It’s rare for me to play on a casino with a domain using a country like “.ru”. Are you sure that your casino will mot be limited to Russian citizen since the country have a sanction on multiple country which you might find restrictive when you accept players from country that sanction it.
If your platform is a country-based extension that only means that you cater to that country and checking your website I see that it is because there is no embedded translator to translate the website content, I don't know the purpose of creating an announcement on an English-dedicated forum like Bitcointalk if there is no way to understand what's on the platform, I would not play on a platform that I cannot understand
The default language is in Russian which I’m not where is the translation button for your casino. I really suggest to have a mirror link for global players so that it can be easily play or browse on your games that is on default RU players.
If he wants players from other countries he should create a mirror site specifically for global players, there's so many questions that OP needs to address, we will see if he will take our advice and follow these pieces of advice.
