IMO if you want to build your bankroll to move up a good option are the 1.50$, 3.50$ 9max Turbo and hyper sngs on stars.
They are really soft compared to zoom cash game, i tryed that out didnt play tournaments or sngs for 10 years, also i came back to poker like 1-2 years ago,
well its more like a tip, generating EV in those 9max turbo hyper sngs on 1.50 buy in or 3.50 is more easy than NL Foldem zoom cashgame i ended up playing 50 of those just trying it out noticing the player pool is fairly soft and weak. I ended up 40 $ +ev icm adjusted and 36 $ + for like 3-5 hours playing. And i didnt run that good or anything, its just the playerpool makes tons of mistakes.
And they are quite fun. Ofcourse you have to know what you are doing etc.... and variance might be quite high, but if i would build bankroll with 60-100 $ i would just spamm 1.50 sngs then move up to 3.50 sngs the hypers and turbo ones.
