[1] Each pack of Ace Trumps is based on a theme, such as cars, aircraft, animals or boats.
Each card in the pack shows a list of numerical data about the item.

That player then looks at their new topmost card, and chooses the category for the next round.
These include: Ace held some competitions, where cards were collected and then redeemed.
