Like in the main games, the purpose of the games has you capturing Pokémon. However, unlike the main series, this game has the capturing of Pokémon done via a different manner. Here, as you go through the various courses, various Pokémon will come out and challenge you. In order to defeat them, you have to type the text that is seen on the screen. You will later be marked upon the accuracy in which you have captured the Pokémon. Once the name of the Pokémon has been typed, they are caught in a Typing Ball.
There is a time limit in which you have to capture the Pokémon in, this limit varies depending on your skill level and the kind of Pokémon you are facing. Pokémon such as Pikachu have a long time limit to capture, while with the rare Pokémon such as Lapras you find have a very small time limit for you to capture them. The time limit helps determine the score in the course.
As you travel through the stages, you will sometimes encounter random letters appear on a bit of scenery. When you type these letters, they will turn into a coin with a letter on. As you reach the end of the level, if you have collected all the coins available, a special rare Pokémon will appear such as Lapras.
As stated previously, these rare Pokémon have a very small time limit in which to be captured so you need to type their names fast and accurately. However, you get rewarded with a large point score should you succeed in their capture.
Boss Pokémon work in an identical manner to the standard Pokémon and require you to simply type the name of the Pokémon you're battling in order to defeat them. However, first, they have a minigame where they throw attacks at you which you defeat by typing the characters shown on the attacks. After you have defeated the attacks, you then get to capturing the Pokémon. As usual, the score you achieve is dependent on the speed and accuracy in which you type.
