Math Fighters: Formula Battle

Math Fighters is a battle game played with math. Pick the right formulas to grow your army and defeat the enemy troops.

Gates carved with formulas like x + 15, x × 3 and x² stand on the battlefield. x is the number of soldiers you have, and marching through a gate changes it by that formula. Tap the gate that gives the most soldiers before time runs out. If time is up, you march through the worst gate. Outnumber the enemy waiting at the end of each wave to win.

It starts with addition and subtraction, and new formulas appear as you go through the stages: multiplication and division, brackets, powers and square roots, fractions and absolute values, exponents and logarithms, factorials, permutations and combinations, and series sums. Even if arithmetic is not your thing, keep trying and you will move on. Solve fast and right for a better rating.

Tough stages can be beaten with items: Slow for more time, Barrier to undo one mistake, Reinforce to start with more soldiers, and Graph to see each formula drawn above the gates. Lose, and a potion lets you pick up partway through.

In the Daily Challenge, take on new questions every day and compete with players around the world.
