Aviator is a great alternative to simple slots. Here, you decide when to withdraw your bet. Watch the plane fly higher and higher and try to guess how high it will go. The longer the game lasts, the higher the bet multiplier. Once the plane flies away, taking your bet with it, the round ends. The game has a high RTP of 97% and offers a virtually unlimited multiplier.
You can start gambling by claiming the 125% welcome bonus from Mostbet. The best tactics, though, would be to start with demo mode and learn simple rules.
