How does the pages raffle system work?
Here we will look into how to acquire pages for your books and how they are drawn at random.
You can earn pages by purchasing Packs - Seasonal, Classic, Rare and Epic - or by being rewarded Boxes - Classic or Seasonal - after completing puzzles in specific game modes that in the older version of the library, rewarded you books. If you don't have an active collection, Packs and Boxes offers will not appear.
The logic and probability behind what kind of pages (rarity) you will earn is different for packs and boxes. Check out the details for each of them below.
Packs
Each pack is drawn from just one of your active collections, chosen at random per pack. Each pack’s pages are split among up to 3 books within that collection. The chance for each page (except guarantee in Ultimate) depends on how many Common, Rare, and Epic books are in that collection:
- Epic:
(Number of Epic Books ÷ Total Books in Collection) × 0.93 - Rare:
(Number of Rare Books ÷ Total) × 0.98 - Common:
1 - Epic - Rare
Example 1: A collection with 5 common, 2 rare, 1 epic books (8 total):
- Epic: 11.63%/ Rare: 24.50% / Common: 63.87%
Example 2: A collection with 3 common, 2 rare, 1epic books (6 total):
- Epic: 15.50% / Rare: 32.67% / Common: 51.83%
- Special for Ultimate Packs: You are always GUARANTEED at least 1 Rare & 1 Epic page. If a collection doesn't have Epic books then we will reward 2 Rares.
- Finished Books: If you get a page for a finished book, it goes to your Extra Pages Bar which can net bonus Bitz rewards once it is full.
