Pente was created in 1978 by Gary Gabrel from Stillwater, Oklahoma, USA.
Pente is close to Japanese game of ninuki-renju.
There are two ways to win the game:
Win by getting five-(or more)-in-a-row,
either horizontally, vertically, or diagonally, with no empty
points between the stones, or
Win by capturing five (or more) pairs of
your opponents stones.
Playing begins in the center of the board
Whenever your opponent has two stones (and
only two) which are adjacent, those stones are vulnerable to
capture. The pair can be captured by bracketing its two ends with
your own stones.
By placing stone in *, captures a pair of opponent's stones.
A stone may legally be played onto any empty
intersection, even if that point has been previously occupied,
and even if forms a pair between two enemy stones. No capture is
made by the enemy in that case.
Multiple captures are legal.
Pente-board has 19 vertical and 19
horizontal lines like the Go-board.
This is official rule.
Using our software you can play Pente in board with other sizes.
White starts the game which differs from
Renju and Go.
The player moving first has a distinct advantage.
The tournament rule decrease deferences between black and white.
The tournament rule was created by Tom Braunlich.
The tournament rule:the 3rd move Black must make outside the
zone of 5x5 intersections with the same center as the center of the whole board.
The 5x5 zone is a prohibited zone.
G-Pente is a variation of Pente proposed by Gary Barnes.
The tournament rule + it additionally prohibits for 3rd move playing on the
4th and 5th intersections away from the center of the board that are on the same horizontal or vertical line.
The reason for the variation is to make the game more fair for second player
