Yes, online slots casinos are trustworthy as long as you know where to go. The vast majority of online casinos are completely safe places where you can play and earn real money. However, there are some scam sites out there too. That's why it's important to understand the signs of a trustworthy casino site.

Most sessions on slot machines will result in losing money, and there's nothing you can do to chance that. Sometimes you'll win at slots, and even win big. Enjoy those times when they come. But never bet money you can't afford to lose, and be sure you're playing games that fit your bankroll.

Free play refers to a specific type of promotion that is offered by some casinos, in which players are given a certain amount of money to use on certain games, usually slot machines. This money is not real money, but rather a form of "play money" that can be used to play the games but cannot be cashed out or withdrawn.

A Free Play is a bonus play that allows you to place a bet without any risk. For example, if you place aR$55 real money wager at -110 odds, this will be riskingR$55 to winR$50. However, with aR$55 Free Play, there is zero risk so this becomesR$0 to winR$50. If you lose, there is no change to your real money balance.
