The concept of a one-trick pony is lost on me.
Normal Sudoku rules apply.
Hot and Cold Cages: Cages are either hot or cold. Hot cages contain positive values and cold cages contain negative values. Digits may repeat in a cage. It's up to the solver to determine if a cage is hot or cold.
Thermo: Values strictly increase from the bulb end of a thermometer.
XV: Cells separated by an X must sum to +10 or -10. Cells separated by a V must sum to +5 or -5. Not all Xs or Vs are necessarily given.
Following your tasty tepid tapas, perhaps you're looking for something with a bit more kick. Try out one of these other hot and cold puzzles (for I can create naught but these).
