Ready for one of the most difficult thinking games of your life? Then start playing Sum Master now! In this game, you solve puzzles with numbers. There are random numbers all over the board, as well as numbers on the side. All the numbers need to make a sum of the numbers on the sides of the rows and columns.

Find out in this fun math game

How to play Sum Master

Sum Master is all about math and quick thinking. You need to figure out which numbers you need to select in the board. The numbers in the board that you have selected need to be the same added up together as the number on the side of that column, or on the top of the row. Figure out which numbers you need to select each round, and don’t lose all your hearts! 

You have 3 hearts each round. If you make a mistake by selecting the wrong number, you lose one of them. If you lose them all, you get a game over. So try not to make any mistakes. Start off with the easy levels, that are easy and quick to figure out. But the later levels get more difficult. New gameplay elements make those levels even harder!
You get areas of the same color. On the most top left square of that area is a number as well. The selected numbers in that area need to be the same summed up as the number in the top left corner.

Good luck in Sum Master, and use your math skills to finish all the levels in record time!
