where do we find that article?

the problem I see with changing such a loss rebate from a negative to a positive expectation is that there normally is such a huge house edge to overcome with slots

basing it on actual rather than theoretical losses would be a good start though

perhaps if we could read that article?

Once you have a player that has played a fair amount, I have no problems giving rebates for losses below the players theoretical. I usually do it as bounceback free play because you want to make sure the player comes back in and plays with it.
At my age, a "Life In Prison" sentence is not much of a deterrent.

I apologize, Funa, but I have trouble making heads or tails of that pdf file and I haven't even gotten to the math part. I am not qualified to begin with, but I thought if I asked for the details someone else more qualified could pick up on it.

If you can make sense of statements like these,

Quote:

the theoretical cost to the company will range from approximately the rebate percentage divided by twice the house advantage and would minimise at the rebate percentage. If the rebate on loss percentage were 10% and the house advantage 1.25%, then the theoretical cost of the rebate will range from roughly 400% of theoretical win at maximum, in an even chance game, and minimise at 10%.

then you are more qualified to answer your own question than I am. I know the meaning of each word in the above quote, but as a paragraph it just comes out as gibberish, as if the writer meant for it to be gibberish. But maybe that's just me. Apologies again. It's the sort of thing I'd have to dedicate an enormous amount of time to, in order to finally get less than 100% of the content out of it ... and that ain't happening

well, he gives a formula for up to 400% of theoretical loss [as max] if the house will go by actual losses - I can read. But "in an even chance game", what the ...? I guess he means 'even money' payoff. Perhaps eventually one could make sense of it, but life is too short to have to start parsing before you even get to the math.

Yeah I gave up as well.

I always thought loss rebate is something like: we rebate half your losses up to $200 (i.e. $100 rebate) in the form of free play once per day/week/month/year/life (depending on amount of action).

A loss rebate based on theoretical loss makes no sense. A 92% payback slot machine with a 50% loss rebate is a 96% payback slot machine. Just change the chip to do that (unless the whole loss rebate thing brings in more patrons, maybe that's why?)

A loss rebate on theoretical loss is precisely what free play is. You can’t get a loss rebate if you don’t lose.

I guess not.

But just to make it clear, a theo-based rebate is safe enough for the casino, while a loss rebate seems to be even safer, while it is not, allowing someone like Don Johnson to game his offers and take the house to the cleaners

no, that was not exactly right, although it is an easy and forgivable assumption to make, that the one thing is equivalent to the other.

APs actually do not like excessive discussion about this, so I will say I have made my case and shut up about it. It's not like it can't be looked up.
