Each thermo displayed in the right grid must be placed in a unique region on the left grid. Moreover, the position of each thermo must not change with respect to its region (meaning no rotation or translation within the region).

Also note that the answer check will only work when the right side is cleared of digits (though you, of course, may consider yourself finished at the time you place the last digit in the left side of the grid).

An example puzzle is shown below.

Example

Hint 1

Exactly three 1’s are in the bottom row of their box. (The same holds true for any other digit, any other row, or any other column.)

Hint 2

You need to consider at most how many 1’s and how many 2’s can be in the bottom row in conjunction, according to the thermos. Then you need to ask how many there are, according to sudoku rules. (Use Hint 1 for the latter part!)
