Fillomino-Fillia 2!

Remember Fillomino-Fillia? Palmer Mebane and I are proud to present Fillomino-Fillia 2! I was hoping that Norzman, the guy who designed the shirt I'm giving away for ChipIn for Children's Charities, might have time to create some new artwork for this sequel to keep things feeling fresh, but it was not meant to be. Don't let the old artwork fool you, though; the puzzles will be entirely fresh! The answer entry mechanism will be different, too: now you have to enter merely 8 digits instead of 20. Other fresh things will be present, too.

Just like last year, we'll be posting preview puzzles on our blogs to help you be prepared for the excitement to come. Keep an eye on this blog and on Palmer Mebane's blog this week!

Puzzle 577: Proof of Quilt 9

I'm posting a 10x18 puzzle at 10:18 on 10-18! Aren't I delightful?

Rules of Proof of Quilt

Monday Mutant 118: Cross the Streams / Tetra Firma

Shade in tetrominoes 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. No two congruent tetrominoes may share an edge, even if they are rotated or reflected versions of each other. 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 Mutants return again!

Puzzle 576: Proof of Quilt 8

Norzman has finished designing the front of the T-shirt I'll be giving away for ChipIn for Children's Charities! I will soon order myself a copy of the shirt; if you'd like a chance to win your own shirt, just solve all three of the contest puzzles! You don't even have to donate! What could be a better excuse to solve puzzles than a free shirt?
