What exactly were the accusations?  They have so many players that there's absolutely no reason to cheat.  People are silly.

I've heard from a few different people that csgocrash.com (who I regretfully sold a copy of the source code of bustabit, for 2 btc) has started scamming from its users. I have no way of verifying the accusations, but would strongly advise staying clear of that site until it's resolved.

Wow! Our biggest single-game win ever. A big congratulations to alexy, winning a 35.3 BTC in a single game (with a bet of 0.03 BTC or 30000 bits)!

Let's see how long we can hold this place!  


_{Edit: Maybe I'm celebrating a little too early. Seems like thebitcoinstrip.com has had some stats collection errors in the past week, and is clearly underestimating PD wagers? (it shows only 224k BTC wagered?)}

I give up playing bustabit. .1 Bitcoin I just disappear. I can not control my appetite when you're getting profit

It would look very similar, just with different calculations for the crash point.

What would the code look like if you wanted a set house edge which is not scaling?

That's the only really interesting line. We can ignore the "0x crash 1-in-101 games" part, because that is only used to fund the 1% bonus that it paid out on the other 100-in-101 games. It has no effect on the house edge at all.

We can even lose the Math.floor bit, because that just makes sure the result has no more than 2 decimal places. And divide the top by 100, because that function is returning the crash point times 100 (so it's an integer).

So the crash point is simply:


e is a big number, but it doesn't really matter what it is (it's 2^52)
h is a random number between 0 and e-1 inclusive

Let's look at three cases:

1. If h is at its minimum, 0, the crash point is 1x

The house edge is 0%. (We can ignore the 1-in-101 0x crashes, because on the other 100-in-101 games we get a 1% bonus, assuming we're the only player, or that all the other players are also playing at a 1x cashout).

2. If h is half way through its range, e/2, the crash point is 1.99x

So we have a 50% chance of winning 1.99x. That gives an RTP of 50%*1.99 = 99.5% and so a house edge of 0.5%

3. If h is at its maximum, e-1, the crash point is 0.99e+0.01 (ie. very high, since e is a big number)

So we have a 100/e% chance of winning 0.99e+0.01. That gives an RTP of (99e+1)/e% ~= 99% and so a house edge of a tiny bit under 1%.

So you can see that the house edge ranges from 0% to 1% as your payout multiplier ranges from 1x to high numbers.


The payout multiplier for any particular h is (from the code you pasted):
  m = (e - h/100) / (e-h)   [1]
and the probability p of hitting that payout is:
  p = (e-h)/e   [2]
  h = e-ep
the RTP for that h is [1]*[2]*100:
  (e - h/100) / (e-h) * (e-h)/e * 100
  = (e - h/100) * 100/e
  = 100 - h/e
and so the house edge is simply:
  edge = 100 - RTP
  = h/e
  = (e-ep)/e
  = 1-p

Now you want the house edge for a given multiplier, m. Let's find h in terms of m:
  m = (e - h/100) / (e-h)
  (e-h)m = e - h/100
  em - hm = e - h/100
  em - e = hm - h/100
  e(m-1) = h(m-0.01)
  h = e(m-1)/(m-0.01)

And so the house edge:
  edge = h/e
  = e(m-1)/(m-0.01)
  = (m-1)/(m-0.01)

And there's your answer. The house edge for a probability of p is 1-p, and for a multiplier of m is (m-1)/(m-0.01)

Examples:

  the house edge when you have a 0.5 probability of winning is 1 - p = 1-0.5 = 0.5%
  the house edge for a multiplier of 2x is (m-1)/(m-0.01) = (2-1)/(2-0.01) = 0.50251256%

Edit: if all you want to do is change the house edge so that it goes from 0% to N% instead of 0% to 1%, I think you only need to replace the 100 in the Math.floor line by 100/N. Don't change the insta-crash logic unless you want to unbalance the bonus system. Looks like you already changed it to insta-crash every 51 games (without changing the corresponding comment), but that's a bad idea. People won't want to play a game that insta-crashes so often. Adjust the edge using the Math.floor line instead.

Example:

>>> e = 2**52
>>> h = e * 0.75
>>> 100 - (e - h/100) / (e-h) * 25 # the bustabit setting - house edge is 0.75% when we have 25% chance of winning
0.75
>>> 100 - (e - h/20) / (e-h) * 25 # increase the house edge by a factor of 5 - house edge is 3.75% when we have 25% chance of winning
3.75

This program is my betting site. I learn it in my groupmates in fb. It is an easy betting site but for me its not easy to win. I have pattern but its not applicable always because I lose game in just one shot. So I decided to quit and go to satoshimine where I lucky to this gambling site. I mean always win. He he.

Wow, ok, thanks for catching me up on that.  I, personally, find it absolutely nuts to adopt an already in-use unit and apply it to bitcoin.  I think that everyone knows what a bit is, it's a unit of information.  Ie a 1 or 0 in a computer memory.  It's a true or false.  To me, the idea of saying that 100satoshi is 1"bit" is a little like saying, let's say that 100 satoshi's = 1meter.  How that is suppose to alleviate confusion, I have no idea.

Anyway, nothing personal, but I certainly won't be following this trend.  If for somereason, microBTC is too abstruse, what's hard about 200satoshis?

Sorry if I derailed your thread about the social platform gambling.

Those bots are probably really hard to code though, and no one who has a +EV bot has shared it/sold it AFAIK.
