6/24/2023 0 Comments Solitaire peg board game rulesThis can be demonstrated through the following argument. leaving the centre hole empty, and playing to leave a single peg in the centre hole). The same notation can be used for the 37-hole board the only difference is that b2, f2, b6, and f6 represent squares on the 37-hole board but not the 33-hole board.įor the 37-hole game, there is no solution for the centre-complement game (i.e. For example, the central square can be denoted as d4. Several different systems of notation are in use the one used by Beasley in The Ins & Outs of Peg Solitaire labels the seven columns a through g and the seven rows 1 through 7, so each hole is denoted by its row and column reference. The 33-hole board has come to be the standard-sized board in most countries, although the 37-hole board is the most common board in France and can be found elsewhere.īefore discussing a solution, it is convenient to introduce a suitable notation. The 33-hole board was first mentioned in Unterricht in der natürlichen Magie by J. The board shown in the engraving mentioned above is the 37-hole board. Because of the simplicity of the game, it is not inconceivable that some version of this game could have been played well before these dates, however. The earliest known reference to the game is the 1697 engraving Madame la Princesse de Soubize joüant au jeu de Solitaire by Claude-Auguste Berey, and the earliest textual reference was written by Gottfried Leibniz in 1710. Many legends as to the game's origins exist, but all lack evidential support. The game, and the solvability of various positions, are also of mathematical interest. The objective of the game is to remove all the pegs but one, and have the remaining peg end up in the centre square of the board. Moves are made by jumping one peg over another horizontally or vertically, and removing the jumped peg. While many different boards exist, the most common is played on a 33-hole board. However, solving the game is more complicated than it looks. Its straightforward rules have made it a widely-played game, with millions of sets in existence, a set being a not-uncommon present. For some initial configurations there is no solution.Peg Solitaire (in British English referred to as just Solitaire, while the latter term, in American English, refers to the type of card game known in British English as Patience) is a single-player board game. The code allows you to test any board configuration, and the algorithm will check if there is a solution to this sequence of pegs on the board. Results: within about 15 seconds the program is finding a solution and prints it out in the form of moves. However, the final result looks slightly different. This pseudo code was used as an inspiration for the program. Storing information about already taken paths is implemented with a hash table. However, this is not enough to call it a good algorithm because it does not solve the problem in a reasonable time.Īnother improvement is needed - making an informed search which checks to see if a given board configuration was already checked, and if so, does not continue a search on that path. In a proposed solution, a “depth first” search is used ( ) which tries to search (make trial moves) as deeply as possible, and backs up only when it hits a dead end, at which point back tracking is used ( ). (Source: ).Īn algorithm which blindly checks all the possibilities will not work quickly, and even with a very fast machine it would take years to solve. The game is won when all of the pegs are removed except one, which is in the center hole.įor the version with 33 holes (and 32 pegs) of Peg Solitaire there are 577,116,156,815,309,849,672 different game sequences (577+ quintillion possible games), with 40,861,647,040,079,968 solutions. Play continues with a peg jumping over another peg into an empty hole until there are no possible moves left. A peg can only jump one peg at a time, but as with Checkers, a peg can make a series of multiple jumps if there are open holes. A peg can jump left, right, up or down but cannot jump diagonally. The first move begins with a peg jumping over another peg into an empty hole. The game starts with all the holes on the board filled with a peg except the hole in the center, which is empty. Once a peg has been jumped over, it is removed from the board. The rules of Peg solitaire are similar to Checkers, in that a peg can jump over another peg as long as there is an empty hole on the other side. The first evidence of the game can be traced back to 1697. The game is also known as Brainvita (especially in India). In the United Kingdom the game is referred to as Solitaire while the card games are called Patience. Peg solitaire (or Solo Noble) is a single player board game involving movement of pegs on a board with holes. C++ program solving Peg solitaire game About Peg Solitaire.
