Hearthstone is an online TCG (Trading Card Game) that enables you to challenge anyone in the world to a card duel. It works like most of the TCG games out there, but Hearthstone made it easier even for beginners to understand. Winning the duel just means depleting your opponent's health (HP) to zero. Unlike other TCGs, depleting your deck does not make you lose the match. You just deal damage to yourself each turn you aren't able to draw anything from your deck. Both players will have their own heroes to use plus access to their specific hero powers. These powers or abilities can be triggered by clicking the hero ability icon just right beside the player's hero avatar. Hearthstone cards are divided into three categories: minions, spells, and weapons. These cards can be used when you have acquired enough mana equal to their usage cost. Attacking simply means clicking on your minion and directing its attack at your target. You can target an enemy minion or the hero directly. Spells also work the same way. Just choose the spell you want to cast and then choose the target you want to affect.
