I think there is no such term as played correctly in dice games. The only reason why you are in profit is because you got lucky that time. When you lose, don't ever think that you played the technique in a wrong way. It was only a basic technique so I see no reason why we can't follow it properly. Just accept your defeat and don't try to complicate things anymore.

I guess the technique that you are using there is popularly called as martingale because martingale also involves doubling bets by the time the previous bets are a loss. When I was a newbie in dice I was very active on using this but later on I switch on betting the default way.
