# Spider has made it on CTC!

Spider has finally appeared on Cracking The Cryptic! Unfortunately it’s not the right type of spider we know and love. We all know how many words a picture is worth so I’ll just do a screen dump and let you judge for yourself.

I believe every man dog and millipede on the planet must have heard of CTC by now. If you’re not familiar with CTC there’s always Google Search. If you’re not familiar with Google Search you can apply recursion and do a google search on Google Search. Bad jokes aside, this is easily one of the best Sudoku puzzles I have ever come across –

Yes, it’s a Sudoku. With no given digits. Not one. Just a bunch of lines that look like a spider. Plus a black dot between row 9 column 4 and row 9 column 5.

Lucy Audrin has set a number of puzzles for CTC and she also has many interests outside of Sudoku. She is definitely one of the Awesome People, and the world could do with a few more of those!

Oh yes, I should probably mention the rules: Normal Sudoku rules apply. Digits on a “thermometer” must strictly increase starting from the bulb (for example 13678). Some thermos share a common bulb. The black dot indicates two numbers in a ratio of 1:2 but you don’t know which cell is twice the other. It turns out this is enough to enforce a unique solution.

HINT: for those unfamiliar with Thermometer Sudoku, one of the thermometers is length 9, allowing you to enter nine digits immediately.

If you know your Kropki Sudoku, this puzzle has no “negative constraint” i.e. some cells can have consecutive digits or digits in 1:2 ratio despite the absence of a black or white dot.

Let me know if you enjoyed this Sudoku 😊
