A couple of years ago ! built $50 up to $600 playing Spin n Go, mainly due to winning $500 in a $15 one off gamble when I had lost a few and was drunk, I was down to $15 and put it all on a Spin n Go and won.
I foolishly kept on playing $15 games and was soon down to $100 at which point i went back to proper poker.
Spin n Go's are really the poker equivalent of bingo, a terrible game for, mainly, terrible players.
