Function BattleMaths artillery · iPhone, iPad & Android
Aim with maths.
Write a function, fire the graph and knock out the other squad. Turn-based battles against the computer, a friend on the same phone, or up to ten players online.
Coming to the App Store and Google Play in October 2026.
f(x) = 14·sin(πx/130) − 22.2·(x/93.3)60 + 11.4/(94.3 − x)
one shot, three hitsHow a shot works
Every shot is a graph. The battlefield is a coordinate grid, and your function decides the path.
Type a function
Use the maths keypad:
0.25*x,sin(x),x^2/40, fractions, powers and roots.Fire the graph
Your curve flies across the grid from your character. Bend it over walls, around pillars and onto the enemy.
Learn from the miss
You see exactly where your function went, so the next shot is better. Skill decides every match.
