During today's Nintendo Direct, it was announced that new game called Pokémon Shuffle is to be released for Nintedo 3DS and 2DS. This game is a puzzle game similar to Pokémon Battle Trozei and has you have to shuffle tiles and level up characters in order to capture Pokémon. In each battle, you have 4 Pokémon to choose from, and you need to think of your type advantages. There is no time limit, so you can take as long as you like to study the board. To clear each stage, you'll have to reduce the HP of the wild Pokémon you face to zero within a set number of moves. It also features Mega Evolutions which are used to clear the board quicker.
You have a 10 minute wait between battles if you lose, but you can get in there earlier by paying or using items that have been acquired through gameplay. You can also pay for various items to aid in your gameplay. It is due for release in February 2015 and is free to play but with payments included.
