February Prime month (2) - Prime killer (A)
Place the digits from 1 tot 9 in every row, column and 3x3-block. The small numbers in the dotted outlined areas are the sums of the digits in that area. Within a dotted outlined area all digits must be different. Some of the cage sums are replaced by a 'P'. Those cage sums are a prime number.
Here are two tips for beginners in a tiny font. (Copy them into a text editor and enlarge the font size if you want to read.)
1. Prime = odd!
2. Sum R5C4+R5C6 = 3; Sum R4C5+R6C5 = 13; R5C5 = 9
