SolveOn

SolveOn is where you challenge yourself and grow as a problem solver. Solve original math problems, earn a Skill Rating from Ranked Runs, and climb your tier, the all-time board, and the Weekly Contest. Competition and practice are free for everyone. • 2,800 original problems on one ladder from Grade 9 to university: number sense and algebra, linear relations, quadratics and trigonometry, functions, sequences and finance, advanced functions and calculus, contest problems in the style of high school math competitions, and first- and second-year university topics such as integration techniques, series, matrices, partial derivatives, eigenvalues, differential equations and probability. • Pick your level once and everything follows: where your placement run starts, what mixed practice serves, and Easy / Medium / Hard labels that mean something at your level. Every level stays open. • A scratch pad on every question — work it out on screen with a finger or Apple Pencil. • Ranked Runs: five questions matched to your rating, starting with a placement run that finds your level. Your Skill Rating is a statistical estimate of demonstrated ability — it can go up or down, and only Ranked Runs move it. • A Weekly Contest shared by every player, scored on accuracy and speed, and leaderboards for your rating tier and all time. • Practice by level, topic or difficulty, as much as you like. Type exact answers — fractions, π, square roots — on a keypad built for math. • XP and a small set of achievements that mark real progress. No streak pressure, no lives. • No account needed. You get a random username; Sign in with Apple is optional and only keeps your progress across devices. No ads, no tracking.
