Chaos Meter is a free browser game that measures how well two people actually know each other. One player secretly rates a situation from 0 to 10; the other tries to guess that number. Points come from how close the guess lands.
Why it exists. Most party games ask you to do something—a dare, a confession, a performance. Chaos Meter asks you to predict instead: “How much would this actually bother them?” More often than not, the argument afterward is better than the game itself.
How it works. No account, no download, no game data on a server. Names and scores exist only while you play; the cards you have already played, your settings, and any unlocked packs stay in your browser's own storage. The only personal data that reaches us is the email address attached to a pack purchase, which we keep so we can send your key again if you lose it.
Near or far. The pass-and-play mode is for two people in the same room. The online challenge mode is not: Each of you rates 6 situations and guesses how the other will rate 6 more, and the whole game travels inside one link. It makes Chaos Meter work for long-distance couples and friends who don't live in the same place.
Who it's for. Two people, whether they have known each other for years or just met: couples looking for a free date night at home, friends, family members, roommates, or a first date. The game is for players aged 16 and over: The situations are about the small frictions of real relationships, and they work best when both players answer honestly.
The cards. The base game ships with 144 free situation cards and 40 penalty cards. Optional extra packs add more situations, each with its own theme and its own rating scale.
Not a quiz. A quiz asks you questions about the other person and hands you one score at the end. Chaos Meter asks you to predict a number they picked in secret, and shows the gap after every single card. The gap is the useful part: A miss of 1 is two people rounding the same feeling differently, while a miss of 4 usually means you were picturing a different situation entirely.
What it costs. The 144 situation cards, both penalty packs, and the online challenge mode are free, with no account to create. Optional extra packs are one-time purchases; a pack usually has 36 cards and costs $2.99. The license key that arrives by email can be activated 20 times, so a new phone or a cleared browser does not cost you the pack.
Browser support. Chaos Meter runs in any modern browser (Chrome, Safari, Firefox, Edge) on desktop and mobile, including Instagram's and TikTok's in-app browsers. No install, no account.
Known limitations. Game history and unlocked packs live in your browser's own storage; clearing site data or switching devices resets them, though re-entering your license key restores paid packs. Challenge-mode links encode the whole game and can get long. If one doesn't open from inside a chat app, copy it into a browser directly instead of tapping it in-app.
