About Number Sum Game
Number Sum is a 50-stage addition logic puzzle game which was inspired by Sudoku and Nonogram games. Use the numbers along the edges to circle the number tiles which are active and erase the tiles which are not part of the final solution. A button set near the bottom allows you to switch between erasing and circling numbers. To the right of the circle button is a hints button. As you advance through the game some stages have colorful areas which also indicate the sum of the number tiles in that area. Correctly satisfy all the addition equations for each row, column, and colored area to beat each stage and advance to the next level. You can guess wrong on a few placements on each stage, though if you run out of health (as indicated by heart containers along the top) you have to play the stage over again. This is a JavaScript web application which uses cross-platform mobile-friendly HTML. All modern web browsers like Microsoft Edge, Apple Safari, Google Chrome, Mozilla Firefox and Opera should support it. This game works on just about any type of computing device including Microsoft Windows desktop computers, Apple OSX Mac computers, iOS powered tablets and phones like the iPad and iPhone, laptops like the Google Chromebook, and the many types of mobile phones from manufacturers like Samsung which are powered by Google Android.
