The coloring is cosmetic, but I like to think of this grid as a rocket, heading into space. It’s a lot of cages, combining in interesting ways, and might provide a nice solving exercise for someone on a long voyage through space.
Rules:
Normal Sudoku rules apply.
Digits within cages sum to the small number in the top left corner of the cage.
Estimated difficulty: 1 out of 5
