My answer is that they should start asking the person questions concerning the type of things they like normally. Aside from wanting to gamble, which type of game do they like? Are they fully into sports, or do they just like any gaming? My recommendation will be based on the information I get from them, because it's not entirely easy to start sports betting when you know nothing about sports, as it will give you a tough time with the whole process. Slot games, on the other hand, have much lower winning chances compared to games that require skill.
