Puzzle 600: Tetra Firma 40
Remember that contest where a guy named Jeff won a book of LITS puzzles? Well, he already had that book, so here is his substitute prize! Thank you, Jeff (or Jangler, as you prefer to be called), for being an awesome reader.
Puzzle 599: Proof of Quilt 10
Remember that contest where you voted and decided that I can't post puzzles with more than 289 cells until puzzle 600? Well, this is puzzle 599! Look forward to some giant fun soon!
Puzzle 597: Straight and Arrow 42
Joshua Zucker took me up on my recent offer to throw in a free re-gifted calendar with 365 handmade Sudoku puzzles with the $25 purchase of my amazing board game Battle of LITS. In deciding what type of puzzle to make for him, I looked at his initials and immediately thought of "Party in the USA" ("And a Jay-Z song was on. . ."). Then I thought of the oft-neglected J and Z tetrominoes, which are really just mirror images of L and S, and therefore given no special treatment in Battle of LITS. These tetrominoes are the stars of this puzzle. Would you like to see what kind of puzzle your name inspires? I still have extra copies of Battle of LITS. . . . :)
Puzzle 595: Crowd Nine 12
Does anybody want a 2013 Sudoku Calendar with 365 handmade puzzles by Nikoli? I got it as a belated gift earlier this month, and I'd rather work on the puzzles in my unsolved volumes of Gekikara Sudoku than catch up. Don't forget that I'm selling my extra copies of Battle of LITS, my two-player board game based on one of my favorite Nikoli puzzles, for $25 apiece; I'll throw the calendar in for free as a sweetener! But remember: my supply of the calendar is even more limited than my supply of the game. . . . :) [Edit 2013-03-07: This offer has been accepted!]
Puzzle 594: Polyominous 54
A beginner-friendly puzzle. You know, just in case people who are new to puzzles still read my blog.
Monday Mutant 130: Cross the Streams (domino)
Shade in dominoes such that the black cells are all connected to each
other through their edges, and no 2x2 cell area within the grid
contains all black cells. Numbers to the left of a row or above a column represent the groups of
consecutive black cells which are in that row or column. For example, a
clue of "3" means the row or column has three consecutive black cells,
and a clue of "3 1" means that the row or column has a group of three
consecutive black cells followed by a single black cell, separated by at
least one white cell. A question mark (?) represents a group of
consecutive black cells whose size is unknown; an asterisk (*)
represents any number of unknown groups of black cells, including none at all.
Inspired by this Nurikabe puzzle.
Monday Mutant 129: Streaming Content / Tetra Firma
Shade in tetrominoes in simultaneous accordance with the rules of Streaming Content and the rules of Tetra Firma. (As the grid isn't partitioned into regions, the rule of Tetra Firma that every region contains one tetromino is waived.)
Is it possible to create a 10x10 puzzle with these rules and only 4's as givens? I don't doubt it, but I lack the patience to do so at this time. Maybe one of my clever readers can accomplish it. :)
Monday Mutant 128: Cross the Streams
Shade in some cells black such that the black cells are all connected to
each other through their edges, and no 2x2 cell area within the grid
contains all black cells. Numbers to the left of a row or above a
column represent the groups of consecutive black cells which are in
that row or column. For example, a clue of "3" means the row or column
has three consecutive black cells, and a clue of "3 1" means that the
row or column has a group of three consecutive black cells followed
by a single black cell, separated by at least one white cell. A
question mark (?) represents a group of consecutive black cells whose
size is unknown; an asterisk (*) represents any number of unknown
groups of black cells, including none at all.
Monday Mutant 127: Cross the Streams / Tetra Firma
Monday Mutant 126: Bridged Series (prime/composite)
In this Bridged Series puzzle, the prime numbers 2, 3, 5, and 7 are represented by P, and the composite numbers 4, 6, and 8 are represented by C. The rules are otherwise unchanged.
Rules -- Bridged Series
Bridged Series was invented by the Japanese puzzle company Nikoli (under the name Hashiwokakero).
1. Draw horizontal and vertical bridges (diagonal bridges are not allowed) between the islands according to the following rules.
2. A number on an island indicates how many bridges are connected to that island.
3. At most two bridges can connect a pair of islands.
4. A bridge may not cross over an island or another bridge.
5. All of the islands must be connected via the bridges. (It must be possible to get from any island to any other island using the bridges.)
