I too was a novice online casino player in India and I want to share my experience. When I was first reading, I often wondered whether it was better to start with cash or virtual games. My advice: start with a demo game. This will help you get the hang of it and understand the rules without risking your budget.
Regarding bonuses, my advice is this: don't get hung up on bonuses. Often in order to get winnings with bonus status, you need to be compliant. So before you accept a bonus offer, study the terms and conditions carefully.
If you want to get closer to more slot machines, slots, cards, roulette, my advice is this: learn about the RTP (return to player) in each game that has a higher figure. It is also worth keeping an eye on the calculation of bets and their costs according to your budget.
In conclusion, I want to say that playing at online casinos can be fun and profitable if you approach it with common sense.
