Partially compatible with Firefox 31.0 Rated 3 out of 5 stars

The 1-player mode still works, but to play it you need to install https://addons.mozilla.org/firefox/addon/checkcompatibility/ first, restart Firefox, and look for the game in the "tools" menu.

2-player doesn't work, but everything else checks out okay.

It's funny and entertaining! If you're in the total boredom, just get PONG!

However it seems I cannot play online.

YOU SHOULD GET THIS ADD-ON. Sure Multiplayer isn't always working but the game is still addictive. One should try playing 2 player games its fun.

Great job!! Love this classic and you did a really nice job with the sound fx. Totally cool to be able to play by yourself or with a specific friend online. Pong is a relaxing way to spend a few minutes between tasks. Thanks!!
