Yes, I think responsible gambling tools are genuinely useful, especially deposit and loss limits. I like having a fixed boundary because it stops me from making a quick decision after a bad session. Session reminders can also help when you lose track of time. They may seem simple, but having those limits set before playing makes a big difference.
I think the most useful tip is to remember that no slot has a guaranteed winning pattern. I usually check the RTP and set a small budget before playing. A lucky streak can happen, but I never count on it. For me, knowing when to stop is probably more valuable than any “secret” slot trick.
