Last updated: 2026-10-23
These terms describe use of Plain Game at plaingame.fun, operated by chaozicoder. Contact support@plaingame.fun with questions. By using this website, you agree to these terms. If you do not agree, stop using it.
The game
Plain Game is a free browser estimation game for casual entertainment. It includes a daily challenge, practice and untimed Discovery. You do not need an account or purchase to play. Available modes and rules are explained in How to Play, Game Modes and Scoring.
This is an independent implementation, not a service operated by or affiliated with playplain.app. The original Plain website is playplain.app.
Progress and score comparisons
Game progress is saved in your browser. You are responsible for exporting a backup if you want to keep it when clearing site data or changing devices. We cannot promise recovery of lost local progress. Website accounts do not provide automatic game-progress synchronization.
Shared scores are self-reported and intended for friendly comparison. The game does not provide a verified global leaderboard or a prize competition. Data or rule updates can change generated routes; compare results only when the route, mode and version are compatible.
Reference information
Game values are frozen references, some approximate. A displayed answer is the value used for that game version, not a guarantee of the latest measurement or a complete factual audit. Units, geographic definitions, editions and source dates can differ. Read Sources & Limitations, and consult an appropriate original source before relying on a value outside casual play.
Responsible use
Use the website without interfering with other visitors or accessing information you are not entitled to access. Do not attempt unauthorized access, distribute malware, disrupt the service or use its communication features to harass others. If you use an optional account, keep its credentials private and report suspected unauthorized access to support.
You may share your own result images, game links and challenge codes for their intended purpose. Sharing does not give you ownership of the website's artwork, music or other original material. Third-party names, facts and linked materials remain subject to their respective rights; a reference link does not imply endorsement.
Availability and changes
Features, question data and rules may be corrected or changed. The service may be interrupted for maintenance or technical reasons. We do not promise uninterrupted availability, preservation of every past generated route or any particular game score or learning outcome.
Access may be restricted where reasonably needed to address misuse or protect the service. Material changes to these terms will be recorded by updating this page's date. Nothing here is intended to remove rights that applicable law does not permit to be waived.
Privacy and contact
The Privacy Policy explains local storage, website accounts, cookie choices and support messages. For a data correction, include the category, answer, displayed value and a supporting source. For other questions, email support@plaingame.fun.
