The Battle Guide is a guide that appears in Mario & Luigi: Paper Jam, Mario & Luigi: Superstar Saga + Bowser's Minions, and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It gives the player information on how to perform Battle Basics and Battle Actions, such as Jump, Hammer, and Bros. Attacks. The Battle Guide also includes a demo on how each action is performed, and allows the player to practice the action themselves without spending any BP. Anything not yet viewed will have a "!" displayed next to it.
In the former two games, it can be accessed by tapping an icon in the bottom right of the touch screen during battle. In the latter game, the guide is accessed by hitting a Command Block known as the Guide Block.
