I can’t help you there , I guess, they’re all working on my end. Have you tried the same games but on other sites? I mean, you can do a search through Google or whatever you use and see if a game like WordWipe is playable on some other site. Arkadium is the site that provides the games here. You can try the games there or better still, contact them directly and tell them of your inability to play.
It's nice to be important but it's more important to be nice.
