All of them are great tips, but I think no 6 could be modifed to make it more clear because someone could interprete as gamblers should have enough money so that they can gamble more, you could use "use spare or money you can afford to lose" that sounds better and it's also moe self-explanatory.
Good catch there, I already put a reminder that the budget should be the money they can afford to lose to not create any misunderstanding that the tips are encouraging them to put more money into their gambling session. Although the article clearly stated that:
Why should I record the data of a bet? It is not necessary for me.
I do not try demo, I go for the ones that I know how to play. I mean the ones that I know and they are not hard to play. There are plenty games on casinos.
Why should I make sure I have enough money for gambling when I am only using very tiny amount to gamble. Bank roll management is enough which is not hard. Just take 5% or less of your weekly income to gamble weekly. Also putting a limit to loss.
I do not have to focus on my bet. If I lose I lose. If I win I win. I can afford the lose once it is not beyond my 5% of my weekly income. It is not even getting to 5% that I use to use weekly, usually I use around 2 to 3% weekly to gamble.
The quoted part of the article in my above reply tells the reason. But for us that see gambling as entertainment wouldn't bother that much. I think this kind of tip is for more serious players that see gambling as a way to generate money and keep them at the safe zone at least.
What I see useful are:
Do bankroll management
Learn to accept losses
Know when to quit
I agree with you about these tips are useful to minimize losses. the article is about having an "edge" and at the same time limiting losses while engaging in gambling activity. Just like what @swogerino stated, the advantage of trying the demo and keeping the data and studying it when is to know when the bonus scatter is triggered which is one of the important factors that may influence the fund we can allocate. Information is a very powerful tool so I do not belittle the power of gathering data and statistics.
Gambling results may be random but in some way, it has a range or pattern on when the bonus round will likely trigger.
Shouldn't gambling be fun for the players, and on the other hand, profit for the owners? The majority who approach gambling (and by that I mean casino games) in such a way that they want to beat the house will not succeed regardless of the strategy.
It should be, but there will always be a player that wanted to earn money from gambling activities, worst, there are players that wanted to try to beat the house which often resulted in the players' destruction.
