The theme of part B is ...without regularly placed regions... but most of the example puzzles are 'regular' 2x3 blocks. How do I have to see this?
Thanks in advance!

Best regards, Richard

It is just a IB. We were not able to construct 28 original 8x8 puzzles for Instruction booklet. We believe, that for understanding the rules/instructions it is enough to have smaller puzzles in IB. And also, it is not possible to rotate half of the rectangles in 6x6 puzzle as in 8x8 puzzle (see the classics A1-2 and B1-2 in the IB).

No problem!
I just wondered if more grids would have irregular shapes than the presented puzzles in B1-2, B4, B5, B6, B11 and B12.
I know how much work it is preparing a test plus IB. Having no less than 28 puzzles (x2) isn't making this easier!
I am looking forward to the test, since 14 puzzles for a bit over an hour seems like that there are a few quickies to be done, even for a midrange-solver like me.

Richard, you´re absolutely right. Some of the puzzles will be easier (it is not hard to discover which ones), so that is why we even haven´t tought about bigger (harder) puzzles in IB. And of course, we want to keep the best puzzles for the competition.
All the irregular puzzles (as Irregular sudoku, Surplus-deficit or Irregular without regions) are irregular in IB. Only the usual variants, which will have rotated regions, are unrotated in the IB.

Dear puzzle friends,
in Foursome sudoku (A11-14) there are four sudoku grids and the points may be distributed for each grid independently. However we accept only solution, that is valid for all four puzzle grids together!
This sentence is missing in the IB, but we believe, that it was clear also before.

Thank you for understanding!

I think there's a typo in B8: the 8 on the right edge should be 3+5+1 = 9.

Looks like this will be a fun test!

In X sum sudoku: the clue is on the right puzzle at column 4. The number 8 is wrong. 9 is correct?

An updated version of IB is now available with this typo fixed.

Announcements - No Online Solving

LMI flash interface does not support Cube Sudoku. Also, it is very difficult to solve Irregular W/O borders on the flash.
So, it is decided that online solving will not be available in this test.

Wow, lots of fun puzzles, thanks!

I'm pleased that I turned one in with about 30 seconds left on the clock in part B. I hope I got it right.

One small correction, perhaps: It seemed like several times the input instructions said "row" when they meant "column" based on what was drawn on the paper.

I also didn't see the results page after I completed the test - table was blank. So I've no idea how many puzzles I solved correctly, and how many not. Well, I can see the results in 22-nd of May when I come back from China. Until then the excitement stays...
Puzzles were nice, except I didn't like pencilmarks so much. Probably, because I spent so much time on it:)

Is there something wrong with the order of results when people have the same total score? E.g: hunterkok is placed 56th, I am 57th, same total score, but I used less time (for both parts), so should the order not be reversed?

Same problem for Psyho vs caudmont (16th/17th), wielki_m vs takeya (41st/42nd) and agabum vs ThomasKostolany (49th/50th). I didn't look any further down the list.

Congratulations to Ulrich, Jan, Kota for topping in Sudoku 8X8. This is Ulrich's best rank (among the few Sudoku tests he has played) at LMI.

Of 235 players from 33 countries, 196 players got non-zero scores. Thank you everyone for participating. I hope everyone enjoyed the 8X8 Sudokus Matus and Zuzana presented.

Rohan, Tejal and Jaipal are the top 3 Indian performers.

Thanks for the test!
I enjoyed GT consecutive and X-sums the most. Even after solving some extra practice puzzles I was not too happy with my result. That is not caused by the puzzles, but by a too short night after a very nice rock-concert on saturday evening.

Incredible performances again by the top solvers! I hardly believed what I saw when I opened the score-page...
Congratulations to all top players!

Note to myself: When you play at the speed of a snail, when you do some mistakes somewhere in the 4 connected grids (so every code you send is wrong and you haven't time to start it again), when you send a code of a grid 2 times instead of sending the code of the grid you solved correctly and when, at the end of a round, you don't send the code of the grid you just solved correctly, thinking you have time to solve another one before the end of the round (and of course you don't have enough time to solve another),

you can not expect to make a good result !

Otherwise, it was an enjoyable test

I liked the idea of the X-sums sudoku very much so I have made two puzzles of this type for this weeks Friday-noon-puzzle at Logic Masters Germany. You can find them here: Easy 7x7 and Harder 9x9.

Have fun with these.
