I'm not sure how to do the same query on roobet (although wouldn't be overly hard to compute manually), but roobet has a significantly higher house edge (i.e. more reds) which would be negated by the fact they have not been running nearly as long (i.e. less likely to have had freak events), so I'd guess the longest red streak is pretty similar
Hello RHavar
Few weeks ago I tried to compute the Roobet house edge and I found 4%.
Do you think my calculations are right?

Just because Roobet is growing successfully, that doesn't mean it is a pioneer of Bitcoin Gambling Industry! Stop believing gambling sites blindly. Here's the proof that Roobet's crash game is based on the same algorithm (taken right from the 'Fairness' page of Roobet):



Do you see a red box? Can you read the formula inside? Isn't it same to the one in OP?

Don't think that I will write random things anywhere on forum without any knowledge. If I was sure enough to include that line in OP, it does mean that I am sure about the fact. Period!

You're right it's the v1 version
https://github.com/Dexon95/Bustabit/blob/master/gameserver/server/lib.js

But in this version the house edge is computed like that as far as I understand :

  // In 1 of 101 games the game crashes instantly.
    if (divisible(hash, 101))
        return 0;


    // Use the most significant 52-bit from the hash to calculate the crash point
    var h = parseInt(hash.slice(0,52/4),16);
    var e = Math.pow(2,52);

    return Math.floor((100 * e - h) / (e - h));


While in the Roobet version, 101 has been replaced by 25.
It means there is an instant crash every 25 game rounds, ie 4 times out of 100.
So we can assume the house edge is at 4% on Roobet...  Undecided
