I just came across something very interesting. YouTube has added the Classic Snake Game to its video player!! If you are on a low-bandwidth this would be great to kill some time till the video loads.
Its seems to work in all the video, Here how you get it to work :
1. Pause the video.
2. Continuously press the left arrow key.
3. Notice the rotating loading indicator just go straight.
Thats it, use arrows to control it and find the dots!
I tried it and have to admit that its pretty hard controlling that snake.
Its unclear how long this has been available in youtube. This feature was never announced.
