Hi friends, I had a few questions.
What is the best VPS Anti attack and Website anti ddos (free) and how can I get it, does it need a visa card or is it completely free?
Please share the sites that offer this package for free. Thank you

Kudos to @Mashiro for probably one of the most excellent posts I've seen trying to communicate information.  

To be honest @hamed.  When I first read the content of your OP I had this vision of a VPS or Website owner closing his eyes and shaking his head.  Do not provide space to this individual.  As chaos is coming.  Why would you require anti attack hosting?  

Better request would be.  You're into running games servers.  As such you would need hosting that provides for ddos protection that is inclusive of the price of hosting or free.  That is a reasonable request that a hosting owner would understand and respect and respond to.

Best places to look for are sponsors who are dedicated providers of hosting for games servers.  Hosting for games servers are on a totally different level than normal VPS use.  It requires a higher level of protection.  So telling the host that you need the hosting for games servers, would immediately give him a framework of reference.  He can tell you straight out (such as Gigarocket used to do), that he's not into supporting games servers, or he will tell you that is a specialty.  Usually it will be included in the price of the VPS BUT you may pay more for the VPS compared with a VPS that doesn't require that high level of protection.  That makes sense doesn't it?  As to make your VPS more robust for protection, is going to cost extra for the host in terms of additional software and hardening the server.  That host will also need to provide more savvy admin support.

We do currently have a sponsor at post4vps who provides ddos protected hosting for games servers - Evolution Host.  You can check they have a whole section on how their protection works.

Evolution Host are also providers of dedicated games hosting - which for me says they are experts in knowing all of the pros and cons.  And if there should be any issues they will help you.  One of our members, @Khadeer143 has just good things to say about Evolution Host. He qualified for a free Evolution Host VPS last year. Evolution Host offers free VPS on the basis of having an already existing Website that scores 20 on SEO Ranking using this tool. I don't know if Evolution Host still provides this service, but I was able to find more info at the link below at Lowendbox:

So you could try them out.  I won't recommend their sponsored VPS 10 to you, as it is not on the same level as their paid VPSs.  But they should be good with what they do and understand what you want because they are specialists with games servers.

Bottomline.  There isn't "free" for this high level of protection.  The real protection has to come from the host on a server that is dedicated for that high level of protection.  That is why you get hosts who refuse to run their servers for games.  As they haven't set up their servers for high-level protection that is needed for games and that would put their servers at risk.  So you need to find the hosts who are dedicated games servers hosts and be willing to pay for this.

Alternative is to just be very careful and not open your server to unnecessary risks or draw unnecessary attention to your server.  Try to keep a low profile that isn't noticed and doesn't open you to attacks.  Cloudflare makes sense to use, but again, doesn't provide the kind of protection you're asking for as it has to come top down from how the server is set up by the host.  You could also check out games server forums as you may be able to find tips there of how to protect your server as much as you can "for free".
