How a turn works
Four rules. Everything else is on the cards.
You open with two cards
Your pile is at least ten martial artists deep. A battle starts with two of them in hand; the rest wait in the pile, in an order you cannot see.
One card a round
Each round you play a single card from your hand. That is the only restriction — no mana, no cost, no timer. Some cards put other cards into play, and that is exactly how a clan bends the rule.
One card drawn a round
A fresh card arrives at the start of every round. What you hold is what the road handed you, so the question is never “what do I have” but “what do I play first”.
Beat the grade before the rounds run out
Every card on the table is worth its grade, and abilities push that number up and down all game. Reach the stage's total within its rounds and the road opens.
Under Heavens is a card game set in the jianghu — the rivers and lakes where sects feud, wandering swordsmen sell their blades, and every clan believes its own manual is the true one.
You carry a pile of martial artists. Each stage asks for a grade you cannot reach by luck alone: you reach it by knowing what your clan is built to do, and by playing your cards in the order that pays.
Try a hand
The real engine, running right here.
A ten-card pile from one clan — two copies of each of its first five martial artists. Five rounds, one card a round, and a grade to beat. The clan you pick changes the whole problem.

The clans
Each clan plays one idea, all the way down.
A card’s clan tells you what it wants before you read a word of it. Learn one clan and you can guess the next card it hands you.
Mount Hua
Sword formation
The order you play in decides the cut. Each blade wants the right card before it, and a clean sequence turns a modest hand into a finished form.
Sword-Formation Elder 5
Each time you play another Mount Hua card, it gains +2 grade.
Wudang
Yin and Yang
The flow turns over with every card that enters play. Wudang is the clan that reads it — one line for Yin, another for Yang, and cards that climb with every reversal.
Purple-Cloud Elder 5 
While this is in play: if the flow is Yin, it gains +8 grade if you have not drawn a card this turn; if the flow is Yang, it gains +8 grade if you have not played a card this turn.
Shaolin
Pile and restraint
Monks grow with what your pile still holds, and reward the rounds you hold back. Patience is a resource the temple knows how to spend.
Temple Abbot 4 
At the end of your turn, if you have 5 or more cards in your pile, your other cards in play each gain +1 grade.
Tang Clan
Hidden weapons
Mark cards with poison and darts, then collect the debt when it suits you. Nothing the Tang Clan does looks dangerous until it already happened.
Silent Assassin 9 
When played, a Hidden Weapon marked card in play gains +5 grade.
Demonic Cult
Frenzy
A combo burst measured inside a single round. Every extra card you can unleash before the round closes makes the last one hit harder.
Blood-Sea Demon 6 
While this is in play, it gains +2 grade for each card you played this turn.
Blood Cult
Burning bright
Enormous the moment they arrive, and weaker with every round they stand. The Blood Cult is a bet that the fight ends before the price comes due.
Scarlet Fiend 16 
At the end of each round, this loses 3 grade.
What you can play
One engine, four ways to spend an evening.
Roguelike run
The Journey
Thirty stages, a shop between fights, treasures that bend the rules, and a pile that grows from the cards you choose to keep. One life. Re-drawn every run.
Asynchronous duels
The Contest
A weekly rule set, a fixed pile size, and a server-verified score. You are not waiting on an opponent's turn — you are answering their best attempt.
Seasonal events
Gatherings
Limited chapters with their own stories, boss encounters, sealed drafts and market days. They arrive, they matter, and they close.
Collection
The Roster
Every martial artist you have encountered, drawn by hand, with the exact wording of their technique. Pack odds are published from the same table that rolls them.

Before you download
Questions people actually ask.
How much does Under Heavens cost?
The game is free to download and free to finish. Optional purchases buy cosmetic card backs and card parcels; the odds for every parcel are published in the app before you spend anything.
Does it need an internet connection?
Yes. Under Heavens is an online game — your roster, journeys, contests and seasonal events live on the studio's servers, so a connection is required to play.
Do I need an account?
No. You can play signed out. Signing in is optional and goes through Apple or Google — there is no password to create — and it binds your roster and journeys to that account so a new phone or a reinstall can recover them. The Contest and cross-device play need it; nothing else does.
Is there an energy system or ads?
No. There is no energy, no timer between runs, no advertising, and no third-party tracking. You play as long as you want to.
Which languages does it speak?
English, French, Spanish, Japanese, Korean and Simplified Chinese — cards, rules text and story are all translated.
Do I need to know wuxia to enjoy it?
No. Every rule a card follows is printed on the card, and a guided first journey teaches the pile, the grade and the clans in a few minutes.
