Tuesdoku Tip: Part II | 12/13/05
Who's ready for their Tuesdoku tip? You are! Well let's see here. Our goal is to see what goe in the yellow square. According to the row it's in it has to be a 5 or a 9, right? Yes. We use the column it's to figure out which one. If we put a 9 in the yellow square a 5 has to go into the red box or the square beneath it to satisfy the column's quest for a 5. No can do. The yellow square has to be a 5. Another way to determine it is knowing we a 5 in each column. If the blue square is a 5 then the red square too must be a five which conflicts with the 5 in the red box's column. Bam.
