Garden Hex is a Hex board game online where every stone helps build a route between two opposite edges. White connects N to S; black connects W to E. Choose a complete 11×11 game against the computer or a friend sharing your device, or learn with twenty separate 4×4 connection challenges.
Read your player number, stone color and target edges above the board. White connects the edges labeled N and S; black connects W and E.
Place one stone in any empty hex on your turn. Each cell touches up to six neighbors. Stones stay where they are placed.
In a full game, Player 2 may swap colors instead of placing after the opening stone. Both players exchange colors and target edges; the first stone stays put and Player 1 takes the next turn.
Connect your pair of edges through an unbroken chain of your stones to win. A chain may bend; it does not need to form a straight line.
Use Undo to review a turn or Hint to mark a suggestion. Complete a teaching challenge to unlock the next one; full games keep their progress separate.
Controls
Tap or click inside a hex to place a stone. On a focused board, arrow keys move the outlined cell and Enter or Space places there. Previous empty, Next empty and Place focus provide button controls. Swap colors appears as an available action only for Player 2's first decision. Hint outlines a suggestion; Play hint performs it. Undo, Pause, sound, Restart, Help and Full screen are beside the board.
A tip before you start
Plan connections in more than one direction. Two nearby groups may be able to meet through different empty cells, making them harder to block. Check the edge labels after a swap: your player number stays the same, while your stone color and destination pair change.
A connection game on a complete 11×11 board
Standard games start with all 121 hexes empty. There is no gravity, capture, line-length requirement or tile clearing. Place freely on any empty cell and connect your assigned edges through the six-neighbor grid. The first connection ends the game immediately. A complete Hex game cannot be a draw.
Two players on one device, or a bounded computer opponent
Two players take turns on the same screen; there are no remote rooms or online matchmaking. Vs computer makes you Player 1 and the computer Player 2. The computer compares legal choices with a connection-distance strategy within a fixed search budget. It can make mistakes and is not claimed to play Hex optimally.
What the opening swap changes
Player 2 has a one-time pie-rule choice immediately after the first stone: place normally, or exchange colors with Player 1. Swapping consumes that turn. The opening stone remains in its original hex, now belonging to the other player. Player 1 then places the opposite color. No later turn can swap, and Undo can restore the position and both players' color assignments.
Twenty verified 4×4 teaching challenges
Challenges use a clearly labeled 4×4 board rather than pretending to be shortened standard games. Each starting position comes from legal alternating play and has a strategy that wins against every legal opponent response. The fixed proof search takes strictly more work across the twenty positions, from 2 visited nodes to 220; the empty-space count also grows from four to ten. This measures a consistent planning task, not a promise that every later puzzle feels harder. Your own mistakes can still lead to a losing position. Full 11×11 games never unlock these challenges.
Free browser play with a compact board
Play free, with no download, account or ads. The board uses separate desktop and portrait layouts, and all hexes remain inside the game window. Stone letters and edge labels identify both goals without relying on color alone. Help opens separately and cancels any pending touch. There is no clock or life limit.
Frequently asked questions
Can I play the Hex board game online free?
Yes. Open Garden Hex and choose Challenges, Vs computer or Two players. The game is free in your browser and does not need an account or installation.
Is this Hexa Sort or a hexagon block puzzle?
No. This is the two-player connection board game Hex. You place one stone per turn and connect your opposite edges; there is no sorting, stacking or clearing tiles.
Can I play a friend remotely?
This version supports two players taking turns on the same device. It does not provide remote multiplayer, invitations or matchmaking.
Why did my color change after Swap?
The second player used the opening pie rule. The players exchange colors and target edges, while the existing stone stays in place. Player 1 makes the next move with the other color. The labels above the board always show the current assignments.
Does Undo include the computer's move?
Yes. In Vs computer and Challenges, Undo restores your previous action and the computer response that followed, including an opening swap. In Two players it restores the most recent single action.
What does the game remember after a reload?
Unlocked challenges, best scores and sound settings are stored locally when browser storage is available. Reload opens a fresh first challenge; it does not restore an unfinished full game. Restart and changing modes ask for confirmation.
Are hints and the computer always optimal?
The full-game computer and its hints use a limited connection-distance search, so they can be beaten. Small-board challenges use exact win/loss search. If an exact search reaches its budget, the game reports that limit instead of awarding an unverified result.
