Formula Frenzy: Math Puzzle
Daily Brain Training Game
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Three numbers. Four operations. Ten targets. One clock.
Formula Frenzy is a quick maths puzzle that gives you a small set of numbers and challenges you to build a working formula for every target from 1 to 10, in order, before the timer runs out. Use +, −, ×, ÷ and parentheses — each number can only be used once per formula, but you can reuse an operator as many times as you like.
It sounds simple. It isn't always.
HOW TO PLAY
Press Start and your numbers are revealed
Type a formula that equals the current target
Solve it to unlock the next target
Clear all ten before the clock hits zero
TWO WAYS TO PLAY
Easy — 3 numbers, targets 1–10, completely free
Hard — 4 numbers, targets 1–20, for players who want a real challenge. Try it free for 3 rounds, then unlock it with a £2.99/year subscription. Cancel anytime.
CHOOSE YOUR PACE
Every difficulty now comes in two speeds:
Standard — the original pace: 2 minutes on Easy, 4 minutes on Hard
Blitz — for when you want it faster and harder: 1 minute on Easy, 3 minutes on Hard
Switch between them any time — your choice only applies to your next round, so you're never caught out mid-solve.
EVERY ROUND IS SOLVABLE
Before your numbers are even revealed, Formula Frenzy checks that every single target is actually achievable with them — no impossible rounds, no dead ends.
STUCK? SHOW THE ANSWER
If you're well and truly stuck, you can reveal a working formula for your current target — though doing so ends that round, so use it wisely.
Quick to learn, quick to play, and easy to come back to for a few rounds of mental math and brain training whenever you've got a spare couple of minutes.
