Common Problems
- I am playing Casual and I don't see progress towards my achievements
- I finished Book of Heroes: Rexxar, got the achievement, but didn't receive the card pack
Achievements are broken up into categories and subcategories. The general Progression and Gameplay categories can be completed in Ranked, Arena, and Duels modes; they cannot be completed in Casual mode. Game Modes and Adventures categories can only be completed in their specified modes.
If you've been playing Hearthstone for a while and you already met the criteria, some achievements may be retroactively granted to you as soon as you log in. The displayed date of completion will be the day you first logged in after Madness at the Darkmoon Faire launched (the date the game granted you the achievement) and not the date when you actually completed the achievement.
Customer Support has no ability to grant achievements that were not granted in-game. To report a bug with an achievement, visit the Hearthstone Bug Report forums.
