Then again, it is not likely for you as a once a month gambler to actually feel the 0,5% house edge. This is something you notice after a lot of runs. If you only go once in a while, variance will take over and you may even end up winning or losing big.
People overestimate the effect of the house edge all the time. For example, just a couple of posts ago:
Thanks for putting it in numbers, always helps a ton!
So you always lose out, no matter the structure.
The house edge doesn't mean players always lose. It just means they will lose if they play too much, but it can take a very long time for it to happen.
On Just-Dice.com we have a 1% house edge, and take over a million bets per day, and yet over the last month the house had made a loss. The players, in aggregate, have been beating the house:
Here we see that over the last 6 weeks the site's profit has fallen slightly while the expected profit (1% of the amount wagered) has risen by 15,000 (CLAMS). In other words we have taken bets worth around 1.5 million CLAM (over $1.5 million), and the house edge hasn't "kicked in" at all.
Over the 6 months that the site has been running, on the other hand, the site has made a profit. That profit is 1.13% of all the coins that have been wagered, so it's running pretty close to expectation.
But over the last month the players have beaten the house edge, on a no-skill game, 1% house edge game.
