Once there where two men playing checkers. at one time during the game. one of them stopped and said "Look at that, we just arranged twelve checkers in six straight lines of four". Then they finished their checkers game without any more interruptions.

Now assuming that the man was telling the truth, and they were playing the game correctly. how is this possible?

P.S. this problem is also possible with thirty checkers and six lines of seven. (in the exact same scenario). And don't worry this will fit on the board.

    $\begingroup$ @VHS: No, that's not true. This is a puzzle that requires knowledge of something else, but is not only "identify this thing". Your puzzle was not a puzzle - it was just an exercise in Googling things. $\endgroup$

The reason they could do this is because

they were playing the game called Chinese Checkers, which is played on this board:enter image description here
They simply made a "Star of David" shape (six marbles in a hexagon, then six more marbles each touching exactly two of the inner marbles).

  • $\begingroup$ great job, exactly the right answer. but you can do it on a normal checkers board. $\endgroup$
