You stand beside an indoor swimming pool and press GREEN because nothing seems off. The water resets, the same room returns, and you realize you just failed a test you did not know had started. That small moment of doubt is what POOL LOOP is built on.
| Genre | Observation horror, adventure |
| Perspective | First-person |
| Mode | Single-player |
| Platform | PC |
| Core input | RED and GREEN buttons |
| Setting | An endlessly looping indoor swimming pool |
The setup is stripped down to one decision. You are locked inside a swimming pool hall that repeats itself, and every pass gives you a chance to judge whether something has changed. If the room feels wrong, you press the RED button. If it feels normal, you press the GREEN button. There is no inventory, no combat, and no map, so attention is the only resource this game gives you.
Most beginners treat the first few loops as a warm-up and stop looking carefully. That habit is exactly what the pool punishes, because nothing announces the moment an anomaly appears.
Players who arrive from Exit 8-style walking games usually settle in fast, since memorizing a space and comparing it to the next pass carries over directly. Here the memory work is anchored to a single location instead of a corridor, so you study the water, the lighting, and the shape of the room until a wrong detail starts to itch. Community talk about the genre keeps returning to the word anomaly, and the pool is a clean example of why.
The two buttons look symmetrical, but they carry different kinds of risk. GREEN is the answer you give when the room matches the last pass, which means you are betting on your memory. RED is the answer you give when something feels wrong, which means you are betting on one detail you may have imagined. Because a wrong call keeps the loop going, both mistakes cost the same, and that equal penalty is what makes hesitation feel so heavy.
Overthinking causes more failed loops than missing things does. A player who presses RED on a hunch and a player who presses GREEN out of tiredness end up in the same place, back at the start of the pool.
Not everyone enjoys this rhythm. Because a wrong call simply sends you around again, some players find the repetition tiring when an anomaly is subtle, while others argue the grind is the point, since the horror comes from doubting a room you have already seen. Store reviews lean positive without being unanimous, which fits a game that demands patience and rewards it unevenly.
The loop does not end at the surface. Once you dive beneath the water, the pool stops being a place you only look at and becomes a place you explore, and that is where the game widens past a pure spot-the-difference routine. Players tag it with multiple endings, so completionists will want to run more than one route before calling it done.
A few habits help before your first dive:
The tone is quiet, empty, and slightly wrong, which suits fans of liminal space horror who prefer dread to chases. Wearing headphones and playing in one sitting works better than short sessions, because the pool is easier to judge when the last pass is still fresh in your head.
The RED button is your answer when you believe the pool contains an anomaly, and the GREEN button is your answer when everything looks normal. A correct call moves you toward the way out of the loop, while a wrong call keeps the loop going. Every decision in the game runs through these two buttons.
Compare each pass against the previous one, starting with the water and the lighting and then moving to smaller details. Anomalies in this kind of game are often subtle, so a fixed viewing spot helps more than wandering around. If you cannot name what changed, the safer press is usually GREEN.
Players tag it as psychological horror with jump scares, but most of the tension comes from observation and doubt rather than from being chased. The dive beneath the surface raises the unease, so expect a slow, uncomfortable mood with occasional sharp moments rather than constant action.
POOL LOOP rewards the player who treats a calm room with suspicion. Every press of the RED button or the GREEN button is a small bet on your own memory, and the dive beneath the surface raises what that bet is worth. If you enjoy the quiet dread of liminal spaces, the pool is worth a few loops.
