Slay the Spire 2 is demonstrating exceptional success, establishing itself as one of the most profitable indie games in history, largely due to its unprecedented conversion rate from wishlists to actual sales.
Within the first two weeks of its early access launch, this sequel has surpassed the Steam revenues of major indie titles like Hades 2 and Hollow Knight: Silksong. According to Alinea Analytics, the game has sold approximately 4.6 million copies, generating over $92 million in revenue.
The exceptionally high wishlist conversion rate is particularly noteworthy: 31% of users who added the game to their wishlist purchased it within the first week, a figure that climbed to 34% by the end of the second week. This is significantly higher than the typical 7-10% considered successful for such conversions.
Key factors contributing to its success include the long-awaited status of the sequel, the active engagement of developers Mega Crit with the gaming community, and a strong presence in the Chinese market, which accounts for over a third of the game’s audience.
Slay the Spire 2 entered early access on March 5, 2026, and is already a strong contender for one of the year’s leading indie hits.
