This is an interesting mind game which enhances your analytical skills and also helps you to calculate in real time speed. This game is suitable for any age group and like an exercise which keeps your mind active all the time. Whenever you get bored, this is the game you are looking for. 

So let's brief you regarding the game and how it actually works:
The game works on basic arithmetic operations. You simply need to tap or shoot a number from a lot, which you think is best in order to get maximum. But there are certain basic rules around which the game revolves and these are strict to be followed. 

For that you need to understand three basic rules which are as follows:
1. If you tap the extreme left digit, the number to the immediate right gets added up to the current.
2. If you tap the extreme right digit, the number to the immediate left gets added to the current.
3. If you tap any middle digit, the multiplication of the neighboring numbers gets multiplied and adds up to current.

[NOTE: If only one digit gets left, that only gets added to the current and gives you the final value.]

* If the current value matches the final objective value(Max), you get +1 Score.
* Also if you perform well in all your games at a certain level, you are promoted to the next advanced level with more bubbles and restrictive timings.
