Kakuro 10x10 # 6 Hard

Kakuro 10x10 # 6 Hard

The kakuro is a numerical puzzle that has become quite popular since 2006, on the wave of the success of sudoku. In reality he had already arrived in Italy in the early eighties, with the name of Crucisomme on the pages of the magazine Cruciverba e Passatempi.

Fill in the scheme with the numbers from 1 to 9 knowing that:

• the numbers shown as definitions represent the sum of the digits to be entered in the corresponding white boxes;
• the numbers in the lower triangles are the vertical definitions, those in the upper triangles are the horizontal ones;
• within each sum, each figure can appear only once.

To solve the schemes you can help yourself with the obligatory numbers, which can be consulted by downloading the «Unique sum table» on the left.
