Help Features

 New day, new puzzle. Still at the 'Tough' level, decided to use the tools on

the interface to help me. Not the 'check', which is unsporting to my mind, but

the 'hints', which save me paperwork, and the 'colors' to help me visualize broader

patterns. Below:

My new puzzle: column 7 needs an 8 and a 9. At the very bottom, therr already

is a 9 on the line, so the 8 goes there...

                                                                       

Sure enough, if I ask for hints, 8 is the only possibility on that square!

Once I have accomplished that, row 7 at the end shows only 1 and 5 as possible,

whereas it showed 1, 5, 8 prevously. The hints feature is a win!

My new gameboard seems a tad daunting. Maybe I should call the colored tiles feature.

Look at that, there is a 4 in rows 7 and , which gives me a sure 4 on row 9 to the

laft of the 2!!

Solved a 'Tough' problem by the force of intellect alone, no guessing. Could not have done 

it without both the hints and the colored numbers. Ended up near the end with the same two numbers 

potentially playing in so many places it was dizzying. Turned out the solution came from working with 

one of the other numbers.

The computer showed me tough love on this one, and flashed 'not solved' the first time I thought

I was finished. It only undoes placed numbers in the reverse order in which they were added to

the grid, which no doubt saved my sanity...

"Brutal' tomorrow! I need to do something else for a while.
