⚡ The Energy Formula: The Path to Level 12To reach the ultimate goal of Level 12 on Merge Island, you must master the mathematics of doubling.
Every symbol you combine is the result of an exact chain of 
Energy.
To unlock the ultimate reward of the twelfth stage on Merge Island, you need to understand the principle of doubling. Since each new symbol is created from two identical symbols of the previous stage, the energy requirement does not grow steadily, but exponentially.
It all starts with your first Energy. This generates a basic Level 1 symbol. To reach the next level, this investment doubles every time. While Level 2 only costs a modest 2 Energy, you will notice by Level 5 that the journey becomes more demanding.
Exponential Growth
Since you need two symbols from the previous level for each higher symbol, the costs per level double. While Level 2 only costs 2 Energy, Level 6 already requires 32 Energy, and Level 10 a staggering 512 Energy.
The Goal
For the final symbol of Level 12, you must combine multiple symbols. This means an investment of several Energy to complete the entire merge chain from start to finish.
Pro Tip from the Merge Master
⚠️ Keep an eye on your board! Since you need over two thousand clicks, you should use your Energy in stages to never lose space for new combinations. Those who calculate cleverly clear away small levels immediately to make room for the big leaps.
Multiplier Bonus
Seize your chance: By using x1, x2, or x4 multipliers, the required amount of Energy can vary. With the right strategy, you can often reach your goal with significantly less energy than calculated in the standard cost overview!
Merge Island Calculator Pro
- symbol costs 2,048 lightning bolts – but only if you were starting from scratch. Since your Coin Master island board is already populated with many symbols, you don't have to painstakingly generate them. As soon as you enter your generated symbols and the ones Coin Master has stored into the calculator, it subtracts the value of your existing symbols from the total. In practice, this often reduces your energy requirement to below 1,000 lightning strikes, as you already have a large part of the combination chain on your field.
