Coin Master Merge Island Arcade Calculator [ 13 Levels ]
The Lightning Formula: The Path to Level 13To reach the ultimate goal of level 13 on the Kombi Arcade Island, you need to master the mathematics of doubling.
Every symbol you combine is the result of an exact chain of lightning bolts.
To unlock the ultimate reward of the 13th level on the Kombi Arcade 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 linearly, but exponentially.
It all starts with your first lightning bolt. This generates a level 1 basic symbol. To reach the next level, this cost doubles every time. While level 2 only costs you a modest 2 lightning bolts, you will already notice by level 5 that the journey is getting more demanding.
Exponential Growth
Since you need two symbols of the previous stage for every higher symbol, the costs per level double. While level 2 only costs 2 lightning bolts, level 6 already requires 32 lightning bolts, and level 10 a whopping 512 lightning bolts.
The Goal
For the final symbol of level 13 you need to combine multiple symbols. This means an investment of multiple lightning bolts to complete the entire combination chain from start to finish.
Pro Tip from the Kombi Master
⚠️ Keep an eye on your game board! Since you need on average between 1050 and 1150 clicks, you should use your lightning bolts in stages so as never to lose space for new combinations. Anyone who calculates cleverly clears away the small levels immediately to make room for the big leaps.

Take your chance: By using x1, x2, x4 or x8 multipliers, the required amount of lightning bolts can vary. With the right strategy, you can reach your goal often with 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 – 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.
ℹ️ 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.
ℹ️ 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.
