Unsolved	Solved

Domino Search was posted several years ago to help solve a puzzle type I found in the book Logical Puzzles, Chartwell Books.  (BTW, Amazon currently has used copies of the book starting at $4.00 shipped at this link.)  In this program, the viewer is given an array of numbers representing dots on the 28 standard dominos, but without the domino outlines.  The player's job is to replace them.  The program was only partially successful because it could generate and solve random arrays it generated, it also allowed users to enter data and supported user play, but it didn't know how to solve those puzzles.  The first step toward fixing this is a separate program which accepts and solves user submitted arrays and saves the array and solution in a file for input to Domino Search.  Domino Search Version 5, and Define Domino Arrays Version 2 posted today are implementations of this strategy.  Perhaps one day I'll get around to rolling them back into one program, but not today. 

June 25, 2013:  Back home from a wonderful family vacation;; one week on a Mediterranean cruise, and a week in Switzerland.  Ports visited were new for most of the family and it's been 8 years since the grandchildren were in Switzerland.  Not much new for us, but we sure enjoyed watching all 8 of them renew friendships.  Much laughter, a few adventures, and no serious misadventures made it a memorable 2 weeks!

Of the dozen or so DFF feedback emails awaiting me here at home, only one so far required a bug fix; the rest were comments or questions acknowledged or answered privately.  Version 5.2 of our Logic Problem Solver program, posted today, allows new problems to be defined even after working on other problems.   Previously, the  "New case" option did not reinitialize fields correctly under those conditions.

Time for one more this month: Word Grid - Complete 3 Letter Words,  to solve, or at least help solve, puzzles such as this one.  Insert a 6 letter word into the top row of a 6x3 grid to form 6 three letter words in the vertical columns.  Oh, and for this particular puzzle, the missing word must be a bird species.
