Zynga has announced that its match-3 mobile game, “Harry Potter: Puzzles & Spells,” is marking its one-year anniversary with a full week of festivities.  

The seven-day celebration includes in-game gifts, events, sweepstakes and new content.  

“We’re incredibly proud of the accolades and reception that ‘Harry Potter: Puzzles & Spells’ has received, but we’re even more inspired and humbled by the players who have joined us on this journey,” says Yaron Leyvand, executive vice president, games, Zynga. “We’re thrilled to celebrate this milestone with the fans, and look forward to opening the game’s next chapter, together.” 

From Sept. 22 through 24, players who log in to the game will be treated to a daily in-game anniversary gift. Inspired by Dudley Dursley’s birthday, a new London Zoo-themed event in the game will invite players to collect “presents” on their gameboard to earn reward chests. Players can make matches next to mysterious boxes on their gameboard to release the python inside. Starting Sept. 23, players can join in a Hogwarts tradition with the in-game House Pride Event, completing puzzles to earn points for their house with results tracked in a global leaderboard. 

Throughout the anniversary week, visitors to “Harry Potter: Puzzles & Spells” on Twitter, Facebook and Instagram channels will be invited to post memories from the game tagged #PuzzlesAndSpellsAnniversary. Three players will be chosen at random to win an anniversary prize package, packed with in-game currency, items, power-up bundles and more.
