This week, both the mobile and Nintendo 3DS versions of Pokémon Shuffle are being updated with a few new challenges. [Thanks, Serebii.]

First off, Mega Sceptile appears as a Competitive Stage which will run until April 12th. This also marks the first use of Fast Match in the 3DS version, meaning you get additional points if you make a match quickly after your last match. The top 20,000 in the US, 12,000 in Europe, 50,000 in Japan and 80,000 on Shuffle Mobile will receive a Sceptilite.

A Tornadus Incarnate Forme stage has also begun this week and can be only once per day, though the odds of catching the Pokémon increase with each day.

Finally, Groudon makes a return to both versions, while Emboar begins its repeat run on the 3DS and its debut on the mobile version. Both of these stages will be available until April 19th.

Pokémon Shuffle is available for the Nintendo 3DS, iOS and Android devices.
