There is no definitive answer to this question as it will largely depend on the type of bingo marker used and the conditions in which it is stored. However, most markers should be durable enough to last for several games, if not longer.
Some factors that could affect the lifespan of a bingo marker include how often it is used, how it is stored, and the type of ink used. If a marker is frequently being used and handled roughly, its ink may wear more quickly.
Conversely, if a marker is left unused for a long period of time, its ink may dry up and it may become difficult to use.
In general, it is safe to assume that bingo markers are relatively durable and will last for several games. However, if you notice any signs of wear or damage, be sure to replace your marker as soon as possible to ensure optimal play.
