I've played both Aviator and JetX. Honestly, I liked JetX much more. Firstly, the game is from Smartsoft — it's made wisely. The interface is very simple, everything is intuitive: two betting fields, auto-bet, auto-withdrawal, history of multipliers — convenient even on a small screen. You play calmly, you don't have to click all the time. I especially like that you can place two bets at the same time: one for a safe withdrawal, the second one to take a risk. And most importantly, the RTP is high and you can really raise it, starting with minimum bets from ₹1. Plus, there is a demo mode to try. If you want to understand in more detail, look here:
jetx bet - there is all the information on the game, and you can try it yourself. In my opinion, this is one of the best crash projects today.
