Next week, I’ll post the less extreme ending of Manuel Castillo’s Only Extreme 3 that Gordon Fick sent me, and we’ll get on with the Only Extreme review. I don’t expect any more naughty 5-stars like this one, disturbing the Sunday morning peace. Sudoku is a number-placing puzzle based on a 9x9 grid with several given numbers. It seems to require a one-term Sue de Coq, but one that could have been spotted in line marking. Although BJ readers may question that with the 9/24/17 5-star I sat down to yesterday. Ouch! The unintended multiple solutions explain the sudden jump in difficulty from basic to extreme. Blue, red, and tan accompany yellow, and an independent extended rectangle emerges, for four more solutions.įinally, aqua/orange/blue trials add two solutions, and aqua/orange/green provide the newspaper’s, the double sized. The multiple solution justifies going back to yellow in the red trial to pick up the rectangle multiple. In the trial, yellow would generate a two- solution rectangle.ĭiscarding yellow, evidence of multiple solution appears as aqua and tan generate a four line extended rectangle in the East tower, while aqua and pink bring a third solution. No further conflicts, so I start a red trial. The object is to fill all empty squares so that the numbers 1 to 9 appear exactly once in each row, column and 3x3 box, and the sum of the numbers in each area is equal to the clue in the area’s top-left corner. I added pink/tan and aqua/yellow clusters. Each puzzle consists of a 9x9 Sudoku grid containing areas surrounded by gray or dotted lines. green conflict in r7 means blue or orange or both are true. Nothing worked for me until this very indecisive coloring trap and possible bridge prompted more clusters. Huge brain-bashing Mega Sudoku puzzles, also known as Monster Sudoku, are offered for iPad only. The difficult line marking, and just getting through basic, were signs that this was not my typical Sunday treat.įortunately, I got it transcribed to the template before the newsprint version became unreadable. Play six different Sudoku variations in a single app Start with classic Sudoku grids and advance to Diagonal Sudoku, Irregular Sudoku and OddEven Sudoku - each with a different look and a unique twist of brain challenging logic. You get another demonstration of coloring as a humanly practical way to deal with multiple solutions. After no other advanced progress, a four cluster coloring proves 10 solutions. This one breaks tradition by surviving Sysudoku basic, and with a heavy line marking. My Sunday morning ritual Sudoku, the Dave Green 5-star of September 3, 2017, sent me upstairs for PowerPoint support.
