This is a casino machinists. So they are using the game settings reduce the return to zero. And it is provable. This is simply seen in the games, as the return simply disappears. For all my requests, they sin on the game manufacturer and they say everything happens on his server, only a manufacturer like nettent sells games on his site only a demo game.

Это казино машейники. Так они пользуясь настройками игр сводят отдачу к нулю. И это доказуемо. Это просто видно по играм , как отдача просто исчезает. На все мои запросы они грешат на изготовителя игр и мол все происходит на его сервере, вот только такой производитель как неттент занимается продажами игр на его сайте только демо игры.

Please be informed that the casino is right in this case and it can’t influence the RTP (return to player) of the games. The game providers are responsible for running the games.
