Pokémon Shuffle is a free-to-play puzzle game developed by The Pokémon Company (the same guys responsible for the Pokemon RPGs on the Game Boy) and is the first Pokémon game to be released on Android outside of Japan.
It’s a match-three game in the same vein as Candy Crush Saga, but each stage plays out as a battle with a Pokémon. If you complete the level, you’ll have a chance to catch the Pokémon you faced. Your chances of catching them will be better or worse depending on how you performed in the battle.
If you finished the stage with three moves left, for example, these will be converted to points and added to your score, increasing your chances of snagging the Pokémon. It’s a neat idea because it encourages you to play smarter and be more strategic.
