Castles 囲い
Step through how each castle is built, one move at a time. Only the builder's moves are shown — the opponent stands still — so you can see the shape form. In a real game you play these between your opponent's moves, and the order bends to what they do.
Use the arrows, the ← → keys, or swipe the board.
