AtoZgames.com has been around for a while. Back in the day it ran strictly flash based games, and while we still have them, we have branched into html5 games as well.
AtoZGames.com is free to use, but you may notes some ads. We try to offset the server costs and such with said ads. After all, even free isn't really free, right?
Let us know if there are games you want to see in the future, as well!
