In either case, you are using a set of steps that can be generalized to solve all sorts of similar problems. Both versions of peg solitaire give kids a chance to develop, test, and improve algorithms for leaving one peg remaining.Īt first, kids will play the game more or less at random, hopping pegs wherever they see the opportunity. Simply put, an algorithm is a set of steps that one can use to solve a problem. Peg solitaire is a great way for kids to interact with algorithms. That's it!Īs with many of my favorite mathematical games, the rules are simple to explain, but the game itself is a challenge for kids and adults alike. Your goal is to jump these pegs over each other, one by one, until only a single peg is remaining. You may remove pegs by jumping pver them with another peg, as in checkers. I'm quite sure that the person who wrote that was just making shit up.In each game, the rules are the same. Possible but that there were only a few ways to do it, and now People start with E/H/I, which is perhaps why they always end upĪs an interesting (?) side note, it does notĪppear to be possible to jump the pegs in any way that results in Removing peg D (or, if you like, F or M). Therefore, the best bet for winning the game is to start by (Note: these are the "raw" numbers, not accounting for Might be inaccurate) the number of different winning combinationsĪnd the possibilities for the last position are largelyĭependent on what peg is taken out first. Together and not extensively checked, so the resulting numbers K and O are the same as A C, G, J, L, and N are all the sameĪs B F and M are equivalent to D finally, H and I can beĪccording to my script (which, I should add, was slapped Now, accounting for symmetry and rotation of the board, thereĪre four logically different starting points - A, B, D, andĮ. To simplify my description, I'll label the points the ![]() Here's the instructions on the Cracker Barrel game:īeing the hacker type, I wrote a little Perl script toĪnalyze the possible ways to jump the pegs so that one peg Proceeds in the same manner as the classic game by jumping To begin, the player removes any peg from the board. The pegs are arranged in a triangular fashion: ![]() Wangmu is a fifteen-peg game commonly found at the Crackerīarrel with which the idea is to jump pegs and end up with one The inverse of this statement is not so obvious, but has been proved mathematically.Ī variant on the "classic" peg solitaire layout described by Since forwards and backwards moves are special case of this inversion procedure, it's clear that if two positions cannot be transformed into each other this way, then they are not equivalent. (A backwards move is jumping a peg over an empty hole and filling the hole.) It can be proved that two positions are equivalent if and only if one can be transformed into the other by repeatedly taking any three adjacent pegs/holes and inverting them - replacing all the holes by pegs and all the pegs by holes. Two peg solitaire positions are sometimes said to be equivalent if one can be converted into the other by a sequence of forwards or backwards moves. ![]() One peg over another in a horizontal or vertical line, and removing the peg which was jumped over. The aim is to leave just one peg in the centre, by repeatedly jumping Of pegs - the diagram below shows the most common starting arrangement.
