The essence of the game - it is necessary to cross out all digits from the game board. At that it is possible to mutually delete identical digits (for example, 2 and 2) and digits giving in total 10. The numbers are crossed out according to the following rules: standing next to each other diagonally, vertically, horizontally, as well as the last in the line and the first in the next line. This is a variation of the game "Seeds" with its own peculiarities and chips. Translated with DeepL.com (free version)
Look for identical pairs of numbers or pairs of numbers whose sum is 10: 1 + 1 2 + 2 3 + 3 4 + 4 5 + 5 6 + 6 7 + 7 8 + 8 9 + 9 1 + 9 2 + 8 3 + 7 4 + 6 5 + 5 Pairs can be horizontally, vertically and diagonally. The main thing is that there are no other untidy numbers between them.
