Even and Odd
Number 8 checkers and pile
them up as shown. Use a minimum of moves to shift checkers 1, 3, 5, and 7 from
the center to the “Odd” side circles and checkers 2, 4, 6, and 8 to the “even”
side circles. To move, shift the top checker from one pile to the top of
another. It is against the rules to put a checker with a higher number on a
checker with a lower one, or to place an odd-numbered check on an even0numbered
checker or vice versa.
Thus, you can put checker 1
on 3, 3 on 7, or 2 on 6 – not 3 on 1 or 1 on 2.
