I am not lottery or sweepstakes legal expert. However, I do understand what a lottery is. From what I’ve seen of how drakemall.com works, it is highly likely that this site could be considered an illegal form of instant lottery if played within the United States. I should point out that this business claims to operate from within Estonia. In answer to your question, if you live within the U.S., this site may not be safe to use. You will need to read up on your state, city and county laws for what is considered illegal gambling.
