Useless cages
(Published on 9. August 2022, 21:10 by Fool on Hill)
This is a puzzle in which all the cages (which form a spiral) sum to five times the number of cells they contain - hence "useless cages". In fact this is a rather severe constraint and solvers should find that more is given than is apparent on the surface. It may be a little tougher than a 2*.
Puzzle rules
Normal Sudoku rules apply.
In cages digits may not repeat and sum to the total in the top left corner of the cage.
On thermometers, digits increase from the bulb end.
