It is still called "giveaway" I think when you get something in return of you gambling isn't it? I do not know what those are specifically called. Normally what you do in a casino, let's say specifically dice, you go there, pick an odd, gamble, win or lose, and get out. When you get something extra for anything else? That is called something, I assumed it was called giveaway, it could be rakeback in other situations but this is not rake so I am not entirely sure what it would be called.
Long story short what I meant was getting anything returned instead of just pure gambling is a marvelous thing, stake should keep that up, it is always nice to get extra back when you are gambling, it makes that %1 house edge lower because you are getting something in return, doesn't make it profitable but makes it at least a bit more fair grounds to gamble.
It's all a blurry line these days. Giveaways to me tend to be gifts with very little effort, or with equal chance of winning to all players. So number hunting, result hunting, regardless of bankroll, not wager contests, would qualify.
Rakebacks, cashbacks, edge back, those aren't giveaways, they're features:)
