I absolutely love games. I love games so much that, unfortunately, I often get side tracked and spend entirely too much time on this site. This website has a bunch of games that you can play from a variety of genres. Granted they aren't games like Modern Warfare or anything that you'd find on Steam or on a console. But there are tower defense games, action, multiplayer games, puzzle and strategy. I haven't even cracked the surface of the games that can be played. I generally stick to tower defense games.
The site also has a chat function on the side of the game screen. The one game that I love playing is Bloons 5. This game is very addictive and I spend far too many hours playing it. I haven't tried the chat function but a lot of the users that do use it seem friendly and offer tips on how to get further in the games. The game has several challenges that you can participate in.
It's a great site and I fully recommend it!
