The guide

Overview

Dive into Number Sums, a logic puzzle game that will put your number-crunching skills to the test. Strategically select grid cells to achieve precise target sums across rows and columns. With 5000 levels, this addictive challenge promises endless brain-bending fun. Will you reign as the ultimate puzzle master?

Children in the early school years want to feel competent, and junior games are built to let them. The controls are simple but real: steer a character, time a jump, pick the right answer. The stages are short and the mistakes are forgiving. A session might run through five or six stages with a star rating on each, and a child can see themselves improving.
