Welcome to this cute addition game!
In this game, you will need to meet some different numbers in a normal size matrix or a bigger size (maybe it's not hard!) matrix. You can try some simple clicks.
When you click the number, all the surrounding numbers will be added into the number you clicked. If you click the upper right corner of the normal matrix, only 4 numbers will be calculated. But, if you play the harder mode with larger matrices, when you click the center number all the 9 numbers will be calculated. I really hope you can understand my meanings.
So, go ahead and keep your brain young. Once you master this game you will be glad to have this smart addition ability.
