发明名称 Instant bingo game card
摘要 The playability of an instant bingo game card or similar type game cards can be enhanced by providing for improved marking of numbers on a player card portion of the bingo card. In one approach, a space is provided along side each number in which a mark is printed and a scratch-off coating is applied over the mark. In a second approach, a microencapsulated pressure sensitive dye is applied over each number and by simply rubbing a particular number can be marked.
