Quad Clue Sudoku

Josh — Sun, 30 Nov 2008 21:05:56 +0000

The Griddle has another sudoku variation up called Quad Clue Sudoku. This variation features a six by six sudoku grid with four numbers at some of the grid intersection points. These four numbers correspond to the four numbers in the four ajoining squares. It’s another way of providing starting clues, without telling you exactly where they are. Enjoy!

Wordplay Blog

The New York Times has started up a new blog called Wordplay and it is, not surprisingly, a crossword puzzle themed blog. I looked through some of the previous posts and most of them seem to be about the NYT crossword that day, with a few news items about Will Shortz sprinkled in.

iRectangles

Josh — Wed, 19 Nov 2008 01:38:15 +0000

iRectangles is yet another puzzle app for the iPhone. This app is based on the nikoli puzzle sikaku. For the puzzle, you are given a grid of arbitrary size. Some of the individual squares in the grid have numbers in them. These numbers correspond to the number of squares in a rectangle. The object of the puzzle is to section off the grid into a collection of rectangles such that each rectangle has a single number in it that is the rectangle’s area. There should be no spaces left over in the grid.

I’ve found a couple sites, just by googling, that has some examples of the puzzle that you can try. And, of course, there is always the iPhone app.

Texas Holdem Puzzles on the web

Back in January, I wrote about an idea for Texas Holdem puzzles. One of the recent coments on that post directed me to a site with puzzles exactly like the ones I described. Check it out.

Tredoku

Tredoku is another sudoku variation. In a tredoku puzzle, the grid is laid out in varrying three dimensional patterns. The same rules still apply. The same numbers can not appear in the same rows or columns or the same internal square. In Tredoku, rows and columns continue even over 90 degree turns in the grid.

The main advantage here is that grid orientations are virtually endless. And it’s a little bit neater than massively overlapping sudoku grids. There’s currently a tredoku blog set up where you can go and try some of the puzzles. Enjoy!

Trigears

Josh — Thu, 13 Nov 2008 22:36:59 +0000

From the MAKE blog: A new puzzle called Trigears. Trigears is a set of three gears that must be positioned so that all three gears mesh at a single point and the gears do not jam when they spin. One of the creators notes that there are no other puzzles like it. I can’t think of one. The puzzles were made in a very limited run so, if you want to buy one at Puzzle Palace, it will cost you $425.

Grid Fill Puzzles

Josh — Mon, 10 Nov 2008 20:13:53 +0000

From The Griddle, a new puzzle called Grid Fill. In Grid Fill, you are given a set of words and a grid. The words fit into the grid taking up either an entire row, or one of the marked off internal areas. The puzzle part comes in because the rows and the marked off areas overlap. It’s really more of a logic puzzle like Sudoku instead of a word puzzle. Enjoy!

Josh — Thu, 23 Oct 2008 22:27:12 +0000

There is a new puzzle up at Smartkit called Untouchable that was written by Peter Grabarchuk. The goal is to arrange a group of hexominoes in a grid so that they don’t touch. Smartkit is giving away prizes for those who can solve the puzzle first.

CrosScan

Josh — Fri, 17 Oct 2008 21:13:57 +0000

There was a post on Passion for Puzzles recently about CrosScan puzzles. CrosScan puzzles are billed as a combination of crossword puzzles and word search puzzle. What this means is that the puzzle is essentially a word search puzzle but instead of a list of words, you are giving a list of clues to decipher. You then need to find the word in the word search grid.

I have a couple thoughts on this puzzle type. First, it may be harder than a crossoword because the answers to clues don’t really help you at all for the others. The clues generally form a theme, but that’s about all you get. You don’t get letter clues. My second thought is that it seems like it’s possible to find the wrong answer. I may get the wrong answer for the clue, but as long as I can find the right letters in the grid, I’ll never know it was a wrong answer. I think there needs to be some kind of final answer, like a word made up of unused letters. That could help solve the problem.

Puzzles of Leonid Mochalov

Josh — Wed, 15 Oct 2008 14:52:36 +0000

I got an email from Leonid Mochalov, a Russian puzzle inventor. He was drawing my attention to his web site which features many original puzzles, some of which are very unique.

The puzzle types on his page include Squarewords, a sudoku like puzzle involving words, and Express-Labyrinth, a maze-like puzzle that requires you to visit every square in a grid. The site also shows us a number of Mochalov’s block puzzles including a “Chess Cube” that you can print out and try to construct for yourself.
