Players aim to reach the magical fragment at the end of the maze by placing cards between the paths.
When you shout "Ami Dungeon!", you place cards where you want to place them at the same time. If there is a conflict at this time, you will not be able to place your card where you want, so it is important to read your opponent's mind.
You can place cards of your own attribute wherever you want, but you can't place cards of other people's attributes unless they are in a place that is designated for cards of that attribute. Even if you don't get magic fragments, there are actions that allow you to increase the number of cards of your own attribute, so you can limit your opponent's actions and create opportunities.
