When a gambler waits until the game ends, of course this will be very exciting for them whether they will be able to win the bet they played or not and it is true as you said when luck is on their side, of course it will be very exciting for them because they have won the bet and if they experience defeat, of course they have made a mistake in deciding to continue the bet played.
If you place your last bet, you should be able to control your tension because in that last bet, you will want to win the game but the reality, you will not always win the games. That is why if you decide to leave gambling after the last bet, you should take it easy and not think about the result. Winning and losing can happen in the last bet so you must understand and just leave it like that.
It is really gives happiness if you can win with your last bet but you must realize that will not always happen to you. Usually if people place their last bet, they use more money and hope the last bet can gives them more money too. But again, we must realize that we can lose in our last bet so be careful to manage your tension.
