Kakuro Magic BlocksThe secret to solving Kakuro puzzles is learning how to use magic blocks – those special situations where only a single combination of numbers can fit into a block of a given length. For example, if 6 is the sumclue of a block of three squares then the block must consist of the numbers 1+2+3 but not necessarily in this order. When spotting a magic block, the Magic Blocks table can be helpful to identify which unique numbers must be used in that block. The only thing left is to find out in which order the numbers should be organized. This Kakuro Magic Blocks table shows all the magic block possibilities which may occur in Kakuro puzzles.
