Words about the Feb. 15th,a near miss of a huge asteroid hitting Russia again.  It happened on the same day in 1908.  This one missed a populated city in the Ural mountains.  There was some damage from the pressure of the explosion about 20 Kilometers east in the air while it was crashing outside of Chelyabinsk.  Many windows & building were damage.  1,200 locals were injured.  The asteroid was flying at 18 kilometers per second.  Equivalent of up too 500,000 tons of TNT.

Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

There are now buttons on the puzzle so that you can get a clean page, in either HTML or PDF, that you can use your browser's print button to print. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
