There is no specific answer to this question as it depends on the jurisdiction in which you reside. Generally speaking though, playing Bingo online is not considered an illegal activity.
In some jurisdictions, such as in the United States, playing Bingo online is considered a form of gambling which is regulated by the state. However, in other countries, such as in the United Kingdom, playing Bingo online is not considered to be a form of gambling and therefore does not fall under the jurisdiction of the state.
Ultimately, it depends on the jurisdiction in which you reside and whether or not playing Bingo online is considered a form of gambling. If you reside in a jurisdiction where playing Bingo online is not considered to be a form of gambling, then you should not have any problems playing the game.
However, if you reside in a jurisdiction where playing Bingo online is considered to be a form of gambling, then you should be aware that you may be breaking the law.
