There is no definite answer when it comes to legality of hosting an online bingo game. In theory, it could be considered a form of gambling, which is illegal in most countries.
However, there are a few loopholes that could potentially allow this type of game to be hosted without breaking any lAWS.
For example, if the bingo game is played for charity purposes, then it may not be considered gambling and could therefore be legal. Additionally, if all money awarded in prizes goes directly to the players and not to the organizers or sponsors, then it may not be considered gambling either.
Ultimately, it is up to the jurisdiction in which you reside to decide whether or not hosting an online bingo game is legal. If you’re unsure about any aspects of hosting an online game, then it’s best to consult with an attorney before starting anything up.
