I see nothing in these, personally

Help Gamble sounds like you're helping someone gamble, like you're giving some money to a person to go gamble or if you're blind sitting at a blackjack table

What are my cards, do I hit or stand? Blind person says (lol)

HelpGamble is a good one;

Lots of folks addicted to gambling

Or you could mean, make gambling, easier.

Samer

HelpGamble could be a good website for casino affiliation (like 100$ for registration this kind of thing)

InvestSpin.com - ''invest'' is a cool word, but this combination is simply no good.
HelpGamble.com - just like my buddy @jhm I don't like it either. Like ''help'' whom - casino, by gambling more? Or the other way around - help to fight addiction? Not clear and not convincing, sorry.
PrecisoServizio.com - this combination will not work in English, let alone Italian, with many times smaller markets.
Good luck in any case!

I don't see value in any of these.
