About Twenty One Points

Twenty One Points is a blackjack duel where you manage risk, build a deck and spend Mana on skills that can change your hand, the deck order and the fight. Aim for Cap without Busting, weighing the chance of improving your hand against the value of using a skill.

Mana and skills

You manage Mana during battles and use it to activate skills. Awakened cards have suit-exclusive skills:

  • Burn Bridge: disrupt the opponent’s hand.
  • Undermine: discard and rewrite your own draw tempo.
  • Petty Theft: steal a key card from the opponent.
  • Star Gaze: look at and reorder the top of the deck.

Collect matching Artifacts to unlock four active skills:

  • Strong Exchange: spend Mana to swap hands with the opponent.
  • Reforge: spend Mana to discard a card from your hand and draw again.
  • Insight: spend Mana on a suit check to find a better hand.
  • Ingenuity: draw several cards and keep the best.

Deckbuilding and runs

Collect special cards and strengthen your deck with Awaken, Forge and Burn. You can combine Artifact passives with the four active skills to make different builds. In Roguelike mode, follow a map through battles, elite fights and Bosses, with shops and events along the way. Standard Mode offers a more direct duel for a quick run.

Choose a class

Each class starts with a suit focus and playstyle:

  • Xuanfeng Ke: Spades and offense.
  • Chishi Wei: Hearts and shields.
  • Duobao Xian: Diamonds and gold.
  • Yantian Ke: Clubs and Mana.
  • Junheng Shi: balanced across all four suits.
