Numbubbles Popping

Numbubbles Popping is a logic-based and mathematically-based game. To get started, you just aim one numbubble, select the desired arrow direction, and fire the numbubble in the direction of another. If both numbubbles have different numbers on them, they will be merged into one, and the new numbubble will have the total of the numbers from both of the original numbubbles. If the numbers on both of the numbubbles are the same, then both of the numbubbles will be removed from the game. Your objective is to clear the board of all numbubbles; therefore, you need use some critical thinking before deleting or merging any pairs.
