The forces of evil are threatening to overrun Hogwarts castle in Harry Potter: Hogwarts Battle, a cooperative deck-building game, and it’s up to four students to ensure the safety of the school by defeating villains and consolidating their defenses. In the game, players take on the role of a Hogwarts student: Harry, Ron, Hermione or Neville, each with their own personal deck of cards that’s used to acquire resources.
By gaining influence, players add more cards to their deck in the form of iconic characters, spells, and magical items. Other cards allow them to regain health or fight against villains, keeping them from gaining power. The villains set back players with their attacks and Dark Arts. Only by working together will players be able to defeat all of the villains, securing the castle from the forces of evil.

If you are a fan of Harry Potter this is a great cooperative game and is another of my favorites. This base game has you play through 7 successive game adventures that increase with difficulty. As you progress through the games you will unlock new secrets and gain new abilities that will assist you on your journey to save Hogwarts from the Dark Lord.
This base game is for 2-4 players (increased to a maximum of 5 players with the Charms and Potions Expansion). Playing time varies depending on which of the seven game adventures you are playing through because the number of villains you need to defeat to win increases as you move up. It is recommended for players 11+ but my 7-year-old daughter played with us without too much trouble. This is a good game for kids that are a bit younger because it’s collaborative which makes it easy to help them. Since you either win together or you lose together it also encourages teamwork and you won’t have to worry about anybody being upset that they came in last place.
There are two expansions for this game, the Monster Box of Monsters expansion, which adds Luna Lovegood as a player option and adds four more adventures to the base game. The Charms and Potions expansion adds Ginny Weasley as a player option, allows the game to be played with a new maximum of 5 players, and adds another four adventures.
