All the puzzles from last week have been grouped in this PDF. While Gemini continues, this marks the official end of our twin “Twin Weeks”. I hope you enjoyed the ~24 puzzles over the last couple weeks. I say ~24 as even I’m not sure I’ve found them all.

Next week will debut a slightly new format idea which is the split author week. I’ve let both Prasanna and Serkan focus on a single puzzle type and develop it over three puzzles. Prasanna will take the first three days with Tapa-Like Loop and Serkan will take the last three days with Light and Shadow, a new variant for this site.

The bonus puzzle for our high-level supporters is a Skyscrapers by Grant Fikes.

All the puzzles from last week have been grouped in this PDF. There were a lot of puzzles last week, so even if you think you’ve solved them all it might be worth taking another look.

This week marks Grant Fikes’ birthday, and we will have an unusual mix for the week with puzzles from Grant, Prasanna Seshadri, and guest contributor Bobby Liu. The theme will be quite obvious from the start this week at least. The bonus puzzle for our high-level supporters is a Fillomino by Grant Fikes.

This coming week is another variety week (highlight to view):

Monday: Nurikabe by Prasanna Seshadri
Tuesday: Masyu by Grant Fikes
Wednesday: Tapa-Like Loop by Prasanna Seshadri
Thursday: LITS by Craig Kasper
Friday: Fillomino by Thomas Snyder
Saturday: Statue Park by Prasanna Seshadri

The bonus puzzle for our high-level supporters will be a Fillomino (Cipher) by Grant Fikes.

We’ll have a little more discussion in the comments here later after the dust settles about the puzzles, but we hope everyone enjoyed today’s US Puzzle Championship.

Our puzzlemasters contributed several puzzles to the competition including:

Crosslink by Grant Fikes
Double Minesweeper by Serkan Yürekli
Nurikabe Path by Thomas Snyder
Star Search by Thomas Snyder
Tapa by Serkan Yürekli
Tapa View by Prasanna Seshadri
Wind Shield by Serkan Yürekli
Wordmark by Serkan Yürekli

All the puzzles from last week’s Araf collection have been grouped in this PDF. It seemed to have been well received as a genre so we may choose to feature it more regularly in our rotation. I personally enjoy it a bit more than other intuitive styles like Numberlink, but that could just be a result of it feeling “new” having only solved about twenty Araf puzzles.

This coming week has a mini-theme to it, perhaps “something old, something new”, as half the puzzles will be from guest contributors who have made some interesting puzzles. The rest are from Grant Fikes, who is not so much “old” as familiar. He’s been contributing about a puzzle a day since the start of the year; there will be a collection of the Foxger’s puzzles coming later this year as a book/e-book from GMPuzzles which will be a great book for solvers just learning how to solve some of these types.

The exact schedule for the week is this (highlight to view):

Monday: Star Battle by Grant Fikes
Tuesday: Skyscrapers by Grant Fikes
Wednesday: Fillomino by Walker Anderson
Thursday: Yajilin by Grant Fikes
Friday: Place by Product by Ravi Kumar Macherla
Saturday: Tapa by Murat Can Tonta

The bonus puzzle for our high-level supporters will be a Masyu by Prasanna Seshadri.

All the puzzles from last week’s variety week have been grouped in this PDF. Over the last couple of weeks we’ve also been highlighting some championship puzzles written by puzzlemaster Serkan Yürekli. If you’d like to see his entire 24HPC puzzle set, go here. The Japan dakejanai Zukei dakejanai Puzzle Championship puzzles we featured have not been released yet, but may eventually be here.

Serkan has been an instrumental designer in sharing good ideas from Japan with a wider, western audience; his OAPC series, WPC puzzles, and even his contributions here at Grandmaster Puzzles (like last week’s Dominion originally by Naoki Inaba) are often styles adapted from puzzles he finds in Japanese championships. Next week will focus on another such type, originally a Japanese style 相ダ部屋 that was renamed Araf, meaning “purgatory” in Turkish, by Serkan when I first ran into it at the 2010 World Puzzle Championship. We will have some classic puzzles, and some interesting minor variations.

The bonus puzzle for our high-level supporters will be a Cross the Streams by Grant Fikes. Our Master and above patrons also received a puzzle we believe to be the largest Tapa ever made (it is certainly the largest Tapa Serkan Yürekli has ever written). If you haven’t considered supporting our website yet, now would be a good time to do so.

All the puzzles from last week’s Skyscrapers collection have been grouped in this PDF. Many thanks again to Roland Voigt for the fantastic Skyscrapers; he even made some walkthroughs for the classic puzzles. You’ll find more of Roland’s puzzles here and other content linked from his blog.

Next week will be another variety week with a range of puzzles including a few new variations (highlight to view):

Monday: Battleships by Thomas Snyder
Tuesday: Slitherlink (Sheep and Wolves) by Grant Fikes
Wednesday: TomTom by Grant Fikes
Thursday: Dominion by Serkan Yürekli
Friday: Thermo-Skyscraper Sudoku by Hans van Stippent
Saturday: Heavy Dots by Prasanna Seshadri

The bonus puzzle for our high-level supporters will be a Fillomino by Prasanna Seshadri.

We will also have a few bonus puzzles throughout the week from the recent competition puzzles from Serkan Yürekli. This week they will all be Double Minesweeper puzzles which is a style we plan to feature in a future title from Grandmaster Puzzles.

All the puzzles from last week have been grouped in this PDF.

Next week (including the bonus puzzle for our supporters) will feature just one puzzle style, made by the person we consider the world’s best author of that style: Skyscrapers by Roland Voigt

We will also have a few bonus puzzles throughout the week (and in the coming weeks), which are our favorite recent competition puzzles from Serkan Yürekli. These aren’t really organized by difficulty level, but are also definitely worth checking out.

All the puzzles from last week’s Fillomino focus have been grouped in this PDF.

Next week will be another variety week with these puzzles (highlight to view):
Monday: Sudoku by Thomas Snyder
Tuesday: Negative Tetromino by Serkan Yürekli
Wednesday: Masyu by Thomas Snyder
Thursday: Tapa by Serkan Yürekli
Friday: Star Battle by Thomas Snyder
Saturday: Ripple Effect by Grant Fikes

The bonus puzzle for our high-level supporters will be a 13×13 Nurikabe by Prasanna Seshadri.

All the puzzles from last week have been grouped in this PDF. While we don’t like breaking the rules too often, we hope you enjoyed last week’s “Oddities”. Even the bonus puzzle, the “Nothing Odd Going On Here” Slitherlink, was quite twisted in its execution.

Next week will focus on one of our favorite puzzle types: Fillomino and variations. Puzzles will be by Grant Fikes, Prasanna Seshadri, and Serkan Yürekli. The bonus puzzle will also be from that category, and if our high-level supporters haven’t had their Fillia of puzzles yet, there will be an extra large and rather incredible puzzle sent out by Grant Fikes as well.
