Here's yet another way to challenge your brain.  I must admit, I've never done a Sudoku puzzle but I'm about to start.  Let me know what you think about these games.  I'll keep searching the web for more additions.    Steve

Below is a fun mental exercise that will help your memory.  Give it a try. Once you click on the "start here" button, the images will shuffle.  When they stop, it's your goal to find all the pairs by clicking on them.  If you click on a pair, the 2 images will stay on the screen.  If you're wrong, the images will disappear.  Remember where they were as you progress through other tries.  The key is to find all the pairs in the least number of moves.  Have fun!

Ok.  Here's your next challenge.   Play this simple game once per day and see if you can beat your time each time you do it.  It consists of pretty simple math problems.  Good luck.
