Well we are all aware that we can't win all the time but the problem as you say is that lately we are not having those victories we used to have,I was playing yesterday my usual 100 usd session in Play n Go slot Swords and Holy Grail and although it kept me playing for so long,gave the bonus round but I did not witness a great x multiplier to my bet not in the normal game nor in the bonus,in fact the bonus looked like it was making fun of me because a lot of times gave just 0.30-0.45 dollars as profit from the bonus round.The game hit a couple of time during normal game play that x100 but not giving a winning combination.I ended up losing like 10 dollars in total so no problem.
Lucky enough you decided to quit when you lost $10, at least although we don't know if it will end well or bad, the money is already secured, considering that some early results showed negative results.
I'm now focusing in the contest of playbetr where I do not need to spend a lot of money but there is a great chance to make good profit from the rewards.
Once I received the reward, I'll back to play and test my luck whether I'll get better luck or my bad luck continues....
If my bad luck continues, I think I'll take a longer break.
I've seen Playbetr contests results for last few weeks, and you're always the winner, look like there is no one can't beat your total spins so far. I myself have never played on playbetr, since I'm only playing at BK8. Once I received the reward, I'll back to play and test my luck whether I'll get better luck or my bad luck continues....
If my bad luck continues, I think I'll take a longer break.
I guess roycilik also had bad days recently with his favorite slots. 
. From this, I conclude that using normal spins is likely to be a waste of time. Although this is back to luck, because from 100 normal spins you can get some bonus features, however, when compared to normal spins and buying bonus free spins, I prefer to use buy free spins.
