I would like to try playing at one, but I haven't decided which yet. I used to play slots occasionally, but that was a long time ago, so I've forgotten how it all works. Could you recommend a platform with a good sign-up bonus so I can really test out the casino? Do you know of any? Where is the best place for a beginner to start?

So, you do have some gaming experience after all! By the way, be sure to play the slots from Kalamba after you register. They're a really cool provider. As for the platform, I honestly don't know of any others that give bonuses. I registered with American Luck, and their bonus is pretty good: 70,000 GC + 6 SC. However, to receive the American Luck sign up bonus, you must complete a few steps. For example, you have to confirm your email address. You will receive ~12,500 GC + 1.25 SC for doing so. You'll receive a total of 70,000 GC + 6 SC, which is enough to test the games without spending your own coins. I don't know if you'll like it, but I find this casino comfortable, and the initial bonuses are substantial.
