For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
It's your first day as a security officer in a mysterious building designed by an unknown architect. Within its vast stairwell, you are tasked with inspecting the floors for reported strange phenomena. Make your way through the building and carefully choose which way to go based on your findings.
If everything is normal, proceed upstairs.
If you notice an anomaly, go downstairs, quickly.
Do not miss too many anomalies.
The Stairwell is a psychological horror game inspired by anomaly loop games such as The Exit 8, with a new vertical dimension of massive scale. There are over 50 anomalies to uncover between all difficulties. You can see how many are left to find after you win a game. Anomalies that you haven't seen will usually appear first.
Compete against the world for the fastest game completion time and see how you rank against your friends. Find your name highlighted on the leaderboard in the color according to your ranking.

Very fun anomaly hunting game. At normal mode, it was just the right amount of spooky, interesting, while keeping me guessing. You can tell love went into the design.
(For disclosure, I helped playtest during early development. Most of my play hours are not represented here since they were on betas.) You're in a museum with an arrangement of strange pieces. It seems to go on up forever into the foggy distance. The base floor is always the same and each successive floor is the same as the previous... or is it? Reportedly this one is inspired by the "Exit 8" game that inspired the "anomaly detection" genre, though I never played it. In this one you need to identify anomalies, which are subtle or obvious changes in the items on the floor. You go upstairs if you think nothing has changed and downstairs if something is "off". If you're right, you get a positive "ding" and the floor number goes up (... even if you went downstairs), else you get an error buzzer and the next floor number can be reset to a lower one in punishment. (And the anomalies change again!) You can take the opportunity to review the floor if you made an error, to double-check to see what you may have missed, though this will not help your score. You win when you get to the top. There are a lot of interesting anomalies to find (the store page screenshots give most of them away, so ignore those if you can). Pros: Overall the anomalies are quite varied, ranging from very obvious to very obscure (in hard mode), and many gave me good chills the first time I recognized them. Some go above and beyond in terms of strangeness. In the various stages and in harder modes, the entire museum is cast into darkness, making it more difficult to make out anomalies. Unreal's Lumen technology is used to great effect here to make things spookier. There is no music but atmospheric fan sounds and your footsteps to accompany you. The game has competitive elements which includes a weekly competition-only map, which rearranges the layout in subtle or dramatic ways, where your task is again to identify what has changed in the upper floor variations, but minimize the time spent in completing the game. These add spice to the gameplay. Cons (minor): Given the gameplay requires recognizing anomalies, it's a shame that one of these involves only audio cues (keep your headphones on, even if it freaks you out), and another few involve things moving around, but without sound effects to accompany them. (It can be a bit frustrating to miss an anomaly that only occurs when you pass it by!) So over time while playing you may learn to obsessively check every nook and cranny, looking in all directions, and traverse the floor back and forth before making a decision. But as you grow to recognize them, some floors can be easily marked as anomalous at a glance, and you can use the convenient chute to go downstairs to mark your choice. My main complaints with this one, at least early on, are with the basic gameplay. Maybe this is what "Exit 8" did, and maybe other players will be fine with it, but I'm not sure I'm on board with a game where your only action is movement. I'd prefer for the gameplay loop to involve clicking on the "wrong thing" directly, to prove you really saw it and didn't just guess, and have the movement be always going upstairs, even if an incorrect choice means the next the floor number is reset. Otherwise, as it is, there is a bit of unnecessary in-game signposting to reduce the confusion about which direction to go, and when and how floor numbers change, which could have been avoided altogether with a more direct interaction. But it doesn't really hurt the gameplay since movement speed is fast enough to get around.
Even if jumpscares don’t scare you, turn off 'Screamers'. It’s REALLY scary
Great game! If you liked The Exit 8, you’ll love this. It follows the same loop-based horror genre perfectly. The graphics are beautiful and the optimization is surprisingly smooth. Highly recommended for fans of the genre.
ほぼ暗闇の難易度があって笑ってしまう。 犬ちゃんかわいい。
This anomaly game is based on the classic Exit 8 principle. The anomalies are rather subtle, which quickly makes you paranoid. However, there are also some larger and more creative ones. There are also 3 difficulty levels and the usability is very good overall. The leaderboards are a nice addition and provide more motivation to do well!

노멀은 내가 원트에 꺨 정도로 이지까까함. 나머지 이상현상 보려고 계속 해보는 중. 근데 이 게임 광대가 주인공임?
