Hello, who can advise me where I can play slots without spending my own money to start with?

I recently found this demo by chance and thought I'd give it a go on https://plinko.app/demo. The gameplay is straightforward but surprisingly engaging, as I got to drop a virtual ball and watch it bounce around until it landed on a reward. Playing from the US, I didn’t have any access issues, and the demo was a fun, no-pressure way to get a feel for it. It was nice to explore something new, and I can see myself coming back to the full version when I have more time to spare.
