Notes

Portal 2

$1.99 (80% off, was $9.99)

Valve's own physics-puzzle classic, and still one of the best co-op campaigns on Steam. It's also Steam Frame's first Playable-rated game , if you're curious how it'll run on Valve's unreleased headset.

INSIDE

$2.49 (90% off, was $24.99)

Playdead's atmospheric puzzle-platformer follow-up to LIMBO. Two to three hours long, no wasted scenes, and one of the more unsettling endings in the genre.

Celeste

$4.99 (75% off, was $19.99)

A precision platformer with genuinely great level design and a story about anxiety that doesn't feel bolted on. Steam Deck Verified.

Human Fall Flat

$5.99 (70% off, was $19.99)

Wobbly physics-puzzle platforming built for playing badly with friends — up to 8 players online, and just as funny solo.

One more genre worth a peek: city-builders

Puzzle games weren't the only underexposed corner of this sale. If you've got any interest in city-building or management sims, this is worth a look too:

Notes

Cities: Skylines

$8.99 (70% off, was $29.99)

Still the reference-point modern city builder, with a huge modding scene on Steam Workshop. Rated Playable on Steam Deck, though the UI is easier to read on a bigger screen.

A note on timing

All five of these discounts are tied to the Steam Summer Sale 2026's storewide event, which closes July 9. Unlike rotating flash sales, there's no benefit to waiting for a better price within the sale window — but there's also no grace period after it ends. If any of these are on your list, today is the day to buy.
