wrong alt you were fully supporting PD 3 posts upper.

As a matter of fact, quite a few dice sites are having a house edge of <1%, and they work fine. Safedice for example has a 0.5% house edge except for very large bet and Crypto-Games has a house edge of 0.8%. Betking and Betterbets have cashback programs which bring the effective house edge to below 1% as well.

voted for primedice as the rewards are good although fortunejack is good with a fast server and good selection of games so that would be 2nd preference

The 1.15 mil CLAM shown on JD is the total onsite investment. Investors could useoffsite in the chat to declare some offsite investment. JD actually has the max profit as 0.5% of the total effective bankroll. For details of this, you may refer to the FAQ on JD.

The 0.5% is how JD determines the max profit per bet based on the total effective bankroll (both onsite and offsite). Let me try to explain it with a simple example.
Suppose I invest 100 CLAM in JD, the JD bankroll will increase by 100 CLAM and the max profit will increase by 100*0.5% = 0.5 CLAM. That 0.5 CLAM is how much I can lose at most in one bet to the JD players. Now suppose I love taking more risk, and I enter "/offsite 900" in the chat to declare a 900 CLAM offsite investment (this can be done even though I have no more CLAM in my personal wallet), the site total effective bankroll will increase by 1000 CLAM (100 onsite + 900 offsite). The max profit will increase by 5 CLAM, which is how much I can now lose at most in one bet. So now I am actually risking 5% at most per roll instead of 0.5%, but still the max profit is 0.5% of my total declared investment.

and if you wanna test something out or just for fun,  you can use dash-dice.com to kill your time

That's pretty much exactly right.

My only small criticism would be that when you "/offsite 900", the max profit increases by a further 4.5 CLAMs (not 5) since it already increased by 0.5 when you invested the first 100 CLAMs. You are correct that you would then be risking up to 5 CLAMs per roll however.

Just-Dice.com ofc!

No not 999, heard some bad stories about that one.
