Math just got a whole lot more epic. Algebros is a turn-based RPG where your weapon is algebra and your enemies are equations. Explore 5 handcrafted zones, battle increasingly tough math bosses, and level up your character — all by actually solving math problems. No grinding for clicks. No passive tap-to-win. Every fight is won or lost by how fast and accurately you can solve an equation. BATTLE WITH MATH Each attack requires you to answer a math question correctly. Get it right and you deal damage. Hesitate or miss and the enemy gets the edge. Speed bonuses reward sharp thinking and punish hesitation. 5 ZONES TO CONQUER • Starter Meadow — Master the basics with Petunia as your guide • Fraction Falls — Navigate ratios and fractions with Splashdown • Multiply Mines — Scale up with Digger McGee underground • Variable Village — Solve for x alongside Mayor X • Equation Empire — Face General Equals and the hardest linear equations in the land TRAIN, SHOP, LEVEL UP Visit the Dojo in each zone to drill the math before you fight it. Stock up at the Shop on Tonics and gear between battles. Earn XP, level up, and unlock powerful new battle techniques. EPIC BOSS FIGHTS Every zone ends with a boss battle — from The Calculator to the final showdown against The Equation. No running. No cheating. Just math. BUILT FOR REAL LEARNING Algebros covers 4th grade math through early algebra — addition, subtraction, multiplication, division, fractions, variables, and linear equations — but you won't feel like you're studying. You'll be too busy trying not to get destroyed. Perfect for students who hate worksheets, parents who want something that actually works, and anyone who's ever wanted to punch a fraction in the face. Download free. Start your adventure. Become an Algebro.
