I quit the game when I won as much as I wanted, and if more - I quit immediately 
Wait so when do you exactly quit lol, you saying when you win some game you stop gambling but you are also saying if you win more you again quit. So what are you even doing exactly do you set a goal and when you achieve it you quit gambling or play beyond your goal and then quit lolI think what he means is like this: he has a winning target lets say $100, but at the process he might won more than $100. Like if we play in a slot game, it is possible to win big amount unexpectedly. Just an example, at the beginning he has won $50 out of $100 (target) after he got $50 then Imhe got really nice win in a single bet that makes him won $200 in total (Obviously he will stop in this situation). On other hand, if there is no big win but he got continuous winning streak till he reach $100 profut then he will stop as well. In other words, he will stop depends on the situation.
