General formula:
Score = Round value ((Filled cells/Overall amount of empty cells) * 100)
- We are looking for all the cells that were empty at the very beginning of the game
- We find all the cells that are filled correctly and without any hints
- We divide all the correct answers (cells) into the number of empty cells
- Multiply the result by 100
- Rounding to the integer value
- Bonus = correct answers were made without any hints
Example:
- Empty cells = 38
- Correct answers = 3
Score = Round ((3/38) * 100) = 8
