Claim vertices joined to your own. Whoever has nowhere left to go loses.

Rules
Fjords is played on a board of 64 vertices in offset rows, where most neighbouring vertices are joined by an edge. Blue and Red each start with three vertices, and Blue moves first. In turn, each player claims an empty vertex joined by an edge to one of their own. A player who cannot claim a vertex on their turn loses.
Once no region of empty vertices can be reached by both players, the game is settled: each player has as many moves left as there are vertices in their regions. So the player with more of them wins, and with as many, the player to move runs out first. The page ends settled games unless you choose to play them out.
Playing
Click a vertex to claim it. A seed deals the board, so the same seed gives the same board, which the address of the page keeps. The AI is a neural network trained by self-play, which picks its moves with a Monte Carlo tree search in your browser. More simulations make it stronger, and slower.
