The 25-Page Bingo Books are designed for use in a variety of gaming environments, including commercial bingo halls, charity fundraisers, and competitive bingo events. Each bingo book contains 90 numbered cards, with numbers ranging from 1 to 90, and each number appears exactly once on every card within the book. The books are available in two formats: 6up and 12up. To ensure easy identification and organization, the books follow a five-color rotation system (Green, Yellow, Orange, Blue, Pink). These books are part of the 12,000 series, providing traceability and compliance for regulated gaming events, especially those offering cash prizes.
