As it is now -no URL, no description of the game- it's really hard to give you any advice on what might be the problem with it.
Other than that, try some game communities and forums. Post on some subreddit, publish it on itch.io, etc.
It also looks like you're just straight-up stealing from other sites like y8.com and Gamepix, not even attributing them...
If I were a search engine, I'd probably penalize your site and delist it on purpose because... really... it's just SEO spam that's taking other people's content and adding noise =( You're not adding any new value for your users, you're taking away value because you're just making it harder for them to find the official sites of the games. Did you ask for any of the game authors' permission? It feels kinda shady, TBH...
Basically, you put a bunch of trash games on a page. The effort you made is minimal. And so the result is not something that you can monetize. You cannot reasonably aim to make money for nothing.
The games themselves, as I said, are trash. They are the sort of games spammers use to put out hoping some poor soul will accidentally bite the bait and then distribute malware or whatever. Poor quality games, full of ads, and many of them don't even work. This is the shittier part of the internet.
Given those two points -poor content and very low effort on your part- I can't give you any advice other than tell you that this doesn't even look like a serious effort.
