Proof by Exclusion
(Published on 31. March 2026, 22:31 by Neonesque)
To my knowledge, this is a new type of constraint on cages which I have chosen to call Tesbus Cages ("subset" backwards), in analogy with Nabner Lines and Rellik Cages, as no cage is a subset of any other. I hope you are as delighted as I was when I discovered how little was needed to create interesting logic.
Normal 6x6 Sudoku rules apply: Fill the grid with the digits 1-6 so that each digit appears once in every row, column, and 3x2 box.
Thermometers: Digits increase along thermometers starting from the bulb end.
Tesbus Cages: No cage includes every digit from any other cage. Digits in a cage do not repeat.
