Is your brain feeling a little rusty lately?
Introducing "Four 4s," the historic math puzzle born in Great Britain in 1881, now available as an iPhone app!
The rules are very simple. In "Four 4s," you just arrange four "4"s and operator panels like +, -, ×, and ÷ to create an equation.
Your challenge is to make the answer equal every number from 0 to 100.
It looks easy, but it's deceptively deep. Can you use your full insight and mathematical mind to complete all the numbers?
It's as easy as moving the panels with your finger, like "44 × (4 - 4) = 0"!
But... can you make a number like 73?
Loosen up your rigid thinking and have fun training your calculation skills and creativity.
By the time you clear all the puzzles, your math brain will be more powerful than ever!
・ Simple Controls: Just arrange the panels as if you were playing with blocks. It's that easy!
・ Endless Challenges: Once you've conquered the "Four Fours," take on new challenges with "Four 1s" or "Four 3s"!
Achieve great results to unlock a mode where you can play with any numbers you like.
・ Completely Free: The game is supported by ads, so you can enjoy the entire experience for free.
Turn your spare moments into the ultimate brain-training time. Download now!
