Small note on the instructions: The Tetromino Division sample puzzle uses 'S', while the list of tetrominos has 'Z'.

Interesting set of types, looking forward to this.

Nice set of puzzles. Looking forward to it.

I could not understand fully Torodial Slitherlinks. e.g. Where top left corner end is wrapping around? and how we are able to complete the loop?

It wraps around both ways. So the left most column of dots and the right most column of dots are really the same column. The same goes for the top most row of dots and the bottom most row of dots. From this we can also get that all corner dots are really the same dot.

Thanks for pointing this out. It has been fixed.

In Spirally as ABC should the order be A-B-C-D from the inside or from the outside?

According to the example in the IB it's from outside, which is also consistent with most spiral puzzles (put letters from outside).

Its from the outside (The open cell) to the inside, as the example shows.

For Tetromino Division, the Beginners' Contest authored by Serkan should be helpful - http://logicmastersindia.com/lmitests/?test=B2014032

Pentomino Division is basically the Pentominous from GMP - http://www.gmpuzzles.com/blog/?s=pentominous

Maximal Lengths was on the recent Puzzle GP - http://gp.worldpuzzle.org/content/wpf-puzzle-gp4 (Both Instruction Booklet example and the competition puzzle should be useful).

For some of the base types, me and Swaroop had collaborated for a practice set last year with some basic solving tips, which can be seen here - http://prasannaseshadri.wordpress.com/2013/07/03/ipc-preview-practi...

TomTom and Coded TomTom were both in IPC 2012, which is linked to in the opening post.

Hi All,

Nice puzzle :)
Thanks.

Good Puzzle Ravi. Thanks for sharing it.

Below is a link to a demo page. This demo page is mainly for newcomers who want to do a test run of how the system works for an online competition. You may check the different warning messages you will get for each answer key too.

In Battleship Observer, does a numbered cell count as empty cell for other numbered cells?

It will be counted as empty as clear from example (count numbers for 6 in example to understand and clear your doubt).

Yes.

Note: Pentominous doesn't have the restriction that each region can contain at most one letter, which the competition puzzle, Pentomino Division, does (as mentioned in the Instruction Booklet). Other than this, there's no change.

For the Tom Tom puzzle does operations division and subtractions apply if the group is having more than two cells? If yes, then I assume that operator will be applied in decreasing order.

Yes. And yes.

A little information about the authors -

Thomas Snyder and Grant Fikes are both from the USA, and are regular authors on Grandmaster Puzzles, where I am a contributing author too. You can find out more about them here and here. I have previously linked to some of the puzzles on this site, in this thread as practice, but you will find many other Classic puzzle types there too to practice for the weekend competition, like Nurikabe, Slitherlink, TomTom, Star Battle, Battleships, Araf, etc. I highly recommend the site for high quality puzzles in general.

Bram de Laat is from the Netherlands, and has a blog called Para's Puzzle Site. I have linked to a few puzzles that can be used from his blog too, but here too there are some great puzzles across a variety of types. There should be some helpful classics here too. Also, I recommend viewing the Slitherlink solving tips post by Bram, discussing patterns that are helpful in solving this puzzle type.

James McGowan is from New Zealand, but competes in the UK team internationally. He has been on "double duty" for this weekend, what with also being the main author for the UK Puzzle GP. He doesn't have his own blog, but has contributed puzzles to the UKPA forum, the German Puzzle Portal, and the upcoming Art of Puzzles book (by GM Puzzles). He's been quite helpful as one of the test solvers too.

There are contributions from the Organizers too, namely me and Deb Mohanty. Since you're already on LMI if you're reading this, Deb's basically the person who runs the site, and has also authored many contests here, including multiple National Championships. I have my own blog, but I'm not nearly as active as I used to be. My recent efforts, apart from writing puzzles for GM Puzzles and the recent Monthly Tests on LMI, have gone into starting a Patronage system for LMI. While the Championship is free, if you enjoy our contests, and want to give something back, please check it out.

Also, thanks to all the Test Solvers:

James McGowan, as mentioned above.
Bastien Vial-Jaime from France.
Vladimir Portugalov from Belarus.
Tiit Vunk from Estonia.

in Tiki Tour, can a tent belong to 2 trees? In other words, can 2 trees have only a single tent that is adjacent to both trees?

Each tree must have its "own" tent.

Word Nurikabe: Can the two or more given letters be part of same word? I assume that answer is yes as instructions does not restrict it. Please do clarify if possible.
