A connection game is a game where the goal is to use the pieces to create a connection between some parts of the board. The first connection game was Hex, which was invented in 1942. Several others have been created since then.
- Hex (Piet Hein 1942 and John Nash 1948)
- The original connection game. Played on a rhombic hex grid.
- Y (Craige Schenstead and Charles Titus, 1950s)
- Played on a triangluar grid of hexagons
- Twixt (Alex Randolph, 1960s)
- Played on a square grid of holes into which the players place pegs. The pegs can be connected via bridges; a bridge connects two holes that are separated by a knight's move.
- Havannah (Christian Freeling, 1980)
- Multiple goals, two connection-oriented and one shape-oriented.
- Quax (Bill Taylor?, 2000?)
- Played on a square grid with the possibility of diagonal connections.
- Onyx (Larry Back, 2000)
- Played on an original grid consisting of both triangles and squares. It is the first connection game with a capturing rule.
- Gonnect (João Pedro Neto, 2000)
- This game is simply Go, but with a different goal, namely to create a connection between any two opposite sides.
- Unlur (Jorge Gómez Arrausi, 2001)
- Played on a hexagonal hex grid. Unique in the way that the players have different objectives.
- Connecto (unknown author, unknown year)
- Played on an interlaced square board.
- MindNinja (Nicholas Bentley, 2006)
- Generalized game of shape-building and connection, where board and win conditions are decided with help of a pie rule.
- Atoll (Mark Steere, 2008)
- A generalization of Hex to boards with four or more perimeter segments. With four segments, it is identical to Hex.
