Leapfrog Race · 单线跳棋
A single line of nineteen spots. You may leap the other player but never your own, so a traffic jam of your own making is fatal.
十九个点排成一条线，跳得过对方却跳不过自己人：最要命的堵车都是自己造的。
沿一条直线赛跑，跳过对方棋子
Race down a line, leaping over the other player
玩法要点
- 棋子：双方各 5 枚
- 棋盘：一条直线，19 个棋位
- 获胜：5 枚全到对面；无路时比进度
Quick start
- The first player to get all 5 pieces across to the far end — the 5 spots where the other player started — wins.
- Move one of your own pieces. It can only go forward.
- If the spot right ahead is your own piece, that piece simply can't move — you can't leap over your own pieces either.
快速上手
- 谁先让自己的 5 枚棋子全部抵达对面（也就是对方一开始摆棋子的那 5 个棋位），谁就获胜。
- 每次只走一枚自己的棋。只能往前走，不能后退。
- 如果正前方是自己的棋子，这枚棋子就完全走不了，也不能跳过自己的棋子。
Rules
Board and Setup
The board is a single line with 19 spots in a row.
One player's 5 pieces start on the 5 spots closest to their own end; the other player's 5 pieces start on the 5 spots closest to the other end. The middle stays empty.
Movement
Move one of your own pieces. It can only go forward.
If the next spot is empty, move there.
If enemy pieces are in front and an empty spot is just beyond them, leap over them.
Leapt-over pieces stay on the board. They are not captured.
Special Rules
If the spot right ahead is your own piece, that piece simply can't move — you can't leap over your own pieces either.
Each turn is just one step or one leap. You can't chain multiple leaps together in the same turn.
Winning
The first player to get all 5 pieces across to the far end — the 5 spots where the other player started — wins.
If someone has no move before either side gets all 5 across, compare progress: first count pieces already at the far end, then count how far every piece has travelled. The side farther ahead wins.
Timer
Each turn lasts 60 seconds. When time runs out, the turn passes to the other side automatically.
You can change the difficulty anytime in Game Settings.
规则详解
棋盘与开局
棋盘是一条直线，一共有 19 个棋位。
一名玩家的 5 枚棋子摆在自己这一端最近的 5 个棋位上，另外一名玩家的 5 枚棋子摆在另一端最近的 5 个棋位上，中间留空。
行棋规则
每次只走一枚自己的棋。只能往前走，不能后退。
前面是空位，就向前走一格。
前面连着对方的棋、后面有空位，就能跳过去。
跳过的棋不离开棋盘。它没有被吃掉。
特殊限制
如果正前方是自己的棋子，这枚棋子就完全走不了，也不能跳过自己的棋子。
一次只能走一步或者跳一次，不能连续跳好几段。
胜负条件
谁先让自己的 5 枚棋子全部抵达对面（也就是对方一开始摆棋子的那 5 个棋位），谁就获胜。
要是有人没路走、又还没人把 5 枚都送到对面，就比谁跑得更远：先数谁已经到对面的棋子更多；一样多，就数全部棋子走过的格数。跑得更远的一方获胜。
计时
每步限时 60 秒，时间到了会自动换对方走。
可以在"对局设置"里换一个难度，随时都能换。
