🔦 激光反射Laser Mirrors
在线激光反射益智游戏：激光从左侧射入，碰到斜放的镜子就会转 90 度。点一下镜子可以切换它的方向（/ 和 \），你要调整所有镜子，让激光一次穿过全部蓝色水晶。灰色方块会挡住光线，多余的镜子可能是干扰项。12 个关卡从 5×5 到 8×8，卡住时可以用提示。Laser Mirrors online: a laser enters from the left and turns 90 degrees whenever it hits an angled mirror. Tap a mirror to flip it between / and \, and set them all so the beam passes through every blue crystal in one go. Grey blocks stop the light and some mirrors are decoys. Twelve levels from 5×5 to 8×8, with hints if you get stuck.
点镜子切换方向，激光的路线会实时更新；被照亮的水晶会发光。R 重来。Tap a mirror to flip it and the beam updates instantly; lit crystals glow. R restarts.
玩法说明与常见问题How to play & FAQ
「激光反射」怎么玩？How do I play Laser Mirrors?
激光沿直线前进：遇到“/”镜子时，向右走的光会转向上，向下走的光会转向左；遇到“\”镜子时，向右走的光转向下。光线可以穿过水晶继续前进，碰到灰色石块或射出边界就结束。从激光入口开始，一面一面地调整镜子，让光线依次经过所有水晶。The beam travels in straight lines: a "/" mirror turns a rightward beam upward and a downward beam to the left; a "\" mirror turns a rightward beam downward. Light passes through crystals and keeps going, and stops at a grey block or the edge. Work outward from the laser, setting one mirror at a time so the beam visits every crystal.
每关只有一种解法吗？Is there only one solution?
不一定。只要激光同时经过所有水晶就算过关，有的关卡有多种摆法。Not necessarily — any arrangement that sends the beam through all the crystals counts, and some levels have several.
提示是怎么工作的？How does the hint work?
提示会把一面方向不对的镜子转到参考答案的方向。A hint flips one mirror that differs from the reference solution into its correct direction.
