10 - game number of childhood

Game 10 (The Ten) is the difficult, but very tightening logical game in numbers which has descended from school notebooks. To understand her and to be involved, it will be required to pass, at least the first level under the name "19". Game ten is so difficult that I will ask you: "And it is weak to you to pass all levels?"

Rules of the game The Ten: it is necessary to cross out all the numbers by two numbers equal to each other or equal to 10 (ten).

Example:

1) 1=1, 2=2, 3=3, 4=4, 5=5, 6=6, 7=7 ,8=8, 9=9;

2) 1+9=10, 2+8=10, 3+7=10, 4+6=10;

3) 6+4=10, 7+3=10, 8+2=10, 9+1=10.
