In Brawl, two players fight to the finish. You don't win until your opponent is knocked out. Each round, both players play a card from their hand face down, then they flip over and execute the card played in the previous round. The five cards (Block, Dodge, Jab, Hook, and Roundhouse) allow the players to use offensive and defensive techniques and combinations to reduce their opponents health to 0. If your health reaches 0, you're knocked out and you lose.
