Math Vale is a role-playing game where the world runs on mathematics. Every kingdom is a branch of it, every Keeper guarding a gate is a set of real problems, and the only way forward is to understand the idea — there is nothing to grind and nothing to rush. • 141 skills across eleven kingdoms, from counting and fractions to trigonometry, calculus and linear algebra • Lessons that explain, hints that nudge without giving the answer away, and a Journal that keeps every mistake so you can fix it later • Problems that adapt to what you know, and reviews that come back when a skill starts to fade • A homestead to build, quests, dragons and hidden caves of competition problems • Play alongside classmates and family, spar with a friend, or defend a castle together Four kingdoms are free for ever — counting, number sense, fractions and algebra — with no limit on how much you play. The other seven, geometry through calculus and linear algebra, open with a subscription or a one-off unlock, and a free fortnight begins the first time you reach them. Nothing inside the game is ever for sale: no coins, no lives, no hints. Built for children, so it asks for very little: a username, a display name and a password — no email, no phone number, no date of birth. No adverts, no analytics, no tracking.
