Lightning Math Battle

Lightning Math Battle is a free math-quiz action game that runs in this browser tab. Press Play, pick one of eight practice modes, choose Easy, Medium, Hard, or Boss, then tap or click one of the four answer buttons at the bottom of the frame - every correct answer charges a lightning strike against the monsters on screen.

The control walkthrough in full

Eight practice modes at four difficulty tiers

The modes cover addition and subtraction, times tables, tens and ones, number patterns, how many, number bonds, money, and the number line, and each one runs at all four difficulty tiers from Easy up to Boss. The answer grid is sized for touch on a phone, and a desktop mouse click does exactly the same thing, so a run works the same way on either device. A mute button sits in the top-right corner of the frame.

Progress stays in this browser

There is no multiplayer and no cloud save, so a player's best-star ratings live only in this browser under a namespaced key and will not follow them to a different device. The title overlay also opens a Research panel and a Progress panel from in-game links, so a player can check which practice modes need more work without leaving the page.

What loads when you press Play

Pressing Play injects about 1.29 MB of game into an iframe on this page: a Canvas 2D playfield with a vendored three.js lightning overlay, and zero CDN calls once it is running. Adapted from pasuay/thunder-math (MIT).

How it differs from the other games here

This is an answer-and-strike action game rather than a pure logic puzzle like Thirteen Step Escape or a first-person shooter like Voxel FPS Arena - here the arithmetic is what powers the combat layer. You can browse the rest of the browser games too.
