Chrome Sync Supersports is a game roughly resembling Track and Field for the NES which runs in a modern browser that supports web sockets and allows you to use your mobile phone or tablet to control the action.
You log on with your computer and then log on again with your mobile device.
Even though I can understand a bit of Japanese, I can’t really be bothered to read the graphical text on this site. From what I can glean from the visuals, it’s a site with a few minigames which award you with different prizes. One prize is a set of desktop wallpapers of the scantily clad Marine Matsuri girls for example.
All in all the visuals are pretty well done and it’s pretty fun to play with. You should check it out!
A warning, their web server seems to be really slow to download from my location.
