Provably fair just means its not rigged.
Still 1% houseedge is quite high for an online casino.
thats your opinion and thats fair enough but you don'd mind if we don't agree. a good example is roulette
Reputed sites may not do these kind of hidden things because they know the potential of this online gambling business. If they can attract more people with honesty and good service then they can make really big money in normal ways without doing all these hidden things. But new sites may do these short cuts to get more money in faster ways, so chose carefully to gamble.
