No. As long as you are playing official lotteries, they won’t be rigged. Be wary of smaller lotto competitions where the results aren’t drawn on live television or live stream. When lottery officials regulate the draws, they are random and cannot be rigged. Lottery organizations profit from running the competitions since a percentage of all ticket sales go to the organization to continue operating. Lotteries also usually donate a portion of the profits to a well-known charity.
