It's just testing for luck.
Because is all-in betting, so it purely depends on luck. It's called hot streak section, you keep betting until you lose. Most of people are stoped while on certain profit, but for me keep going until lose the streak win.
Doing all-in betting is good with free money (5-15$) because you can cashout big while hitting 3rd-5rd.
I rarely do that, in fact I do the opposite a lot more. Like let’s say I have 100 bucks deposited, whatever the tiniest amount I could wager, that’s what I wager, if I can find 1 cent per bet type of deal then I will wager just 1 cent, that means I will be able to wager 10 thousand times even if I lose it all, and of course you don't lose it all which means that I get to wager tens of thousands of time.
With this method you both increase the amount you wager because in the end you will not lose it all that quickly and that means you wager a lot in the end, and also it doesn't end that quickly because I want to have fun and being done after just 5 bets is too quick and doesn't feel too much fun.
