Beijing Tiger Chess · 北京老虎棋
The tiger starts caged. Keep it in and the dogs win; let it out and it only has to reach the far edge — or eat eight of them.
虎一开始关在笼里。关得住就是犬赢；一旦放出来，它只要冲到底排——或者吃够八只。
虎出虎笼，十五犬围追

玩法要点
- 棋子：虎方 1 枚，犬方 15 枚
- 棋盘：虎笼加 5×5 米字格，共 31 点
- 获胜：虎吃满 8 犬或冲到底排；犬困住笼内虎
Quick start
- The tiger wins by capturing 8 dogs or reaching the bottom row of the main board. While the tiger is still in the cage, the dogs win the moment it has no move left that leads out — even if the tiger can still shuffle between empty points inside the cage. A tiger stuck outside the cage draws the game instead.
- The tiger moves first. On your turn, move one piece one step along a drawn line to an empty neighboring point.
- When a dog is right beside the tiger and the next point in that same line is empty, the tiger can choose to jump over and capture that dog; the tiger can also choose not to capture it, and instead step to a different empty point next to it.
快速上手
- 虎吃掉 8 只犬，或走到主棋盘最下面一排，虎赢。虎还在笼子里时，如果下一步找不到任何一条能走出笼子的路（哪怕在笼子里还能挪来挪去），犬赢。虎在笼外没路走，算平局。
- 虎先走。轮到谁，就沿画好的线走一步，走到相邻空点。
- 虎紧挨一只犬，犬后面同一直线的点又是空的，虎这时可以选择跳过去吃掉这只犬；也可以选择不吃这只犬，而选择走到旁边其他相邻的空位。
Rules
Board and Setup
The small square at the top is the tiger cage. The board below it makes 31 points in all.
The tiger starts in the middle of the cage. The 15 dogs fill the bottom three rows.
How to Move
The tiger moves first. On your turn, move one piece one step along a drawn line to an empty neighboring point.
Dogs move toward the cage or sideways. They may move diagonally forward, but never back down.
Tiger Jumps
When a dog is right beside the tiger and the next point in that same line is empty, the tiger can choose to jump over and capture that dog; the tiger can also choose not to capture it, and instead step to a different empty point next to it.
A jump captures only the one dog it hops over, and jumps never chain into a second one.
Winning
The tiger wins by capturing 8 dogs or reaching the bottom row of the main board.
While the tiger is still in the cage, the dogs win the moment it has no move left that leads out — even if the tiger can still shuffle between empty points inside the cage. A tiger stuck outside the cage draws the game instead.
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.
