Millennium Problems
7 Unsolved Math Mysteries
Free · Designed for iPad. Not verified for macOS.
The 7 greatest unsolved problems in mathematics through interactive 3D visuals and 700+ quiz questions — adapted for every level from Grade 6 to Graduate.
Can you solve a problem worth $1,000,000?
The Clay Mathematics Institute has offered a million-dollar prize for each of seven unsolved mathematical problems — and nobody has claimed them yet. Millennium Problems brings these mysteries to life for everyone, from curious 11-year-olds to doctoral researchers.
SEVEN LEGENDARY PROBLEMS
• P vs NP — Is finding as hard as checking?
• Riemann Hypothesis — Where do prime numbers hide?
• Yang-Mills & Mass Gap — Why do particles have mass?
• Navier-Stokes — Can we predict turbulent fluids?
• Hodge Conjecture — What shapes are built from algebra?
• Birch & Swinnerton-Dyer — How many solutions does an equation have?
• Poincaré Conjecture — The shape of the universe (SOLVED!)
EVERY SKILL LEVEL
Choose your grade — from Grade 6 to Graduate — and the content adapts instantly. The same problem is explained with simple analogies for a middle schooler and rigorous proofs for a PhD student.
INTERACTIVE 3D VISUALISATIONS
Every problem comes with a real-time Three.js visualisation. Watch elliptic curves rotate, Riemann zeros appear on the critical line, and fluid particle fields swirl — all rendered natively on your device.
BUILT-IN QUIZZES
Test your understanding with 5 questions per problem per grade level. Earn XP, track your streak, and collect badges as you explore.
WORKS OFFLINE
No account. No subscription. No ads. Everything runs locally on your device.
OPTIONAL BIOMETRIC LOCK
Protect your progress with Face ID, Touch ID, or fingerprint — entirely optional.
Whether you're a student looking for a challenge, a teacher seeking engaging material, or a mathematician revisiting the classics, Millennium Problems meets you where you are.
