I decided to step outside my comfort zone and work with a 9x9 grid for a change ;-) I was teaching integer operations to my students recently and naturally thought about how to make a puzzle out of it. The information is minimal, but I can assure you no bifurcation is necessary. There are, in my opinion, some neat tricks that, if you discover them, will allow for a very smooth solve. Feel free to post a hidden comment below or message me on Discord if you'd like any help! Please be sure to check out my other puzzles here.

Rules:

Each cell contains one of the integers –8 through 8. Numbers cannot repeat in a row, column, 3x3 box, nor in the same position within the boxes (i.e. disjoint rule). Numbers in a cage must sum to the given total. For each box, the numbers form a set of consecutive integers, and the row, column, and diagonals have the same sum (i.e. magic square).

Note: Because you cannot input a negative sign, my suggestion is to shade a cell green for positive and red for negative. So the grid can, for example, contain two 1’s in the same row, but one will need to be green (for 1) and one will need to be red (for –1).
