怎么玩How to play
用手指拖动棋子，每走一格算一步，可以拐弯。让汉塞尔（蓝）和格蕾特（粉）从下方 b 列的出口逃出去。棒棒糖只能走一格，掉进洞里就锁住了；糖果屋不能动。电脑上也可以点选棋子后用方向键，Z 撤销。Drag a piece with your finger — each square is one step, and a move may turn corners. Get Hansel (blue) and Gretel (pink) out through the exit under file b. A lollipop can take only one step, then drops into a hole and locks; the Candy House never moves. On a computer: click a piece, use the arrow keys, Z to undo. 完整规则与记谱法 →Full rules & notation →
