Apply classic Sudoku rules : Each row, column and bold-outlined region must contain the digits 1-9 once.

In addition :

• Digits along each thermometer must be strictly increasing from the bulb(s) (round parts) to the end(s).
• Clues outside the grid indicate the sum of the digits between the 1 and the 9 in that row/column.

Furthermore, every sandwich clue is crypted, thus every letter from A-J represents a digit from 0-9. Different letters represent different numbers. Letters in cells correspond to the digit in the cell.

Each symbol ($,£,% etc.) represent a number (can be zero, can be the same as a letter, can be a multiple digit number). The same symbol represent the same number. A ? indicates any digit from 0-9, and can appear multiple times while not hiding the same value. (Yes, it is for esthetic purposes on the grid)

Note :

• No meaningless 0s can appear in the clues (e.g. a "5" clue cannot be written as "05").
• The number AB represent the number for which A is the tens digit, and B the units. It does not means A*B.
