Spectacular wizards like Albus Dumbledore, Severus Snape, or Lord Voldemort compete in the categories of First Year at Hogwarts, Wand Length, Family Tree, Fear Factor, and Top Trumps Factor to outdo each other. In Top Trumps Harry Potter, there are 30 witches and wizards featured on 30 cards with cool designs, clever statistics, and exciting background information about the 30 most impressive wizards from the Harry Potter series, some of which you may not even know. That's the essence of Top Trumps: all players receive an equal number of cards, and then they compete against each other. This means that whoever has the highest value wins the round and takes the top cards from their opponents, adding them to their own stack. The player who ends up with all the cards wins.
