Quick start
- The deer win by taking 7 dogs. The dogs win when the deer cannot move, or has been driven out of the grassland.

- While a dog is still in hand, place one dog on the grassland each turn.
快速上手
- 鹿吃掉 7 只犬，鹿赢。鹿走不动，或被赶出草原，犬赢。
- 鹿先走，每回合选一样：沿画好的线走一步到相邻空点；或者跳过紧挨的一只犬，落到后面的空点，把这只犬吃掉。
- 手里还有犬时，每回合先在草原放一只犬。
Rules
Board and Setup
The square in the middle is the grassland. The diamond above is the cliff.
The deer starts at the gate. A gate is an ordinary grassland point. Eight dogs ring the middle, and twelve dogs stay in hand.
Deer Move
The deer moves first, choosing one of two actions each turn: move one step along a drawn line to an empty neighboring point, or jump one dog beside it to the empty point beyond and take that dog.
Only one jump is allowed each turn — jumps never chain into a second one; a dog on the gate may be jumped when the usual condition is met.
Dogs Enter First
While a dog is still in hand, place one dog on the grassland each turn.
Until all twelve have entered, dogs already on the grassland cannot move. After that, a dog may move one step along a line.
Whether placing or moving, dogs stay within the grassland and cannot enter the cliff (the diamond) interior; the connecting gate remains an ordinary grassland point.
Winning
The deer win by taking 7 dogs.
The dogs win when the deer cannot move, or has been driven out of the grassland.
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
中间方格是草原，上面菱形是悬崖。
鹿站在门口。门口是普通草原棋点。8 只犬围着草原中间，12 只犬还在手里。
鹿怎么走
鹿先走，每回合选一样：沿画好的线走一步到相邻空点；或者跳过紧挨的一只犬，落到后面的空点，把这只犬吃掉。
一次只能跳一只，不能连续跳；门口上的犬满足条件时也能跳吃。
犬先上场
手里还有犬时，每回合先在草原放一只犬。
12 只都放完前，不能移动草原里的犬。放完后，犬才可以沿线走一步。
犬无论放子还是走子，都只能在草原范围内，不能进入悬崖（菱形）内部；相接的门口仍是普通草原棋点。
谁赢
鹿吃掉 7 只犬，鹿赢。
鹿走不动，或被赶出草原，犬赢。
计时
