How to play?
When you launch "Sum Master", you'll see a playing field divided into cells with numbers. Look to the right of each horizontal row—a number acts as a hint, showing how much you should get if you add all the numbers. The same applies to the top of each vertical column, where a hint indicates the sum of the numbers in that column. But that's not all! There are also colored areas, and each has a small number hidden inside—the sum you need to reach by adding the numbers within that area. You need to select numbers so that all of these sums match the hints. Think carefully about which numbers to choose to solve this puzzle! Ready? Let's go!
