Load a game

Open on barricade.gg ↗

A shared barricade.gg/analysis link carries its own moves, so it loads without an account. Moves can also be pasted straight in, either as e2 e8 e3h or as this engine’s own U D H42. A bare share code has to be fetched from barricade.gg, which browsers block on a site that is not theirs — paste the moves instead.
