Is there an alternative way to get the latest casino game patches if the official site is slow?

If the “official” site is being coy, then visit one of the trusted forums such as CasinoGameForums.net or VGCasinoTalk, who often have developers’ own patch links. Or GamePatchMirror, a popular mirror site. If you’re really ambitious, create a wiki page dedicated to tracking patches, and link all of the above, being careful only to link reputable mirrors. You can also encourage users to post working/wrong ones on your forums. Remind everyone to verify hashes or scan with a virus checker, too.

But as a casino game expert, I suggest using only official mirrors or one of the dev's supported P2P programs (uTorrent, etc.), or verifying hashes. Dev teams may also post update trackers on Reddit or Discord servers; search for "game name + patch tracker". Don't download from random websites, they are all scams. You could also consider pinning a discussion thread with verified mirrors to help your community. Hit me up if you'd like more advice!
