Normal killer sudoku rules apply, except that instead of using the digits 1 to 9, we'll use the numbers from 2 to 10:

Place a number from 2 to 10 in each cell of the grid so that every row, column, and 3x3 box contains each number exactly once.

The numbers in a cage, defined by the dotted lines, sum to the number in the top left corner.

In addition, a 'no divisors' rule applies: If two numbers are horizontally or vertically adjacent, then neither of them can be a divisor of the other. For example, a 5 can't be next to a 10.

You can solve this in SudokuPad. It won't let you write a 10 in a cell, but the solution check will work if you use 0 to represent 10.
