Hi Prestige,
Great, thanks for the interest and compliment!
It would be legal to promote online anywhere in the world, we have affiliates from all over the globe.
In terms of PPC though it would be a different story! I know Google for instance does not allow any lottery related adverts on their adwords, although having said that many affiliates and companies seem somehow to circumvent this. I see Google Ads with lottery content running all over the show.
So I am not sure how seriously this is taken by Google.
In terms of promoting offline, I believe as long as you are not selling physical lottery tickets offline you are OK. Most countries have laws prohibiting the operation of private lotteries offline. As mentioned in my first post though, you would merely be promoting a delivery service so you would not be contravening any laws I know about.
Please feel free to contact me on [email protected] for further queries or concerns.
Best regards
