Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply.

The digits in the cage sum to the small number in the corner.

The lines are palindromes. Digits on a palindrome read the same forwards and backwards.

Some cells in the grid are super doublers. There is one super doubler in every box, row and column. The digits from 1 to 9 each appear once in a cell that is a super doubler.

The super doublers double the values of digits for the purposes of cages and palindromes. A super doubler will double the value of the digit in its cell and in all cells next to it, including cells that are next to it diagonally.

A digit affected by multiple super doublers gets doubled multiple times.
