Logic Masters Deutschland e.V.

I'm a little late uploading this to LMD, but after his lovely birthday gift to me, it seemed only right to return the favour and set a puzzle for a setter, solver and all round clever chap who has left quite the mark in his first year or so in the community. Happy birthday ChinStrap!



Squishtroquadri: The grid contains four 3x3 boxes, which overlap at the dashed lines. Place a digit from 1-9 in every cell such that a digit does not repeat in a row, column or box.

Cipher: Each letter of CHINSTRAP represents a different digit.

Numbered Rooms: A clue outside the grid shows the digit that must be placed in the Nth cell of that row or column from that direction, where N is the first digit seen.

Product Killer: Digits in a cage multiply to the given total (read as a 3-digit number in base 10).

Kropki: Digits separated by a white dot are consecutive.

(The gold rings have been provided for note-taking)
