actually, i've tried it recently... practically the same mechanics and design as all the others
I would put it the other way around: other casinos use the same designs and mechanics as Bustabit/Bustadice.
Both casinos have been around for a long time and still have a very high daily waggered amounts (you can check them out at dicesites.com).
Also, very few casinos even offer the features that Bustabit and Bustadice offer, especially the native script support.
Exactly bustabit comes first don't exactly know if the very first one most of the other casinos just adopted it. You will rarely see new successful game mechanics in casino beside of the dice, crash and others.
Quoting an old post of mines to make a quick summary of who came first and when. Good old times
Is bustabit first crash game?
Yes, It was called moneypot when it was first announced and launched here back in 2014. Then it was rebranded to bustabit and in latter moment it was, as far as I understood, recoded and modified to bustabit 2.0.
and who invented crash game?
As far as I know user
espringe invented it; btw it's a pity he is not anymore around here on bitcoitalk.
