Three for a pig is a car game, an alternative to pub cricket for the open countryside.

Two players are given a side of the road, left or right. The aim is to score 100 points for animals on your side with these rules:

• three for a pig
• minus ten for a horse
• cat looking out of the window is 100

and otherwise animals score one point. The usual rules include these points:

• you only count animals beyond the carriageway on your side;
• estimate for flocks of sheep and so on;
• humans, birds and other non-mammals don't count;
• scores never drop below zero under the horse rule.
