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.
