Cyber Monday Sale and two new Masterpiece Sudoku Mixes

We’re excited to announce that from now through the end of next Monday, December 6th, any order of $25 or more will get a 20% discount automatically taken off at our web store.

We’re also excited to share the two latest books in our Masterpiece Sudoku Mix series, Arrow Sudoku and Outside Sudoku, each with 25 elegant hand-crafted grids from some of the world’s best Sudoku constructors. If you are not using the above Cyber Monday discount, note that buying any two MSM books and adding the code MASTERPIECE will result in a 10% discount.

Sunday Update and Solutions

Later today we will be releasing two new parts of our Masterpiece Sudoku Mix series, as well as details on a “Cyber Monday” week sale for our puzzle books. As another Thanksgiving Holiday bonus, we finished digitizing four more puzzle styles in our backlog for solving with Penpa-Edit. The new additions are Cave, Castle Wall, Balance Loop, and Statue Park. We are now over 1,150 total puzzles digitized, over half of our website.

Our past week with Tapa-Like Loop puzzles is collected in this PDF and the solutions are in this PDF. More Tapa-Like Loop puzzles can be found in the Tapa-Like Loop Collection by Prasanna Seshadri.

The daily solution videos are on the posts and linked below:

This next week will feature a variety mix with “one grid, two puzzles” where the clues in each grid can be solved in two different ways. We’ll post the first puzzle style at 9 AM PT and the second style at 9 PM PT, but solvers can try to guess what style is the second puzzle in the time between postings. Some will be more obvious than others. And while the 9 AM puzzles will follow our usual Monday-Saturday difficulty progression, the paired puzzles will not. There will also be a Sunday Stumper next week with a seventh puzzle in this set of pairs.
