What if the world's top genius was living among us, but no one even knew? Could it be one of your friends? Could it be you? Let's find out once and for all in a worldwide competition of Math Stan! When the timer starts, you get 30 seconds to answer as many questions as possible. Key in the correct answer, and you gain a valuable point and extra time. But be careful, my friend. If the incorrect answer is tapped, you will receive the dreaded ONE POINT DEDUCTION! Can you handle this pressure? Some say the timer is too fast. Others say the competition is too intense. Most say the frantic music isn't really conducive to mathematical concentration. MATH STAN! GAME MODE • The longer you go, the harder it gets — easy sums warm you up, then bigger sums and subtraction, then multiplication and division, and finally a bank of "extreme" brain-benders (squares, cubes, decimals, and monster-sized sums). • Every game you finish permanently earns you a sliver of extra starting time. Grind daily to build your advantage. • Claim your spot on the Worldwide Leaderboard, ranked by Highest Scores and Longest Streaks! PRACTICE MODE • No clock. No penalties. Just you and the numbers. • Star the problems you've learned, shuffle the deck, and filter by level. AND MORE • Game stats to track your progress over time. • Lots of customizable settings: Light Mode / Dark Mode, Fonts, Sensei Mood, Haptic Feedback, and more. • Optional: Sign in to save progress and sync across devices. Made with love. Math Stan has zero ads and will always be 100% free. Enjoy!

Dans cette histoire, les joueurs incarnent Sonam et sont invités à faire preuve d’agilité et de persévérance jusqu’à atteindre le mythique sommet. L’aventure est émaillée d’informations sur ce point culminant à 8849 mètres qui a fait couler tant d’encre et qui continue de nourrir les passions de milliers d’alpinistes, chevronnés ou pas, à travers le monde. Dans son journal de bord, Sonam note soigneusement ses impressions, ses craintes et ses joies. Des conditions météos changeantes aux décors évoluant selon l’altitude et l’heure dans la journée, « Everest, mon défi » se joue comme un parcours initiatique dans les fantastiques paysages de la chaîne de l’Himalaya.
