|TwixT is a two-player abstract board game played on a board with a square grid of holes that was invented by Alex Randolph in 1957 in the Vienna coffeehouse "Hawelka" as a paper-and-pencil game. This game is a member of the connection game family including such games as Hex, Y, Atoll and Crossway.
TwixT is played on a square board with a 24x24 grid of holes, with the four corners missing. Other sizes (e.g. 18x18) can also be used.
The four rows on the edges of the board are called border rows. The top and bottom edges are colored white while the left and right edges are colored black:

Below are two examples of a winning chain:
The game begins with an empty board.
Each player has an allocated color: White or Black.
Starting with White, players take turns doing the following actions:
Since the first player has a distinct advantage, the pie rule is used for making the game fair. This rule allows the second player to switch colors after the first player makes his first move.
