Slither.io

This is why I didn't get any blogging done this weekend.

Slither.io is a multi-player game in which you are a vermiform creature.  You control its non-stop motion with your mouse cursor, towards which it always moves (the head stays in the center of the field-of-view). 

You get bigger by eating the colored dots.   You can briefly speed up your motion by left-clicking, but that uses energy and diminishes your size.  You die instantly if you bump into another "worm," as happened to me in the screencap below when the blue-and-yellow "lucky punch" darted in front of my face before I could move.  The resultant bright dots resulting from a death are particularly nutritious, so any death creates a feeding frenzy of nearby "worms."   One way to kill another worm (when you are big enough) is to encircle them and then coil smaller until they are forced to bump into you.  As soon as you die, you can click to be reborn until you've wasted an entire day.  There is no pause option.

That's basically all there is to it.  At the bottom right is a "map" showing your location in a circular world (if you fall of the end you die).  At the bottom left is your status (length and comparison to other participants at that moment).  At the top right is the leaderboard.

This was my best score last night:

That was good enough for the #2 rank at the moment.  I achieved that mostly by letting others fight and die and then scooting in to eat the dots; I spend a lot of time in a defensive coil with my head inside the coil, where nobody could make me bump into them.  I was killed by a tiny little guy who darted in front of me.

All of the above are screencaps.  The game can be played here (and presumably at many other locations).  Some strategy tips are here and here.  Readers are invited to leave their own suggestions, relevant links, and a report of their best score in the Comments below.
