The 15-Page Bingo Books are designed for use in commercial bingo halls, fundraising events, and other gaming applications. These books feature 90 numbered bingo cards per book, with each number ranging from 1 to 90, and each number appearing once on every card within the book. The books are offered in two configurations: 6up and 12up, both following a 5-color rotation system (Green, Yellow, Orange, Blue, Pink) to ensure ease of identification and variety.
