Goats and tigers. Three tigers hunt across a triangle of twenty-three points; fifteen goats try to pen them in. No dice — every move is yours.
The two sides
The tigers begin on the board, at the apex and the two points beneath it. The goats begin in hand. The goats move first, and the sides take turns.
The goats arrive
On each goat turn, set one goat down on any empty point. Until all fifteen are on the board, that is all a goat turn is: no goat may move while the herd is still arriving. Once the last is down, a goat turn is a step: one goat, one point along a line, onto an empty point.
The tigers hunt
A tiger steps one point along a line, or leaps: straight over a goat on the next point, along the same line, to the empty point beyond. The goat it leapt is taken. One leap per turn. The tigers win when they have taken five.
The pen
The goats win when no tiger can move — every neighbouring point held, every leap blocked. Fifteen goats can do it, but only if they arrive with a plan. A herd that itself cannot stir has been run to ground, and loses.
Once all goats are down, fifty moves eachwithout a goat taken is a draw.
