Happy Number

Welcome to Happy Number, the addictive number puzzle game that makes math thrilling.

In mathematics, a happy number is one that eventually reaches 1 when you repeatedly replace it with the sum of the squares of its digits. Your mission is to identify and tap the happy numbers as they rain down your screen while carefully avoiding the sad ones.

The rules are simple: tap golden happy numbers to score points and build combos, but stay away from the red sad numbers or you will lose a life. Miss a happy number and it costs you too. The longer you survive, the faster and harder it gets.
