By asking for 0.01 more
lol!
I played it myself, of course after a dozen free games of making it down to 2x, I put in 0.01, win up to 0.02, then lose both one cent games back to back on the first 'step' :| then I deposited 1 more cent, got to 4x and cashed out 0.04
I withdrew and stopped playing there. Made a 2 cent profit I guess
