About Flies in a Jar
Flies in a Jar is a puzzle horror game with the simplest job description imaginable: sit at a desk and keep an eye on a jar. You have just been hired by FCL, a secretive organization that studies anomalous entities, and your assignment is room 537, where a sealed jar holds a handful of what the company calls altered creatures. Watch them. That is all.
Of course it is never all. An old computer on your desk fills up with work emails, and not all of them are friendly. One message threatens people close to you unless you set the flies loose. Meanwhile the creatures in the jar stop lying still. They start to move, knock against the glass and test the lid, and you are left weighing orders, threats and your own curiosity against each other.
The Flies in a Jar game turns waiting into the main source of tension. There is very little to do and a great deal to think about, which makes it a sharp choice for anyone who likes slow, cerebral desk job horror with a puzzle or two hidden in the paperwork.
How to Play Flies in a Jar
- Start at your desk and check the computer. Read every email carefully; they explain the job and hint at threats.
- Watch the jar at the center of the room. The creatures inside change their behavior over time.
- Click the jar to see how it reacts, if you dare.
- Use the computer to enter passwords when you find them.
- Turn the lights on and off, and make a phone call if you uncover an emergency contact.
- Search for clues beyond the game itself. Some puzzles point to information on the developer's website.
- Decide whether to open the jar or leave it sealed.
What Makes Flies in a Jar Scary
Flies in a Jar weaponizes boredom. Early on, almost nothing happens, and that stillness makes every small change feel enormous: a twitch inside the glass, a new email arriving, a subject line you do not like. By the time the creatures are clearly trying to get out, you have spent long enough staring at them that you feel responsible for whatever comes next.
The other pressure comes from inside your own head. The game is built around a temptation, and it knows you want to give in. Threats in your inbox push one way, your instructions push the other, and curiosity keeps whispering that one look could not hurt. Contains insects and threatening messages.
Tips for Flies in a Jar
- Read every email in full. Details you skim past are often the ones you need later.
- Keep a note of any passwords, names or numbers that show up.
- Watch the jar regularly. Changes in the creatures signal that the situation is moving on.
- Be ready to look outside the game when you are stuck. A clue may be waiting on the developer's website.
- Take your time. Flies in a Jar punishes impatience more than it rewards speed.

A Chromebook is a good choice, since Flies in a Jar runs in the browser and some puzzles involve typing passwords.

Does Flies in a Jar have jump scares?

Should you open the jar in Flies in a Jar?
That decision is the heart of Flies in a Jar, and we will not spoil it. Your instructions say to watch, a threatening email says to release the flies, and your curiosity says to look. What happens depends on the choice you make, so think it through and see where your decision leads.
