Twixt is played on board with a 24×24 grid of holes, with the four corners missing. The two players are Red and Black; the topmost and bottommost rows belong to Red, and the leftmost and rightmost rows belong to Black. (Different sets may use different colors.)

The rules are as follows:

• The players take turns placing pegs of their respective colors on the board, one peg per turn.
• A player may not place a peg on the rows which belong to his or her opponent.
• Red places the first peg. To counteract first-move advantage, the pie rule is suggested. (One-move equalization is part and parcel of the original rules as written by Randolph, but some sets sold in the US did not mention it.)
• After placing a peg, you may link one or more pairs of pegs on the board which are all your own colour. The links can only go between two pegs a knight's move away from each other, and cannot cross another link; they block other links, most importantly the opponent's. You may remove your own links (but not your opponent's) in order to rearrange the sequence of links on the board.
• The first player to make a continuous chain of linked pieces connecting their two sides wins. If neither side can achieve this, the game is a draw.
