All the puzzles from Tom and Prasanna’s variety week can be found in this PDF.

This next week will be somewhat different and also somewhat challenging. But first, an announcement:

With great pleasure I welcome John Bulten to Grandmaster Puzzles as a new Contributing Puzzlemaster. I haven’t added a new Contributing Puzzlemaster in over a year, and John may be a new name for some of you, but after I ran into amazing puzzle after amazing puzzle in his submissions for our upcoming title The Art of Puzzles 2 I know he would be a great addition to our team.

John is an accomplished cruciverbalist as well as a logic puzzle designer. He’s been published in many places including “Will Shortz’s Wordplay” and “GAMES” (now “GAMES World of Puzzles”). He will regale us with puzzles that often require unique verbal logic as part of our 2015 goal to publish more letter- and word-based puzzles and themes. This week features puzzle overlaps where different styles work together:

Monday: BACA (Easy as ABC/Paint by Numbers)
Tuesday: Litro (LITS/Nanro)
Wednesday: Slithersweeper (Double Minesweeper/Slitherlink)
Thursday: Symmetry Fillomino (Fillomino/Spiral Galaxies)
Friday: Pentapa (Tapa/Pentomino Placement)
Saturday: Hidden Shape Sudoku (Shape Sudoku/Battleship Sudoku)

The bonus puzzle for our high-level supporters will be a Cavestream (Cave/Cross the Streams) by John Bulten.

We’ve been engaging in some new sudoku projects over the last half year; specifically, Grandmaster Puzzles has been supplying hand-crafted sudoku variations to a new magazine called “Will Shortz’s Sudoku”. While the first issue just hit bookstores and newstands, we’ve now completed submissions for three issues. Our Tight Fit Sudoku, Thermo-Sudoku, Arrow Sudoku, Even/Odd Sudoku, Consecutive Sudoku, and Isodoku (nine puzzles from each genre per issue) sit alongside more typical sudoku offerings from Penny Publications.

This next week I wanted to bring together some of the “extra” submissions I’ve gotten in from our authors for that magazine, with two sudoku in each of these styles: Tight Fit, Thermo-Sudoku, and Arrow Sudoku
