SteamDeck TOP Played list.
In the past week, I've already spent dozens of hours on the new DLC of Brotato and Vampire Survivors, it's so addictive! In a few weeks, there will also be the official releases of DarkchaserBattletide and Jotunnslayer. There are just too many survivor-like games to play!
ITT: people who think Balatro is so good they don't even need to spell it right. They're right though.
Now that I have your attention, check out Dungeons & Degenerate Gamblers if you prefer blackjack over poker. Or Solitairica if you enjoy Solitaire. Should run like a dream on Steam Deck as well.
