Slither is a two-player abstract board game invented by Corey Clark in 2010. This game is a member of the connection game family, including such game as Hex, Crossway or Chain Lightning .


Slither is played on a square grid of 15x15 intersections.  Smaller boards (13x13 or 10x10) can also be used by beginners or for quick games. The left and right edges are colored white while the top and bottom edges are colored black:

Object of the Game

The goal of Slither is to form a chain of your stones connected orthogonally (horizontally, or vertically) linking the opposite edges of the board marked by your color.  A corner is considered to be part of both adjoining edges.

No draws are possible in Slither


The game begins with an empty board.

Each player has an allocated color: White and Black.

Starting with White, players take turns by performing the following actions:

  • a player may (but is not required to) choose to move one of his stones already on the board to an orthogonally or diagonally adjacent empty intersection.
  • a player must place a new stone of his color on any empty intersection of the board.

After the turn is complete, all of a player's stones that are diagonally adjacent must also be connected orthogonally through a common like-colored neighboring stone (otherwise the player's last move is illegal).

The pie rule is used for making the game fair. This rule allows the second player to switch places with the first player after the first player makes his first move, if he thinks that the first player has made an especially good move.
