Since there are 14 official languages in India, the casinos are not able to offer gaming in everyone's first language. The most spoken languages in India are Hindi and English. Almost every online casino offers their website in English.
Unfortunately, there are not many reputable online casinos with a website in Hindi. You have more options when choosing an English casino. When contacting the casino support, you may have to ask your query in English,. as support representatives may not speak Hindi or another Indian language.
