A bunch of special stages have arrived on Pokémon Shuffle this week. First, to celebrate 5 million downloads of Pokémon Shuffle Mobile, a Mewtwo stage has begun. This special stage has no item cost and will run until January 19th, 2016. For those on the mobile version, there is no stage and you are simply given Mewtwo without having to challenge a stage. [Thanks, Serebii.]
Another legendary Pokémon appears this week in the form of Regigigas. In this stage, Regigigas will be easier to catch if you have Regirock, Registeel, and Regice on your team. This stage will be available until December 28th, 2015.
Next, a Regirock stage makes its return to both versions of Pokémon Shuffle. The Regirock stage will run until December 18th, then will be followed by Registeel from December 18th to the 22nd, then finally that will be followed by Registeel from December 22nd to the 28th.
Lastly, The Mega Garchomp stage makes a return to the 3DS and its debut on the mobile versions of the game. Those who make the top 12,000 players in Europe, 18,000 in North America and 50,000 in Japan will receive a Garchompite.
Pokémon Shuffle is available for Android, iPhone, and Nintendo 3DS.
