Monday Mutant 88: Quad-Wrangle / Battleships
Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. The cells which do not contain ships must be divided into rectangles according to the rules of Quad-Wrangle.

Monday Mutant 87: Polyominous / Quad-Wrangle
In this Polyominous puzzle, every region must be shaped like a rectangle. (Thus, the puzzle is similar to a Quad-Wrangle puzzle, but without the restriction that every region must contain exactly one number, and with the restriction that regions with the same area may not share an edge.) The rules are otherwise unchanged.
Better late than never.

Logicsmith Exhibition 5: Polyominous
Would you like to try your hand at logicsmithing, and possibly be featured on my blog? Read on!
Your challenge is to compose a uniquely solvable 10x10 Polyominous puzzle. Your puzzle must have precisely 36 givens, arranged in a pattern with 180-degree rotational symmetry, and every integer from 1 through 9 must appear as a given exactly four times. You are only allowed to submit one puzzle, but you may change it at any time before the deadline. Send your puzzle to glmathgrant[at]gmail[dot]com.
This time around, Logicsmith Exhibition is also a contest! Once the deadline has passed, I will publish all of the puzzles I received without revealing the authors, and ask everyone reading this blog to cast their votes for their favorite puzzles (again via email). If your puzzle is the readers' favorite, you could win a prize!
By entering the contest, you agree to the following terms:
a) You agree not to discuss your entry with any other entrants or any voters until the contest is over.
b) You agree not to cheat the voting system.
c) You agree to provide me with a mailing address in the event that you win and wish to receive a prize, and to await said prize patiently, particularly if you live outside the continental United States. (In return, I agree not to use your mailing address for any malicious purposes, such as sending junk mail or other undesired things.) If you don't want to give out your mailing address, I reserve the right to happily give the prize to someone else who will.
After four weeks (meaning the deadline is August 3), I will post the puzzles that my readers and I have constructed, and give the readers another four weeks to cast their votes for the best puzzles. Good luck, and have fun!

As as few of my readers have noticed, I've finally gotten around to adding sharing buttons to this blog, including Google's new +1 button. They are located very unobtrusively just below the title of each post, in the "Posted on July 4, 2011" line. If you're a long-time reader and there are older puzzles you found particularly memorable, feel free to search the archives for them and +1 them!
