The Appeal of Steam Review Guesser: Free, Addictive Fun and Its Link to GeoGuessr

Steam Review Guesser is a quiz game where you guess the number of reviews for a random game listed on the Steam platform. The number of reviews on Steam is a very direct indicator of how successful a game was in the market.
The Origin Story: From Chrome Extension to Browser Hit
This game originated as “Jonas Review Guesser,” a Google Chrome extension developed by indie game developer Jonas Tyroller. Tyroller himself confessed to being hooked, saying he “played it for four hours yesterday and got addicted”.
Developer Fiddler later released a free, browser-based version to eliminate the “slightly high hurdle” of installing the GitHub extension. Fiddler is believed to be an individual developer currently working on the horror game Anatomy of Dread.
The Concept: GeoGuessr for Game Developers (and Enthusiasts)

This game has been described as “GeoGuessr for game developers”.
GeoGuessr is a geographic exploration and location-guessing game where players deduce a location based on hints like scenery, terrain, and signs seen through Google Street View. Similarly, Steam Review Guesser tests observation and deduction. Players rely solely on information displayed on the Steam store page—the trailer, screenshots, description, release date, and developer name—to determine how much market attention the game garnered.

How to Play Steam Review Guesser: Is It Free and Safe?
You can start playing Steam Review Guesser simply by accessing the public page (https://steamreviewguesser.com/) from a PC, iOS, or Android browser.
Basic Settings for Free and Safe Play
The game is offered for free and does not require special account creation or login.

While the game language is English only, operation is straightforward—you just choose the correct answer from the 5 review count options.
The “Preferences” settings (top right of the screen) allow you to toggle the display of the publisher name and filter out age-restricted games (Adult Only/NSFW games). While the risk of encountering age-restricted content is low if you are not logged into Steam, it is recommended to filter appropriately if you wish to completely avoid the display of such content.
Gameplay Rules and the Scoring System
When you start, a UI similar to the Steam store page appears, but the review section displays five buttons with numbers.

Your task is to guess the All Reviews count (all languages).
100 points are awarded for a perfect guess, and 50 points are awarded for choosing the adjacent option. Any other choice results in 0 points. A single game session consists of 5 rounds, allowing for a maximum total score of 500 points, and the total lifetime score is also tracked.

After answering, a “Steam” button appears, allowing you to access the actual game’s store page to verify the review count.
Two Game Modes: Raw and Balanced

The game offers two modes that determine the range of games presented:
- Raw: Presents a completely random selection of games from Steam.
- Balanced: Filters out games with extremely low review counts (e.g., games with zero reviews).
Since about 50% of games released on Steam have fewer than 10 reviews, and many games exist that developers might call “trash games,” choosing Raw mode exposes players more strongly to the harsh reality of Steam. Balanced mode is more suitable if you want a purer quiz focused on predicting game success.
My Experience Playing Steam Review Guesser: The Good and the Hard Truth

I played Steam Review Guesser myself. Like GeoGuessr, it is beneficial because market knowledge is gained while having fun. However, I also felt the addictive quality that makes you lose track of time, and the aspect of being confronted with the harsh realities of game development.
The Upside: Addictiveness and Discovery
1. Easy to Dive Right In
There’s no need to learn complex controls; you start immediately just by accessing the website. It’s easy to enjoy during breaks or short free moments.
2. Endless Addiction
Though simply about guessing review counts, the game is “surprisingly captivating”. Because its nature is seemingly “endless,” I “kept playing for quite a long time”. The developer himself noted his addiction, playing for four hours in one day. Even when incorrect, the desire to succeed on the next round drives endless exploration.
3. Discovering Unknown Gems
I encountered many unknown games during my playtime. This is a definite benefit, leading to the discovery of new titles. Just as GeoGuessr reveals local scenery you wouldn’t normally see, Steam Review Guesser can be a chance to find niche games or hidden gems you wouldn’t typically pay attention to.
The Difficulty and Key Takeaways: What Determines Success?
I quickly realized that accurately predicting the review count is extremely difficult. Encountering games with “surprisingly more or fewer reviews” than expected made me feel that “my own perception might have been biased”.
By playing repeatedly, I started noticing factors readable from the store page that influence a game’s success:
- Capsule Art Quality: The quality of the small thumbnail (capsule art) and the execution of the screenshots tend to significantly impact success. Poor art generally correlates with lower review counts.
- Trailer Importance: Games where the trailer starts immediately with action or gameplay tend to grab player interest and receive higher ratings. Conversely, the harsh reality is that games with laggy trailer footage or visible debugging displays often see fewer reviews.
- Pricing: Lower-priced games (especially those around a few dollars) tend to sell very well, whereas overly high pricing can hinder review growth.
- The Publisher Factor: Games with a publisher tend not to have zero or near-zero reviews, as that would be “embarrassing for the publisher”.
However, it is extremely difficult to spot “positive outliers” (unexpectedly successful games) because the brain gets used to predicting low-review games.
The Emotional Pitfall: The Harsh Side of the Market

This game is sometimes described as “highly interesting, yet profoundly painful”.
When encountering a game that looks incredibly well-made yet has an extremely low review count, it’s a moment of “heartbreak,” confronting the reality that the developer’s “effort has not been rewarded”. This happens, for example, when games with superb graphics suffer from low review counts due to market saturation or unmet needs (like the difficulty of platformers succeeding in the modern era).
Just as the GeoGuessr demo was called a “dangerous game you end up buying”, Steam Review Guesser also possesses the “danger” of being a time sink, as players forget the time and engage in endless game exploration.
Sharpen Your Market Insight with Steam Review Guesser
Steam Review Guesser offers a unique experience where you deduce a game’s success from the limited information on a Steam store page.
Beyond the fun of a free quiz game, it has an educational side, providing a glimpse into the reality of “what is valued and what gets buried” in the Steam market. Just as playing GeoGuessr repeatedly builds knowledge of geography worldwide, playing this game naturally helps you learn market trends and tips for selling successfully.
Playing in Raw mode, in particular, allows you to witness the “harsh reality” of the diverse range of games on Steam.
Why not try Steam Review Guesser? You can hone your market insight, enjoy the pure thrill of guessing review counts, and experience the new discovery of encountering many unknown games you wouldn’t usually see.
