The tutorial is the initial experience designed to introduce players to Hearthstone. It is composed of six 'missions', and must be completed before the player can play Hearthstone properly. The tutorial comprises a kind of introductory game mode with reduced gameplay and helpful instructions. The tutorial can only be played once.
Each 'mission' takes the form of a regular battle against a special enemy hero. The player controls Jaina, and the story follows her as she learns the basics of Hearthstone. Compared to normal play the tutorial is heavily directed, with the player's actions limited to a few possibilities. Basic game elements are added with each mission, slowly introducing the basics with helpful tips and instructions.
Each mission also features substantial dialogue between Jaina and her opponent. These opponents are unlike regular heroes, with unique abilities, cards and soundbites, and cannot be selected by players in the rest of the game. All of these characters are however available to collect as minion cards, with the exception of Hemet Nesingwary.
The ability to replay the tutorial has been requested by some players, as has the introduction of a range of tutorials designed to teach more advanced aspects of gameplay. Blizzard have indicated that they may be interested in these possibilities, although no plans have yet been announced.
