Steam Summer Sale 2025 is in full swing, running from June 26 to July 10, 2025. With thousands of games discounted, it’s easy to get distracted by big-name titles. But amid those blockbuster deals lie plenty of hidden gem deals – fantastic indie and lesser-known games that deserve your attention. This year we’ve sifted through the sale to highlight seven best cheap Steam games that are criminally underrated. Many of these Steam deals under $10 offer immense fun for a bargain price, making them must-buy PC games for anyone looking to expand their library with unique experiences during Steam Summer Sale 2025.
Below, you’ll find our picks for seven hidden gems on sale right now. Each of these games has something special to offer – whether it’s a heartfelt story, innovative gameplay, or just ridiculously good value. Grab them while you can, because the clock is ticking on these deals!
1. The Beekeeper’s Picnic
If you enjoy cozy mystery adventures, The Beekeeper’s Picnic is a delightful point-and-click gem you shouldn’t miss. This Sherlock Holmes adventure explores the post-war friendship of an aging Holmes and Watson in a sleepy Sussex village. It’s been praised as “touching, smart, and stunningly written and acted”, delivering a heartfelt narrative rather than a grand murder mystery. The charming story and well-crafted puzzles make it a standout in its genre. On Steam, it’s 20% off (now $11.19) during the Steam Summer Sale 2025 – a great deal for a highly rated indie adventure (it holds Very Positive reviews on Steam). If you’re looking for a relaxing yet emotionally rich game, The Beekeeper’s Picnic is a hidden treasure worth picking up before the sale ends.
2. Ligo
Puzzle fans seeking a real challenge should check out Ligo, a brain-bending indie puzzler with a unique twist. In this game you control ghostly blob creatures that push blocks – and sometimes multiple blobs simultaneously. The result is a “super-smart, super-difficult puzzle game” with mechanics unlike any other. Ligo starts simply (crushing squids with blocks), but soon you’ll be controlling two or more characters moving in tandem, merging into new shapes to solve complex problems. It’s properly tough stuff, presented very beautifully – perfect for players who love to wrack their brains on clever level design. Ligo is currently 20% off (now $11.99) on Steam store.steampowered.com. With only a few dozen user reviews so far (all positive), this hidden gem hasn’t gotten mainstream attention – making it an ideal pick if you want something fresh and challenging from the Steam Summer Sale 2025’s offerings.
3. Miro
Ever wondered what it’d be like to explore alien worlds through a lo-fi, art-house lens? Miro delivers just that. Made by a solo developer, this experimental exploration game feels like No Man’s Sky crossed with the dreamy ambiance of Proteus. According to Kotaku, Miro is “a lovely example of where indie gaming can be utterly different from big-name games,” embracing “scratchy, experimental weirdness”. In practical terms, that means Miro offers a vast, surreal universe to wander, full of big ideas and unusual sights. It might not have the polish of a AAA title, but its ambition and atmosphere make it a remarkable experience for those willing to try something new. During Steam Summer Sale 2025, Miro is 20% off (about $12). If you’re in the mood for a meditative journey and want to support a true indie hidden gem, Miro should be on your list before the sale is over.
4. Master Key
Fans of classic The Legend of Zelda games will instantly warm up to Master Key. This 1-bit Zelda-like RPG distills the top-down adventure formula to its purest form – you play as an adorable fox venturing through a monochrome world filled with secrets and item-based puzzles. The game is entirely without text dialogue (characters communicate in pictograms), yet it nails the nostalgic Zelda vibe. Critics have called Master Key “a stunning piece of game design” that “tickle[s] all the places A Link to the Past can”. In other words, expect cleverly designed dungeons, tools to collect, and clever exploration that will make any retro adventure fan smile. Even better, Master Key is one of the Steam deals under $10 – it’s 40% off, down to just $7.19 on Steam. For the price of a coffee, you get a lovingly crafted RPG that feels both fresh and nostalgically familiar. This is absolutely a must-buy PC game from the hidden gem pile while the discount lasts.
5. Dawnfolk
Strategy and city-building enthusiasts looking for something different should consider Dawnfolk. This indie city-builder combines old-school simplicity with modern twists. Tired of city sims drowning you in micromanagement? Dawnfolk dials back the complexity with charming tile-based town building reminiscent of classic SimCity, then layers on puzzle-like goals and challenges. According to reviewers, it harkens back to a time when things were “somewhat simpler” in city-builders, yet Dawnfolk isn’t shallow – “teeny events take place within individual tiles” and increasingly complex scenarios keep you engaged. The result is a relaxing yet engaging strategy gem that feels both nostalgic and novel. During Steam Summer Sale 2025, Dawnfolk is 20% off (now $12). It may not have the name recognition of SimCity or Cities: Skylines, but its hidden gem status means you’ll discover a cozy city-builder that many others have overlooked. Build your tiny town before this deal vanishes!
6. Polimines (Complete Pack)
Puzzle game aficionados are truly spoiled this sale, and Polimines might be the best-value gem of them all. Polimines and its sequel Polimines 2 are logic puzzle games that have drawn comparisons to the beloved Hexcells series for their elegance of design. In fact, Kotaku calls Polimines “so perfectly delivered as to be sublime,” an “extra special” puzzle experience. The gameplay involves solving clever numeric logic puzzles (think along the lines of Minesweeper meets Picross, with its own twist), and it’s immensely satisfying for players who love exercising their brain. Both Polimines games are bundled together in the Polimines Complete Pack, which is currently at the best price ever – just $5.61 for both games (58% off). That’s right, for well under $10 you get two brilliant puzzle titles that will keep you busy for hours. This bundle is truly one of the hidden gem deals of Steam Summer Sale 2025. Don’t let its unassuming store page fool you – Polimines is a puzzle powerhouse, and at this price it’s a steal.
7. Wizordum
Rounding out our list is Wizordum, a game that beautifully revives the spirit of 90s fantasy shooters like Hexen and Heretic. Wizordum is an old-school first-person shooter (FPS) with a magical twist – you wield both spells and swords as you battle through its pixelated 3D dungeons. But unlike the frenetic pace of DOOM, this “boomer shooter” emphasizes exploration, secret-finding, and puzzle-solving in its level design. The result is a spectacular FPS that feels refreshingly different from modern shooters: you’ll methodically search for keys, discover hidden rooms brimming with ammo, and take your time to conquer each labyrinthine stage. Critics have deemed Wizordum “bloody marvelous” for how well it captures a classic formula while standing on its own. It’s the priciest title on this list, but still a bargain compared to AAA games – currently 20% off at $16 on Steam. If you have any nostalgia for retro FPS adventures (or just want to see what that genre was about), Wizordum is a hidden gem that will scratch that itch. Grab it now, and get ready to relive the glory days of fantasy FPS gaming.
