Hearthstone: the legend of heroes of Warcraft is a free strategy card game on Windows system and iPad launched by Blizzard Entertainment. Players can choose to play one of the nine heroes in the series of Warcraft, and take turns to use the cards in their own decks, so as to cast powerful spells, use the weapons and skills of heroes, or summon powerful followers to help them destroy their opponents.

At first, the game will randomly select 4 (back hand) or 3 (front hand) cards from the player's deck (30 cards), and then the player can replace some of them to complete the opening deck.

1 Mana Crystal will be automatically added every turn. Mana Crystal is a necessary unit for summoning cards, and will be automatically restored after the turn (the blue gem at the bottom right of the interface is Mana Crystal).

In addition to the follower card (the card with no round limit for attack and defense), the card also has a spell card, which is a consumable.

When a player has a large number of mana crystals, he can play the cards allowed by the mana crystals many times.

Different heroes have different skills. In addition to having public cards, they can also get special cards for heroes.
