在线光轨对决：你和电脑各驾驶一辆光速摩托，在网格赛场上不停前进，身后会留下一道无法穿越的光墙。转弯把电脑逼进死角，让它先撞上光墙或边框就赢了。可选三档速度和电脑难度，键盘方向键、滑动屏幕或方向按钮都能操作，记录胜负战绩。Light Trails online: you and the computer each ride a light bike that never stops moving and leaves an impassable wall of light behind it. Turn to box the computer in and make it crash into a wall or the edge first. Three speeds and three computer levels; steer with the arrow keys, a swipe or the on-screen pad, with your win/loss record kept.
方向键 / WASD 或滑动屏幕转弯，摩托不能直接掉头。P 暂停，N 重开。Turn with the arrow keys / WASD or by swiping — bikes cannot make a U-turn. P pauses, N restarts.
玩法说明与常见问题How to play & FAQ
「光轨对决」怎么玩？How do I play Light Trails?
你是青色的摩托，从左边出发向右；电脑是橙色，从右边出发向左。双方速度相同，每一格都会留下光墙。尽量占据大片空地，再把电脑引向狭窄的区域；如果双方同时撞毁就是平局。You are the cyan bike starting on the left heading right; the computer is orange, starting on the right heading left. Both move at the same speed and every square leaves a wall. Claim big open areas and steer the computer into narrow ones; if both crash at once it is a draw.
电脑会预判吗？Does the computer plan ahead?
中等和困难难度会计算每个方向剩余的空间，困难难度看得更远；简单难度偶尔会乱转。On Normal and Hard it measures the open space in each direction, looking further ahead on Hard; on Easy it sometimes turns at random.
可以连按两次转弯吗？Can I queue two turns?
可以，快速连按两次方向键会在接下来两步依次转弯，适合急转。Yes — two quick presses turn on the next two steps, handy for tight corners.
