Arcana

A one-on-one card duel. You and your rival stake the same amount, and the winner takes the pot.

How a duel works

  1. Lock your stake

    You and your rival deposit the same amount into an escrow contract. It stays there until the match is settled.

  2. Duel

    Both players get the same 20-card deck. Turns last 45 seconds, so most matches end in under ten minutes.

  3. Take the pot

    The winner withdraws the pot minus a 0.5% fee. If no result arrives before the deadline, each player withdraws their own stake.

No wallet needed

Try a quick duel

Both heroes start with 10 health and 3 mana, so a match against the practice bot takes about two minutes. It runs on the same rules engine as the real game.

  1. Play a card by clicking it. Spells that need a target ask you to pick one.

  2. Attack by clicking one of your glowing minions, then an enemy.

  3. End your turn when you run out of moves. The first hero to reach zero loses.

The deck is sealed before the first card is dealt

Before the match, the server and both players each pick a secret seed and publish only its fingerprint, a SHA-256 hash. The shuffle is built from all three seeds together, so nobody can choose the order alone. When the match ends the seeds are revealed, and anyone can rebuild the shuffle and compare it with the cards that were drawn.

Late result, full refund
Every match has a settlement deadline. If no result is posted in time, each player withdraws their own stake without asking anyone.
You pull your winnings
Payouts wait in the contract until you withdraw them, so one blocked address can't hold up anyone else's money.
Same deck for both
No card packs and no upgrades to buy. The only edge is how you play.

Both decks, in order

Three secret seeds are hashed together, and the result decides the order of both decks.

Twenty cards, the same for everyone

Minions stay on the board and fight, spells happen once, and four keywords cover the rest: Swift, Guard, Ward and Reveal.
