i cant complain, limbo has made me so much money lol, few months ago i put in 100 and cashed out 8k and yesterday i was showing my friend what i did and turned 20$ into 600 within like 30 minutes lol. I just play with the multi between 6x to 12x until i get a decent run (when you get a bunch of hits in a row and when I start to get big gaps in losses i switch the multi) this worked for me a decent ammount of times, also depends on the seed i think. I mean it is gambling so nothing is a sure thing.
Also I get to about 30$ and bet 25 cents, when i hit between 40$ to 45$ i switch to 50 cents if i drop lower then 40$ i go back to 25 cents, once i get to 55$ i switch to a dollar, once i hit 80 i switch to 2$, once i hit 130 i switch to 4$ and so on. Gotta play a lot with the multi but its worked for me plenty of times.
