### Kjarposko

The Benjamin's Blog's mathematicians at Benjamin's Blog headquarters had spent so much time doing Sudoku, Kakuros, and analysing election results in Harrow-on-the-Hill that one day they decided to get their revenge. They locked to the door, grabbed some shapes, lines, and numbers, and performed some ghastly experiments on them, until, suddenly, one day, they had at last created something with which they could frustrate the world, and, just to make things worse, they gave it the most ridiculous name in the world: the Kjarposko.

It involves a selection of boxes which are linked together. Each box is divided into two sections - there is a number on top and a space underneath.

There's only two rules: every number on top of a box equals the total of the answers in the bottom of the box linked to it and no number may be used more than once. (A list of numbers you may use will be provided).

Confused? Don't panic. Let me guide you through an example.

You need to put 1, 2, and 3 into the three boxes. The box with 4 in it is linked to the boxes with the 3 on top and the 5 on top. Therefore, the numbers you put into the '3' and '5' box must add up to 4. In the same way '3' + '4' = 5 and '4' + '5' = 3.

Righty-ho, then:

I suggest fitting a smoke detector to your head to attempt these.

WARNING

You are now approaching one of the most lethal puzzles on the planet. It is so hard that it is on the edge of meltdown and some of the numbers have evaporated into * symbols. It is still possible to fill in the answers, but if you are of a nervous disposition DO NOT ATTEMPT THIS PUZZLE.

1. Great puzzle! Enjoyed doing all but one of them. Sizzling appears to have an error; I can't see how numbers can be assigned to the four blocks which are connected to the two 22 blocks. Each pair would need 10 and 12, and we can't use any numbers twice. That aside, this is an excellent puzzle, and I'd love to see more.
Well done!
