Five-in-a-row games are very old. In Japan they have been played on the 19x19 Go board for over a thousand years under the names Gobang and Gomoku.
The rules were simple: players alternate to put a stone on a
vacant point, and the first player to get an unbroken row of 5 stones, horizontally, vertically or diagonally, wins. In the year 1899 the Japanese players began to play more organized, so they changed the name for serious playing from Gomoku to Renju, five pearls, in a row. In Renju the first player is subject to a number of handicaps, to ensure balanced play. Pente was introduced by Gary Gabrel from Stillwater, Oklahoma, USA at the end of the seventies and became very popular in the USA in the first half of eighties. The game adds an interesting twist to the general five-in-a-row idea: pairs of opponent's stones that are straight or diagonally adjacent can be captured in the 'custodian fashion', that is: by sandwiching them between two of one's own stones. As in Othello, it is the act of sandwiching that brings the capture: black can make a double capture at A, white can play safely at B.

In 1983 Gary Gabrel, then president of Pente Games, Inc. announced the sale of Pente to Parker Brothers Game Co., who are the current copyright holders. In 1984 Rollie Tesh, former Pente champion, suggested "Keryo Pente", in which the capture of triplets is also allowed. This effectively prevents a well known defense in regular Pente: extending a threatened pair to make it a triplet. The alternative to a line of 5 is now 15 stones. All three variants can be played with the Pente applet. More information about the games can be found at The Renju International Federation |
