Monday Mutant 113: Blackbarrier Jam (multiplicative)

In this Blackbarrier Jam puzzle, a number indicates the product of two quantities: the number of white cells in an uninterrupted horizontal line from that cell (up to the perimeter or black cells, and including the cell itself), and the number of white cells in an uninterrupted vertical line from that cell (up to the perimeter or black cells, and including the cell itself). The rules are otherwise unchanged.

I'm being commissioned to write puzzles for an iPhone/Windows Phone app; here's a preview of the type of puzzling you can expect to see.

Puzzle 558: Blackbarrier Jam 19

It seems I have a terrible habit of letting my blog go unnoticed (particularly as regards Monday Mutants) whenever I'm being commissioned to write a bunch of puzzles. I will try to fix this.

In unrelated news, my blog is ranked #12 on InterestingBlogs.org's rankings, right ahead of some blog that hasn't been updated since 2010 and right behind a blog about cats. Come on, guys. You're doing a disservice to other great puzzlers like Tom Collyer, Palmer Mebane, and Thomas Snyder when the random Texan, and not any of the actual world puzzle champions, is the guy who's almost as good as cats. If you enjoy their blogs, please click the boost button on their respective directory listings, and do not, under any circumstances, click the boost button on mine.

Puzzle 557: Blackbarrier Jam 18

David Millar of The Griddle is currently seeking funding for a Kickstarter project! The goal is to raise $2000 in pledges to publish a book of paranormal-themed logic puzzles, including Area 51 (a hybrid of Masyu, Corral/Bag, and the Sheep and Wolves variation of Slitherlink) and Haunted Mirror Mazes (a puzzle about locating ghosts, zombies, and vampires based on the knowledge of each one's visibility with and without mirrors). There are rewards for backing at various levels, such as a free PDF copy of the final book, or (if you're feeling really generous) a personal visit from Mr. Millar himself! Do not be afraid to join me in backing this project. :)

A shout-out to Virmir, as well, for creating my blog's new banner!

Monday Mutant 58: Blackbarrier Jam / Streaming Content (cipher)

In the Blackbarrier Jam puzzle on the left and in the Streaming Content puzzle on the right, the given numbers have been replaced by letters; all instances of a particular letter represent the same number, but two different letters must represent different numbers. (This applies whether the letters are in the same grid or not.) The rules are otherwise unchanged.

My most sincere apologies for today's Monday Mutant being late; I was debating whether to put the series on hold for the holidays, but decided against it a few hours ago.

Evil Zinger 12: Blackbarrier Jam (domino)

In this Blackbarrier Jam puzzle, instead of no two black cells being allowed to share an edge, every black cell must share an edge with EXACTLY ONE other black cell. The rules are otherwise unchanged.Haven't I done this variant before? Yep. Expect more Evil Zinger (EZ) revisits of my previous ideas.

Monday Mutant 15: Blackbarrier Jam (domino)

Monday Mutants is a series in which I will attempt to experiment with "mutant" puzzles. These could be existing puzzle types with an unusual change in the rules, hybrids combining elements from multiple puzzle types, or puzzle types neither invented nor popularized by Nikoli.

Monday Mutant 7: Blackbarrier Jam (multiples of 3)

Monday Mutants is a series in which I will attempt to experiment with "mutant" puzzles. These could be existing puzzle types with an unusual change in the rules, hybrids combining elements from multiple puzzle types, or puzzle types neither invented nor popularized by Nikoli.
In this Blackbarrier Jam puzzle, only multiples of 3 are shown. Circles without a number represent a number that isn't a multiple of 3. The rules are otherwise unchanged.
