Quick Question on House Edge Percentage

Hello all fellow CCers,

I do apologize for what may be a novice question, but can anyone help me out as I am having trouble understanding sims:

If a sim shows that the casino edge is -0.37%, does that mean the house edge is negative and I should run to play there, or that my edge is negative?

Just a little mixed up!

Thanks everyone in advance.

House edge is a house edge

Welcome, clouds.

A casino edge of -0.37% means that the players are at a disadvantage of .0037 and will average a loss of $0.37 per $100 wagered using the optimum basic strategy for that game in the LONG run. There are games today that come close even but none that I know of that have a player edge off the top. In the good old days, there were some games that had a player advantage off the top because of the rules offered.

Of course, the house edge changes after the first card is dealt. When enough small value cards are dealt in proportion to large value cards, the edge shifts to the advantage of the player(s). That is why card counting exists.

Good luck and take your time to fully learn counting and all that goes with it before you ever place your first bet. Others here will echo that card counting is not a method to get rich quick.

If the house edge is negative, the player advantage is positive, meaning a negative house edge is a positive expectation game off the top.

That doesn't mean the house edge is being represented correctly by your simulation though.

It depends on what sim you're looking at, but you're right that -0.37% can refer to a positive player's edge or a negative player's edge.

Having a positive player's edge is rare, so it's more likely that the sim is confused and presenting a player's edge of -0.37% (a house edge of +0.37%) rather than there being a house edge of -0.37% (a player's edge of +0.37%).

I guess it does depend on the sim and how it expresses the edge, but the strategy engine here expresses a house edge in the negative when the player has an advantage.

For instance, it shows:

1 deck, S17, DAS, Early Surrender, Peek
Estimated casino edge for these rules: -0.77 %

8 decks, S17, DAS, No Surrender, Peek
Estimated casino edge for these rules: 0.47 %

Reread your post

clouds:

I reread your post and see that what I read early this morning is not what I am reading while I am awake. As others have correctly pointed out, a house edge of -0.37% translates to a player edge of +0.37% but that house edge is based on the parameters of the game that you put into the sim. If you correctly input the parameters of the game and you in fact found a game that exists with a player advantage, spend every waking hour in that casino because it won't last long.

Oh, and pm me the location while you're at it!

However if you use a simulator like CVCX, the -ve sign means that YOU are at a disadvantage. It is the OPPOSITE of a basic strategy house edge calculator.

New too. But how do you calculate the house edge? I know it should be negative for players; casinos need it. Who calculated all those numbers -0.37% or other -% you can see in replies? All i could see is all kinds of percentages and nobody tells how they cameup with the numbers!!! That -0.37% means I lose about 4 bux if i buy 100 bux in chips. Most honest players will tell you that they lose 100 automatically!!! Less than one hour!!!

Welcome aboard,

The house edge (or house advantage) is the negative of the player's expectation value commonly known as ev. So technicaly speaking when you say -0.37% house edge that means the player has +ev of +o.37%

The expectation value is the average[/U] amount lost or won (here expressed as a percent) of the TOTAL of your bets after playing so many hands (hundreds of thousands).

The ev can be calculated using combinatorial analysis: all possible hands are dealt and after deriving the optimal playing strategy (commonly known as basic strategy) the expectation value is calculated.

The house edge is not always positive, some stores have an off the top edge, you got to keep your eyes open
