In Sega's new anime strategy, Revolve8, you'll be opening up plenty of books in order to get what you need to power up your heroes.

Yep, the books are basically loot boxes. And that means you need ways to get as many as you can without paying a penny, right? Exactly, that's why we're here.

We're breaking down all the ways you can earn books. There are timers, rewards, free and of course paid books to look through, and each of them can be available to you without having to spend any of your own money, of course.

In order to get the valuable materials you need to power up your heroes and keep them ready to plough through the most fearsome of opponents, you'll need to open as many books as possible. The game gives a bunch to you, but you'll have to work for them.

Read on for all the essential information on how to get books in Revolve8, and while you're here, take a look at our full list of Revolve8 heroes and cards.

League books

The first thing you should know about books is that the contents of each book will differ greatly based on your league. The higher the league you're in, the better the contents of books.

In fact, many heroes and cards will be unavailable to you until you manage to rise through the leagues, and even books in the shop will become available to purchase as you progress.

From each league match you win, you'll get a book to open on a timer. Early on you'll get books that open in five minutes, but it won't be long until it takes more like eight hours to open a single book, and more than that.

Open the quick books first, and make sure to load up a long timer book before you log off for the night.
