Function Battle

Write the function, fire the shot. Turn-based artillery where you aim with real math: campaign, pass & play on one phone, and online rooms with friends.

Aim with math. Write a function, fire the graph and knock out the other squad in this turn-based artillery game.

Function Battle turns graphs into weapons. Type 0.25*x, sin(x) or x^2/40 on the math keypad, press FIRE and watch your curve fly across the battlefield. Bend it over walls, around pillars and onto the enemy. Miss, and you see exactly where your function went, so the next shot is better.

PLAY YOUR WAY • Versus the computer: four difficulty levels, from friendly to ruthless. Works offline. • Campaign and practice lab: learn each kind of function one shot at a time, and see your curve before you fire. • Daily Challenge: a fresh match every day, with bonus Sparks for winning. • Pass & Play: two players on one phone, no account needed. • Online multiplayer: Quick Match, public rooms for up to 10 players (1v1, 2v2, 5v5 teams or free-for-all) and private rooms with a six-letter code for friends and classmates.

A MATH GAME THAT DOESN'T FEEL LIKE HOMEWORK Linear, quadratic, trigonometric, exponential and logarithmic functions, fractions, powers, square roots and absolute values are all ammunition. It's graphing practice, algebra and trigonometry with a bang: great for students studying for tests, teachers looking for a classroom game and anyone who loves a puzzle.

FAIR PLAY Skill decides every match. Nothing you earn or buy changes how a shot flies: no power-ups for sale, no energy bars, no forced ads.
