The answer to this question is difficult to determine as the length of time that a particular Mecca Bingo game will run can vary greatly. However, according to some reports, a standard Mecca Bingo game typically lasts for around two hours. This means that if you are playing at one of the popular venues, chances are that the game will be finished around half past midnight. If you are playing at one of the smaller venues, however, the game may only last for around 30 minutes or so.
So, overall, it is hard to predict how long a particular Mecca Bingo game will last. However, based on these reports, it is safe to say that a typical game will last for around two hours.
