Game Numbubbles Popping

Numbubbles Popping is a logic math game. To get started, simply aim at a number bubble, set the direction of the arrow, and shoot the number bubble at another. If both number bubbles have different numbers, they will be merged and the resulting number bubble will have the sum of both numbers. If both number bubbles have similar numbers, both number bubbles will be removed. Your goal is to remove all numb bubbles, so think logically before merging or removing a pair.
