I like the clean design and the concept of using block hash as random number. Do some promotion. This game gotta be popular.

Yes. You are correct if you are betting on only one digit. You can bet on multiple digits at a time and thereby have more chance to win.

Anyone tried this so far?

I like your site, but now i m not ready to play it, because i have save my bitcoins your halving, actually within week i have lost so in this time i don't want to touch it, but i give you guaranty that after halving i definitely play it, it is easy to understand how to play it, also no need to registration, so no problem for me or others.    

I love your site, the whole site is quite interesting. It's just the lack of support for doing a communication against the owners in the event of a problem. And the lack of features that can be used to interact against a fellow player/owner of the site. I hope it can be added for convenience all players

Your calculation seems to be wrong. While we say a dice site having 1% house edge, does it mean that player has 99% chance to win? No. It means the players has 49% chance to win. Similarly, here, if they make it 8x return, that would mean, they are running on 0% house edge. Your demand of 15x return is absurd, as it would mean -ve house edge, i.e. house is certain to lose in the long run. 4x return is 25% house edge, with the chance of 400% return.

I myself played their PvP game. They dont have many players playing right now. But, the game is working perfectly, with the advantage that u get back your bet amount, if everyone has lost in a round. Rules seems to be pretty clear to me. U might like to read the FAQ.

Quite a good concept and this is totally based out of luck and provably fair! However what I find lacking is,players should be able to select a block manually like they can decide which block they wish to bet on,depending on the last digit of that has,they can put their guesses.Anyhow playing against the house is good to since you're paying out 4x.Trying my first bet as a type!

Thanks for pointing out the difference between house edge and expected value.

What are the EVs of established Dice sites?

Gambling is not charity. People are expected to lose as well as multiply their wealth. It is part of the game.

You did not consider the fact that, unlike dice sites, you can bet on multiple options at a time here and thereby significantly raise your chance of win.

My calculations are definitely correct.

What is House Edge?
The difference between expected value and 100%.

For example:

I say that you can flip a coin. If it is heads, you gain 1.5x profit, if it is tails you lose it all.
Expected value = 50%*1.5x + 50%*0 = 75%
So the house edge is 100%-75% = 25%

Why does this game have a house edge of 75%?

One in 16 games gives you 4x the money.

So Expected Value = 1/16*4 = 4/16=25%
Hence, house edge = 100-25=75%


That changes nothing. Let's say you bet 1 BTC spread across 5 different options. (0.2 BTC on each option)
The expected value (average winnings) is 5/16 chance to win * 0.8 amount won = 0.25 BTC

What if you had normally bet just 1 BTC on 1 single option?
1/16 chance to win * 4 BTC amount won = 0.25 BTC expected value

The expected value in both cases is 25% (0.25 BTC 1 BTC) and hence the house edge is 100% - 25% = 75%

Great. Just placed a bet of 0.005 BTC on 7.
