High Sums/en
Aus Puzzlewiki
Instructions
We are looking at a grid of 9x9 boxes. The objective is to fill the grid with digits so that each column and each row contains all of the digits from 1 to 9. The preprinted number in each box reflects the sum of the orthogonally adjacent larger digits. Casually speaking: the larger digits feed the preprints of the neighbouring smaller digits.
History
High Sums were invented in December 2017 by TPPD / Thade Precht Playful Design. A 9x9 version is presented in the Puzzle Portal.
High Sums are related to Low Sums, while both puzzle types originated from Rooftops.
