Every card you lay down hits: number cards strike or heal, face cards burn the mana right out of your rival's pool. Play them one at a time, or chain a pair, a flush, a run — the bigger the hand, the harder it lands, and jokers slot themselves into your strongest combination.

Mana is the whole game. Small cards mint the most of it, so you are always choosing between a big hit now and the fuel for a bigger one later.

Spend it on Blade to sharpen a strike, Shield to soak one, and Swap to trade up to three cards out of your hand. Your hero is the other half of the deck.

Every portrait is a card you own, with its own trump suits, a favourite poker hand and one ULT charged by the cards you play — Strike, Poison, Mend, Bloom, Cleanse, Shackles or Thorns. Collect duplicates to star a hero up and open every duel with a fuller mana bank.

Play a quick match against the computer, pass the device for a local duel, or challenge a real opponent online. Take the long road through Adventures, where each chapter is a board-game maze of fights, chests, traps and mini-games leading to a boss; climb the endless Gauntlet; or take the daily challenge, where both sides get the same freshly-rolled epic set — no gear, no excuses.
