The 50 Bundle Bingo Books are perfect for smaller bingo events, offering a convenient and cost-effective solution for games with fewer participants. These books come in a variety of configurations (5, 10, 15, 20, or 25 pages per book) and follow a 5-color rotation (Green, Yellow, Orange, Blue, and Pink) to help organizers quickly distinguish between books. Each book is printed with 90 numbers ranging from 1 to 90, with each number appearing only once per card, ensuring that every bingo card is unique and ready for play.
