Valve’s Steam Deck continues to strengthen its position in handheld PC gaming as its Verified compatibility system surpasses 25,000 confirmed titles, according to data compiled by third-party database SteamDB. The milestone reflects the number of games that Steam Deck owners can install and run with varying degrees of compatibility on the Linux-based SteamOS platform.
SteamDB’s breakdown shows 7,528 titles labeled “Verified,” indicating they run with no issues on the Steam Deck, and 17,527 games classified as “Playable,” meaning they run with minor quirks that do not significantly impact playability. These designations are part of Valve’s internal testing and certification process that tags games according to how smoothly they run on the handheld’s hardware and controller interface. Meanwhile, GamingOnLinux reports that just over 6,000 titles remain “Unsupported,” generally due to missing controller support, performance challenges on the AMD Zen 2 architecture, or incompatibilities such as kernel-level anti-cheat systems.
The achievement places Steam Deck confirmation for roughly a quarter of Steam’s overall catalog, which is estimated at around 120,000 games. Although the sheer volume of annual releases — often exceeding 20,000 new games per year — makes blanket compatibility an ongoing challenge, Valve appears to focus on prioritizing high-profile releases and popular titles to ensure the widest possible coverage for owners.
The Steam Deck Verified framework has proven influential beyond Valve’s hardware. Microsoft has introduced a similar Xbox Handheld Compatibility Program for Windows-based handhelds such as the Asus ROG Xbox Ally, borrowing the concept of categorizing game experiences by performance and usability on portable devices.
Nearly four years after its 2022 debut, the Steam Deck’s impact on PC gaming remains significant. It helped catalyze interest in portable PC gaming and established a compatibility standard that competitors now emulate. While Valve has yet to announce a direct successor, its expansion into adjacent hardware — including the Steam Machine desktop/console hybrid and the new Steam Frame VR headset — suggests ongoing development rooted in the ecosystem that the Steam Deck helped define.
