Dice are actually more easier than any other luck based gambling games because you can set your winning chance at a higher percent though it can lessen your payout a little bit .
The winning amount doesnt also based on the games you play but it depend on the capital or to the bet that you will put .
@op , no theres no easy profitable strategy because all of them are the same . you can loose or win depending on how lucky you are
I personally believe however, that doing bets based on outcomes in sports or something like that is pretty close to being skill-related since you can study certain patterns that can potentially increase your chances of winning substantially.
Of course if you can bring a lot of traffic, referral is a no-brainer but i don't think that it is considered gambling more than in the sense you don't know how many results you will get and when.
