this idle card game. Your only role is choosing which cards to use. In a stagnant world ruled by eight races and Kings, reshape conflict through deck building and move civilization forward. Beyond idleness lies strategy—and story.
――Build your deck. Watch the battle unfold. Civilization begins to move forward through your choices.

Card Idle : Rise of the Eight is
an idle card game where battles unfold automatically,
allowing you to focus on collecting, enhancing, and building your deck.
As a player, you will:
Open card packs
Purchase and enhance cards
Build strategic decks
No manual combat is required. All decisions are concentrated in preparation.

Battles are meant to be watched.
Victory and defeat depend on
which cards you choose and how you construct your deck.
Observe the results,
then rebuild your deck for the next challenge.
Through repetition,
your strategy deepens and the world moves forward.

――Why did civilization come to a halt?
A world where civilization has stagnated due to endless conflict.
Across the land dwell
Humans, Beasts, Aquatic Folk, Machines, Undead, Demons, Fairies, and Dragons
—eight races in total.
Each race
raises its own ideals and power,
and reigns as a King (Boss).
The conflicts never cease,
and the world remains stagnant.

Then,
an Observer who has long watched over the world
awakens a single being.
It is you,
once known as the "Legendary Card Gamer."
The Observer declares:
"End the conflicts through cards,
and move civilization forward once more."
You are guided
to the central city on the surface, Eldenfort.

Eldenfort is
the starting point of every journey.
Here, you will:
Purchase cards
Open packs
Build your deck
Then set out across the world.
Across each land,
the Kings of the eight races await,
each carrying their own ideologies and circumstances.
In this world, conflicts are not decided
by individual skill or split-second decisions.
The accumulated ideologies, values, and structures
of each race determine the outcome of battles.
That is why you do not wield a sword.
You choose cards.
You construct decks.
Combat is fully automated.
You observe the results,
and apply them to your next preparation.
Your choices themselves
are what change the course of civilization.

The end of the story is not the end of the journey.
Rematches against the Kings at their full strength
Limit-breaking card enhancements
A collection system to gather every card
Stronger and more refined,
endgame content awaits as you complete your ultimate deck.
Enjoy idle games
Love deck building strategy
Enjoy fantasy worlds
Prefer strategy over constant action
Like steadily growing stronger
Beyond idleness lies strategy—and story.
