Just play one you feel drawn too and give it 10-15 spins then bounce to another if it isn’t hitting. There’s some games that I do great in or on one site ,but my friends on the same site or myself on a sister site can’t hit jack shit playing the same game. Also i tend to jump around the sister sites in the same manner. In terms of actual game to choose you really do just have to jump around and find ones you like that hit for you. Sometimes in games or just slot play in general you almost have to run it straight to the ground before it hits huge. Remember to factor in volatility not just rtp.
