yes it is possible, just keep practicing, you will get there !

I have limited access too. It forces you to really improve on the three games that you have available.

thanks Guillem

Yes, it is certainly possible. I signed up December 19 and played a couple games just to see what it was about. Seeing the 30% off sale ending with the year, I started playing a lot from December 25 onwards to see if this was something I wanted to pay for. I broke SPI 100,000 December 31 with access only to Peak Master, DB King, and Pan Girl. At that point I decided to go Pro before the sale ended, and I am SPI of 500,000 now. Having additional games to play definitely helps boost your SPI; however, if your ears are no good all your game scores will be low regardless, which will be mirrored in your SPI. I wish there was a way to manually set my level in the games; I've spent a lot of time "breezing through" certain games to "level up" to my actual level where work can really be done.

I did 1.3 m spi without full access, after this i did challenge from 0 to golden ears and it took 2 hours 30 minutes (on new profile) just with starting 3 games, so push man and you will make it)
