How QuickMath works
One game engine connects the Daily Sprint, adaptive Practice, searchable game pages, and private friend challenges.
1. Start with one tap
The Daily Sprint begins immediately—no account, countdown, tutorial, or installation. Everyone playing the same calendar date receives the same deterministic sequence. Your browser timezone selects the date, with UTC as a safe fallback.
2. Solve what you can
Type with a physical keyboard or the large on-screen keypad. Correct answers add one point. Wrong and skipped answers reveal the result briefly and move on. There are no lives, penalties, multipliers, or hidden scoring rules.
3. See useful progress
Results begin with your personal best, accuracy, weekly consistency, and nearby verified players. Percentiles appear only when at least 200 verified official attempts exist, and never claim to measure intelligence.
Practice and challenges
Practice offers six modes, adaptive or fixed difficulty, and timed or untimed sessions. A friend challenge preserves the exact seed, ruleset, mode, difficulty, and format so both people face the same questions.
