Hex Connect

A classic connection game on a board of hexagons. Side A links the left and right edges, side B links the top and bottom. Every stone you place helps you and blocks them.

Join your two edges with an unbroken chain of hexagons before your opponent joins theirs.

The computer ranks moves by how short each side's best connection would be and samples random finishes; it is a decent opponent, not perfect play. Moves: 0.

Side A to move (you).

Controls

  • Tap an empty hexagon to place a stone.
  • With the keyboard, Tab to the board, move with the arrow keys (left and right change q, up and down change r) and press Enter or Space.
  • After the opening stone, Swap sides lets the second player take that stone's side instead of placing. Undo and New game are always available.

The rules

  • Players take turns placing one stone of their side on any empty hexagon. Stones never move or get captured.
  • Each hexagon touches six others. A side wins by linking its two edges with an unbroken chain of its stones.
  • The swap rule balances the first-move advantage. The board can never fill up without somebody winning, so there are no draws.

Scoring, saving and limits

A game is won or lost; there is no score. Results are not ranked or shared.

Your current game, opponent and board size are kept on this device only. Download a backup to move them.

The computer combines a shortest-connection estimate with a limited number of random play-outs. It does not play perfectly and no claim is made that it does. Twelve tactical positions are included as starting points.

Questions

Who wins if the board fills up?
That cannot happen without a winner — a full board always contains exactly one connection.
What does swapping do to the stone?
Nothing. The stone stays where it is and keeps its side; the two players exchange which side they play.
Why is the board slanted?
Hexagons tile into a rhombus. The slant is only drawing — which cells touch never changes.
