Anyone know legit ways to get free slots coins from Instagram?

I keep seeing posts and ads about 'quick hit slots' and free coins circulating on Instagram, but I'm really skeptical. Most of the links seem to lead to sketchy sites, and I don't want to risk my personal info or any real money. Has anyone here found a reliable method or a specific account that genuinely gives out free credits without needing to download questionable apps? I'd appreciate any advice on how to verify if these promotions are safe and actually work for a decent spin count. Thanks in advance for the help!
