Math Vale
The RPG where rules are math
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.

Math Vale is now free to download. Starter Village, Number Kingdom, Fraction Isles and Algebra Kingdom are free for ever, with no limit and no advertising.
