I stumbled on this very cool beer bottle cap game. It’s essentially one of those simple memory matching games but uses crowns and flash technology to create a fun little game.

You start out with 36 upside down crowns, after showing you them right-side up for a few seconds.

Then you have to find all the pairs as it times how long it takes. You also get 100 points for each match found but lose 5 points for each wrong guess. You can also make it a little harder by clicking on one of the eight single color crowns to the right of the multicolored one to play a game using crowns of just one color, which is slightly more difficult to play.

Fun stuff. Finally a time suck that I can pretend is really work. Give it a whirl.
