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 →
答案Solution
最优解:16 步,5 次移动。先自己试试!Optimal: 16 steps in 5 moves. Try it yourself first!
点击某一步可跳到该步之后的局面;灰字是走完这一步的局面记号。Tap a move to jump to the position after it; the grey text is that position's notation.
