the thing with sudo³ is ... it's not that hard. it's just involved. so it's easy to go awry.

take baby steps. and for goodness sake - use a pencil!

huzzah!

let's just recap the rules for this one:

the puzzle uses 9 letters instead of numbers. it consists of 5 overlapping sudoku grids (the large 9x9 squares). within each of these 5 grids, every row, column and internal 3x3 square must contain each of the 9 letters exactly once.

solve the crossword clues ... solve the sudoku. I've tried to make the clues moderate-doable, and the resulting sudoku moderate-tough.

after more than 7 months, I'm still working my way through posting my back-collection of ultrasudoku and sudoku3 puzzles. but I do still like to create these from time to time - here's a good 'n tough one I made just the other day.

I am still so in love with this cute little word 'n' sudoko variant. I'm sure it's possible to make these at the solvability level where they could happily appear in your average daily American newspaper (next to - or instead of - the stupid Jumble.)

I think, difficulty-vs-fun-wise, I'm about there with this puzzle.

I'm not really happy with the way this one turned out (since as I was checking the clues I found out 8 across is actually an alternate spelling. bother.)

but I'm posting it anyway. what the hey.

I finally got this form worked out. the secret is not to worry about symmetry, and just go for it.

this is a good one! (if I do say so myself). I'll definitely be making some more of these, as above, with no 'given' letters.

here's a 6x6 version of algebraic sudoku ... much easier to solve than the full-size ones because of the smaller grid, and because it only uses the numbers 1 through 6.

in this puzzle, each row is designated by a letter A through I, and each column by J through R. this gives each cell a distinct 2-letter identifier - e.g. AJ is the cell in the top-left.

the clues give algebraic relations between the numbers in various cells. for instance, in cell AN the formula BQ+CP means that the number in AN is the sum of the numbers in cells BQ and CP.

in the completed puzzle, each row, column and 3x3 square will contain the numbers 1 through 9.

in case it's not clear, the formula in CL is CP to the power of BK.

this puzzle uses 9 letters instead of numbers. the diagonals (reading left to right) spell words related to the puzzle's theme.

you'll have to figure out the words in order to solve the puzzle!

in the completed puzzle, each row, column and 3x3 square will contain all 9 letters. (the diagonals do not necessarily contain all 9 letters - each word can use the same letter more than once.)

astute readers will note this puzzle has only eight letters visible... that's to make it slightly more taxing for those of us who are good at anagrams.

(ever since I created this puzzle I have been trying to come up with another pair of words that I can use to make another. that's turning out to be a lot harder than it looks. it's easier to find two unrelated words that fit the grid - but I really want to keep the two words mutually clue-able, so they havce to fit the same theme.

I may have to rethink this variant just to make it possible to create more puzzles. I do like the idea of combining word skills with sudoku - hopefully I can come up with something along these lines in the near future. watch this space.)
