A checker is promoted to a king when it moves to the other end of the board. A king is usually distinguished from the other pieces by stacking two checkers. As per international rules, a king can travel any number of squares in a diagonal.

The objective of checkers is to get as many kings as possible and try to defeat the opponent. You want the opponent to have zero checkers and you have more than zero.
It is physically impossible to fold a piece of paper in half more than 8 times. However, assuming you could do it (though it would be easier to cut the pile so far in half and put one half on top of the other), then: After 1 fold the stack has 2 sheets After 2 folds the stack has 4 sheets After 3 folds the stack has 8 sheets After n folds the stack has 2^n sheets After 50 folds the stack will be 2⁵⁰ sheets thick As each sheet is 0.1mm, the stack will be: 2⁵⁰ × 0.1 mm = 112589990684262.4 mm thick = 112589990.6842624 km thick ≈ 1.126 × 10¹¹ m thick

Technically, this is impossible as two checkers will always lie in a row. However, how about like this: ................... . @ ............. ..@ @ ......... ..@ ... @ ..... ..@ @ @ @ . ................... (@ = checker) (. = table top, used to ensure picture stays as designed)
When you jump over two pieces of your opponent's. You stand up and show them your rear. That's the "rainbow" move in checkers.
