This will help solve some of the issues.
Well, the thing about slot machines and the internet is that there are 1000s of options to pick from, so just do what makes you happy then and ignore the rest.
This is why you should look to use casinos that use provably fair slot machine technology, proof of solvency and a good reputation. But thank you for warning the community nonetheless.
Very nice, are they allowing you to cash out? I feel like many times in these spots they withhold or change terms unless you are an established regular.
