Two people go into the middle of the circle as everyone chants “Thunderdome! Thunderdome! Thunderdome!” The players are given a category (types of cake, makes of car, holiday destinations). They take turns to name something in the category. If they fail to come up with something, they leave the circle. Everyone chants ‘Thunderdome’ as a new player joins the winner. The category is changed and they play again. The winner stays on each time.
