Most casino websites restrict many African countries from accessing their website although I don't know the reason for their decision but maybe is based on some policy or licence issues anyway there are still some few tricks you can use to access casino websites that restricts your country from visiting their website all you need to do is get a vpn (virtual private server) whether free or paid.
I personally recommend you to use windscribe VPN, set the location to United States and try accessing the website if it doesn't work set the location to Canada and it will surely work out note that you will have to set the VPN to the same location whenever you want to access the website.
