Addition Frenzy HD

Dog and Owl want to see what's in the box, but it's all covered by numbers. Help Owl pick numbers that add up to what Dog is thinking and reveal the hidden picture!
Choose up to 4 numbers to reach the target sum and earn points. How quickly can you add the numbers to get the right total? The faster you are, the higher you score. Clear the board before the timer runs out to reach the next level and uncover another picture. As the levels progress, the target gets bigger and the time gets shorter!
