How to play ONE LIE

Each case has one unique answer in the range. The false clue is marked red with a THE LIE badge after the case ends; every clue also shows its explanation or number confirmation. Your result names your guess and confirms the answer.

A correct answer starts at 1,000 points and loses one point for every full second. A wrong guess uses your attempt and scores zero. Reloading after you start does not pause or reset the timer.

Daily gives one server-stored attempt per day, including for guests. Unlimited remains browser-local and loads fresh cases from the API. Link an account to carry eligible guest history with you.

The three arithmetic clues come from three different categories: basic numbers, digits, mathematical properties, arithmetic transformations, and quirky number facts. Two categories are randomly left out each case. Repeated digit addition, binary, Fibonacci, triangular-number, factor-count, square-digit-sum, and combined divisibility clues are temporarily excluded from new cases. Daily and Unlimited use the same rules.
