There are also games that have no effective strategy to play, such as gambling that has no strategy, gambling is based on your money, there are gamblers who are addicted to gambling and are driving themselves to destruction, but they continue to gamble,
I think these gamblers will eventually end on their own, gambling is a mental addiction, these addictions will not become addictions for you.
For gambling that are luck based, there is no strategy at all but it will be based on how you are going to decide. But if they are games like poker and sport betting, there is a strategy with that.
Gambling addiction is being obtained by someone when he reaches to the peak of his own gambling activity. When he cant live a day without gambling and he can do crazy decisions like selling stuff for gambling.
And when it hits you mentally, you have to take caution and solve it either on your own or with the help of people that surrounds you.
