so the best ability to play The slots is the availability of time and money, the tricks come later.

Yes, time is important since slots is a long game. With a decent bankroll, I can spend 7-8 hours in one session. Time flows differently in a slots game so you should schedule your session wisely.
But it is still unbelievable for me to get not even 1 single scatter in 150 spins. Never experienced such bad thing in my slot gambling journey for years. It is usual to get no free spins within 150spins, but not even single scatter? Still waiting the answer from ShowOff on which slot he experienced, even an extreme volatility slot is rare to get no single scatter within 150 spins.
Theoretically, I believe it can happen, but in reality, we rarely observe this thing. Perhaps ShowOff only exaggerates his bad luck. I think I had this no scatter session, but perhaps it was less than 100 spins. I didn't count, really. It's on games that only has scatters on line 2, 3, 4 or only on line 1 and 5.
Well in general terms, slots has a lot to do with being dependent on luck almost entirely, the strategies and everything based for the slots is difficult to apply, the tricks and everything that has to do with the game It already depends on how much the player is willing to lose, because the problem with slot machines is that many times because of the emotion, the music and the casino effect make the brain think that all the time they will win and that can become a weapon double edged.
Well to tell the truth, one of the best slot machines that I have played are in bitcasino, betfury and stake.com, there I have had good experiences, although of course I have also lost, but I have a lot of experience left.
Unfortunately, the only experience that can help is to control bankroll aka getting out while you can or managing bankroll during win/loss streaks. Can't see any other benefit, btw all mentioned websites have the same slot provider source,IIRC.
