Anyone can say and give a site that is trusted even me, so it is better if you will sight your explanation about the sites you are endorsing so that people will do believe in you with a basis.
Your best way to do that is to try it yourself. People in this forum do promote sites on their signatures but you can only be satisfied without any doubt, unless you are delusional, after you play on the site yourself.
To be safe you could try out the most trusted bitcoin gambling websites and I am sure you would be hooked to them and wont ever look back to this. But do be aware that gambling is a luck based game and your losses are your own responsibility. The games are provably fair and they need you to check them using a third party if you doubt their integrity, so learn about provably fair in the meantime.
