With games that are purely based on luck, there is little to no strategy that we can use. However, we can do bankroll management and session management with games that are based on luck. But these are really hard to do that is why we just play for fun and entertainment.
In games where the odds are against us its better to control our bankroll and time of playing more than the urge of playing. But then one needs to focus on other things to keep themselves away from the games otherwise the craving will eventually take over. In the long term the net profit for any player is negative. Hence one must have control over the games or better yet dont gamble at all.
