Our most recent week of LITS puzzles can be found in this PDF.

This year we are working to reconstruct parts of our website to be more friendly for beginning solvers who are not familiar with all of these types. One part of this plan includes a new book, that we are releasing online today, called Intro to GMPuzzles by Serkan Yürekli. Serkan has constructed 252 elegant puzzles across 12 genres (21 puzzles per genre) to introduce solvers to the beauty and logic possible in Sudoku, Tapa, and other puzzle styles featured regularly at Grandmaster Puzzles. The puzzles are on the easy-medium side of difficulty, perfect for beginners but with some tricks and Aha moments even experienced solvers will enjoy.

So to mark the release of the book, we will have a 12-puzzle sampler this week with one puzzle from each genre released throughout the week. We’ll be back next week with a new variety mix week.
