The number of attempts can vary due to the initial or near-initial outcome.The first version of Level 965 and the second version of Level 160 King usually will notice Nearly Impossible levels and nerf them.Great luck, often lottery-level is usually required.The probability of succeeding is extremely low, almost impossible.Can take up to many hundreds of attempts, up to thousands, and so on.
However, the chances are too low that it should be nerfed. Theoretically possible to complete the level without boosters and cheats.
Impossible levels: If an episode contains an impossible level, the difficulty of the episode is also impossible and the mean cannot be calculated, the episode has an undefined value. Variable levels are also not included in the sum that we have to divide to calculate the episode mean, as if the episode has <15 or 20 levels. If an episode contains variable levels, we must subtract the number of variable levels from the size of the population (Aka the number we have to divide by during the final operation). (Note: In the first two episodes, we must divide the sum by 5 or 10 (depending on the episode) instead of the usual 15, and in episodes 37-62, we must divide the sum by 20). The final number we'll get, which is rounded to the hundredth decimal place, is the arithmetic mean of that episode. Then, we must add up the 15 (Usually) numbers (Aka calculate the sum of the 15 numbers) and we must divide the number we'll get by 15 (Usually). The higher the difficulty, the higher its number. It's different for variable levels, explained below).
To calculate the mean of each episode, we must first remember how to convert each difficulty level into its given number (Noted above, in the "Difficulty code usage" section. The overall difficulty of the episode is also determined by it. An important thing that comes with level ratings is episode means, the indicator of how hard each episode is on a scale of 0 to 9.
