Steam Deckbuilders Fest: up to 85% off Balatro, Slay the Spire, and 2,800 more
Steam's Deckbuilders Fest is live right now, offering discounts of up to 85% on card-building games through May 11, 2026. More than 2,800 titles are included, spanning roguelike deckbuilders, card battlers, and tactical card games. The timing is no accident — the genre is riding a genuine wave after Balatro hit 5 million sales by January 2025 and Slay the Spire 2's Early Access launch crashed Steam servers under the weight of player demand.
The genre moment
Deckbuilders have gone from niche to mainstream faster than almost any other PC gaming category. Balatro — a poker-themed roguelike from a solo developer — won Best Independent Game and Best Debut Indie Game at The Game Awards 2024, putting card-building on the same stage as big-budget releases. Slay the Spire 2 then demonstrated just how hungry the audience still is. If you've been meaning to try this style of game, a sale with 2,800+ titles is a reasonable entry point.
The deals
The festival covers a wide range of price points and difficulty levels. Here are some of the more notable discounts active during the sale:
- Balatro — 20% off - Slay the Spire — 75% off - Marvel's Midnight Suns — 85% off - Cardboard Town — 80% off - Die in the Dungeon — 35% off - Dungeon Clawler — 35% off - As We Descend — 33% off - Death Howl — 25% off - Cat God Ranch — 40% off - ACE Strategy: Mecha Nova — 14% off
Balatro's modest 20% cut reflects its continued commercial momentum — it still sells well on PC and mobile. Marvel's Midnight Suns at 85% off is the steepest deal in the lineup, making it worth a look for anyone interested in superhero strategy with card mechanics layered in.
What to do
The sale runs until May 11, 2026 at 10 a.m. PDT. The full catalog is browsable directly on Steam, organized by sub-genre to make discovery easier. Several games also have free demos available during the festival window — useful if you want to try before you buy.
