This is the sixth puzzle in a series of seven anchor sudoku puzzles.

This is by far the hardest of the seven puzzles. Its probably similar in difficulty to Poison Arrow which a few people rated as a 6 for difficulty.

Originally I planned for this to be the final puzzle, but thought it would be a little depressing if the final puzzle did not get any solves, so I am moving it become second to last.

Like the previous puzzle, I am included some minor hints to push you in the right direction.

Anchors are like arrows, except you subtract the smallest digit from the sum of the other digits. So for example an anchor with a 5 in the square, and 4,2,3 in the chain would be valid because 5=4+3-2. Repeat digits are allowed so 5,5,1,1 would also be valid because 5=5+1-1.

• House Boat
• Sunken Forest
• Mountain Temple

Standard sudoku rules apply.

Subtracting the smallest number along an anchor from the sum of the other numbers equals the number in the square cell.

The numbers in the cage must sum to the given total in the top left.

Hint 1 for break-in: The break-in uses set theory

Hint 2 for break-in: Try to put a bound on the maximum value for the digits which will be subtracted from the four anchors that go into box 5
