When i get at least 0.75 cents, i play 0.25
spin and go which gives me 3 games. If you get lucky and spun a good multiplier (like at least 1$ pot) and get lucky again and winning that game, you gonna have a good start and can play micro cash/zoom games. Of course thats gonna be another story.
Me, when i get to build my BR to more than 1$, i then play the 1$ - 36 man hyper turbo KO games. If you are patient enough and get lucky (again
) and win that one, your BR can easily go up to at least 5$.
From there you can play cash/zoom games and triple your money, then you get greedy and start playing higher stakes games and before you know it, you already gave back the money that you've won....... then you go back to playing freerolls again....
That's the circle of life in freeroll poker.
