Function Battle

Maths artillery. Real duels.

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Write the function, fire the shot. Turn-based artillery where you aim with real maths: campaign, pass & play on one phone, and online rooms with friends. Aim with maths. 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 maths 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 MATHS 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 revising, 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. MAKE IT YOURS Colours, shapes, faces, hats, glasses, shot trails, body effects and emotes. Earn Sparks by winning, open chests (the odds are always shown) and spin the prize wheel. Watching an ad is always your choice. ALSO INSIDE • Save and rewatch replays of your best shots. • Play in 11 languages: English, Español, Português, Deutsch, Français, Italiano, Türkçe, हिन्दी, 日本語, 한국어, 繁體中文. • Accessibility: larger text, reduced motion, and separate sound, music and vibration settings. • Safer online play: quick reactions, mute, block and report, and clear community rules. Typed chat is off for players under 13. • Free to play. Accounts are optional: play as a guest straight away. Ads are voluntary rewarded videos only. They never interrupt a match.
