How to Play QuickCalc
Choose the correct answer, or use keys 1–4. Consecutive correct answers build a combo for more points. Classic and Daily give you 3 hearts and a timer for each question. The daily course changes at midnight UTC and can be replayed for practice. Timed modes subtract 3 seconds for each wrong answer. A 30-second duel uses the same question sequence and answer positions for both friends, with no hints or extra time. Share your result to send that exact course to a friend. Challenge scores are self-reported and are not a verified leaderboard.

What is Operator Roulette?
From question 11, some questions hide one operator, such as 7 ? 3 = 21. Choose × to solve it. Correct operator answers earn double points. Outside duels, a hint can narrow the choices to two.
How are answer choices made?
Numeric choices mix the correct value with nearby and more distant errors, then shuffle their positions. Duel friends receive the same choices in the same positions.
