Pokémon Life might seem like an easy to understand game, but there are many different things happening during a game. This page has sections for everything concering the game. If you haven't played before I suggest you read every section to get an idea on how the game works. If you are an avid player and you get lost during a game and don't know how to continue, you can almost certainly find the solution here!
Many abilities and items can interfere with each other. It can be difficult to handle such situations. There is a webpage entry for every single Pokémon, Event, Victory and Item card in the game, so be sure to check them out! Common and rare interferences and how to handle them are explained on the card's webpage.
