Nerdy Math

Read full description

Nerdy turns math practice into something you actually want to open — and now it trains the rest of your brain too. Work through 502 cards across 43 topics, from counting and times tables to fractions, exponents, probability, trigonometry and logarithms. Every card is played as one of 9 quick mini-games, so practice never feels like a worksheet. When you want a different kind of workout, Brain Lab is one tab away. WHAT'S INSIDE • 502 cards across 43 topics. Questions are generated fresh each time, so there is no answer key to memorise. • 9 mini-games — drag and drop, true or false, multiple choice, timed tests, balloon popping, rocket launches, star catching and maze runs. • 112 logic puzzles across 6 chapters and 31 puzzle types: magic squares, KenKen, nonograms, matchstick puzzles, cryptarithms, cube nets, mirror puzzles and more. • Live Arena — an always-on global round you can join at any moment, with live standings and a recap of what you missed. • Private races — invite up to 8 friends with a room code or QR code. Play a single round, or a best-of-3 or best-of-5 series. • Three-star scoring. Perfect and quick earns three stars; two mistakes end the card. BRAIN LAB • 12 short games across six skills: attention, speed, memory, flexibility, focus and math. Color Clash, Number Hunt, Memory Grid, Path Recall, Rule Switch, Target Sum and more. • Every game adapts over 10 levels, and scoring rewards careful play — fast random tapping does not win. • Today's workout: three games from different skills, about five minutes, always free. • A brain score from 0 to 1000 and six ranks, from Spark to Genius. • Brain Report: your skill profile, a 14-day trend, a speed-and-accuracy reading and a four-week training calendar. • Journey: chapters of stations that open new games as you keep training. BUILT FOR THE RIGHT LEVEL Choose an age band — 5-7, 8-10, 11-13 or 14+ — and Nerdy shows only the topics that fit. Kids mode keeps all 9 mini-games. Teen mode drops the arcade ones for straight practice. PLAYS ANYWHERE The card game, every riddle and Brain Lab work offline. Sign in when you want leaderboards, achievements and multiplayer; your progress syncs in the background across your devices. ALSO INCLUDED • Achievements and leaderboards through Game Center • Streak reminders that stay quiet once you have played for the day • 8 themes with animated backgrounds, plus light and dark modes • Screen reader support, larger text layouts and colours that stay readable in every theme • Available in English, Turkish, German, Spanish, French and Chinese Nerdy Premium unlocks every card, all 112 riddle levels and the full theme set, plus free play across every Brain Lab game, per-skill trends and rating history.
