ANGRYMATH
1 second. No excuses.
A one-second true-or-false math reaction game with solo runs, same-device battles, and live cross-platform leaderboards.
A statement flashes up. The timer drains. Decide whether it's right before your streak disappears.
How to play
Brutally simple.
Impossibly hard.
A math statement flashes on screen and the timer starts draining immediately. You have one second to verify it, not work it out slowly. Every correct answer extends your streak. One mistake, or one hesitation, ends the run.
17 × 3 > 48
Read the problem
A math statement appears with =, >, or <. Decide whether the whole thing is right.
Beat the clock
The timer bar drains in exactly 1 second. Think fast — hesitation is as fatal as a wrong answer.
True or False
Tap your answer. Correct? Next problem. Wrong? Game over. No second chances. No mercy.
Features
Everything you need.
Nothing you don't.
Live Cross-Platform Ranks
Five public leaderboards, one for each difficulty. New personal bests are submitted automatically so you can measure yourself against everyone else.
Per-Difficulty Records
High scores are tracked separately for Easy, Normal, Hard, Super Hard, and Mix so each mode has its own chase.
One-Second Pressure
The timer bar drains in a single second and changes colour as time disappears. You feel the danger before the buzzer proves it.
Feedback That Lands
Countdown ticks, score chimes, haptics, and a clean fail state make every right answer and every collapse feel immediate.
One-Phone Showdowns
Same-device local battles turn one phone into a face-off machine, with each player attacking the same timer from opposite ends of the screen.
Focus-First Design
Dark purple backgrounds, high-contrast maths, and almost no chrome keep attention on the statement, the timer, and the next tap.
Play modes
Two ways to play.
Solo grind or same-device battle. Same core rule, two very different kinds of pressure.
Single Player
Pick a difficulty, survive as long as you can, and push your personal best higher. Every new record can move you up the live global leaderboard for that tier.
Same Device Face-Off
Hand one phone to a friend. The screen splits in two, with Player 2 rotated 180 degrees so both of you can battle from opposite ends of the same device.
Difficulty
Five levels.
One that will break you.
Pure recall
Single-digit sums built for beginners, younger players, and anyone warming up.

The Science
Not just a game.
Fast arithmetic training.
Fast Recall, Not Slow Calculation
The one-second limit is tuned for System 1 thinking: pattern recognition, memorised facts, and instant magnitude checks instead of step-by-step working.
Arithmetic Fluency Matters
Arithmetic fluency is a strong predictor of later maths success. Angry Math compresses that repetition into short, high-pressure bursts that reward automaticity instead of guesswork.
Recognition Beats Generation
True-or-false verification is faster than generating an answer from scratch, which is why the game can show harder-looking numbers while staying realistic inside a one-second window.
Competition Extends Practice
Leaderboards and head-to-head play create the social pressure that keeps people running one more round, which is exactly what timed drills usually fail to do.
No nonsense
Just the game.
No distractions, no tracking stack, no locked core loop. If you join the leaderboard, only the minimum anonymous ranking data leaves your device.
