The Bolt Formula: The Path to Level 13To reach the ultimate goal of the 13th stage on Merge Island, you must master the mathematics of doubling.
Every symbol you combine is the result of an exact chain of Bolts.
To unlock the ultimate reward of the twelfth stage on Merge Island, you must 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 evenly, but exponentially.
It all starts with your first Bolt. This generates a level 1 base symbol. To reach the next stage, this input doubles every time. While level 2 only costs you a modest 2 Bolts, you will notice by level 5 that the journey becomes more demanding.
Exponential Growth
Since you need two symbols from the previous stage for each higher symbol, the costs per level double. While level 2 only costs 2 Bolts, level 6 already requires 32 Bolts, and level 10 requires a proud 512 Bolts. Therefore, it is exponentially important, especially in higher levels, that you merge the Bolts to collect the maximum profit of 35 
Bolts, which will bring you faster and easier to your desired goal.
The Goal
For the final symbol of Level 13 you have to combine several symbols. This means using an input of multiple Bolts to complete the entire merging chain from start to finish.
Pro Tip from the Merge Master
â ī¸ Keep an eye on your board! Since you need between 950 and 1050 clicks on average, you should use your Bolts in stages so that you never lose space for new combinations. Those who calculate smartly clear away the small levels immediately to make room for the big leaps.

Take your chance: By using x1, x2, or x4 multipliers, the required amount of Bolts can vary. With the right strategy, you will often reach your goal using significantly less energy than calculated in the standard cost overview!
Merge Island Calculator Pro
Your game board is your starting capital: Theoretically, a 
symbol costs 4.096 lightning bolts â 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 generate them all. As soon as you enter your current inventory 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 bolts.
âšī¸ For symbols on your board, activate the "Next Degree" checkbox if you intend to complete that symbol next. The corresponding symbol will then be automatically doubled to provide a more realistic calculation for your board.
âšī¸ Capture and double inactive values: Here you can record symbols that are present on your board but are not currently in your active possession, allowing them to be included in the calculation.
