As a man, who played a lot in the real casinos, I will mention that the trump of the given gamble-resource is that probabilities of falling out  in roulette are maximally close to real ones. 

I can give examples are two hits of the ball to "zero" for 10 minutes of the game.

Playing roulette in Grand Casino, the online-casino I regularly win $15-30 in half an hour of a careful game.  I think that such a situation is a sign of an honest game of the network casino. 

To be fair, it is needed to say about omissions in the work of the resource from the point of view of an ordinary user.

Firstly, it is automatic grant of bonuses, without warning the player. 

Personally I consider it as couldn't-care-less attitude toward users and imposing unprofitable terms of winning back the bonus. 

Secondly, it is automatic writing off of the won facilities if the player refuses the receipt of bonuses in his profile.  When the won facilities were not shown out in time personally I supposed that I «got» to win back bonuses.
When refusing an option to charge bonuses in the profile I simply wanted not to get bonuses afterwards. 

However in no time they wrote off all the money which I won after the hidden and unasked charge of a bonus. 

In general, all above mentioned is a imperfection in the work of the site, which can embarrass players, counting on a permanent game on small stakes.

Further, Grand Casino does not have evident statistics of input-output of money from the player's deposit. 

For a long time I could not comprehend how much I won and output for a playing day.  The incomprehensible history of input-output of money simply makes me angry. 

It would be much clearer to do three columns - date/time, input (the sum) and output (the sum). 
The same disorder and mess in the part «History of games» – the time of stakes is incorrect, the history - incomplete.

In general, any contrivances are created to put a player in an unprofitable position which he cannot change in the hand mode, are not the things don't add points. 
Statistics plays guarantees winning of the casino as well, why to make the clients' position worse with tricks such as imposing bonuses and writing off money from the account?
Such a strategy is acceptable to small offices which count on a large rapid income from an unscrupulous game and does not imply a long-term presence in the market.
