About This Game

The duel history never had

A Korean admiral. A Chinese warlord. A Japanese swordsman. A Roman gladiator.
They never met — until now.

PARAGON 21 is a duel card game where the greatest warriors of every age face each other across a single table. One hand of cards. One strike. One answer to a question people have argued about forever.

Twenty-one is your blade

Draw cards to reach exactly 21 and your art ignites. The fewer cards you use, the deadlier it lands. Just two cards is a blackjack — the heaviest blow in the game.

Every warrior has four distinct arts, one for each hand size. Yi Sun-sin's two-card strike is Myeongnyang. His five-card assault is the Battle of Hansan. Same twenty-one, different weight entirely.

Two cards they cannot see

You always hold two hidden cards. Swap them onto the table, pull a card back, rebuild your hand — none of it costs a turn.

Your opponent sees only how many you hold, never what they are. That gap is where the whole duel lives.

Push your luck, or walk away

Land a finisher and you can chain it. The limit climbs to 31, then 41. The multiplier grows with it. Miss, and half of what you banked comes straight back at you.

Stop and take the sure damage, or reach for the kill. That choice comes up every single time.

Every legend is waiting

Choose your warrior. The rest stand between you and the answer.

Each one commands men who will die before you reach them — foot soldiers, then captains, then the paragon himself. Cut through all of it, and one more legend falls behind you.

They start alone. By the end they bring a million. Your blade never changes. Only the count of the fallen does.

No gods. No magic. Only steel.

Every fighter here actually lived.
Every duel here never happened.

Only one can be left standing.
