Is the solution of Arrow Chess correct. I think the number 3 has a Bishop and 3 arrows pointing towards it..

Also, is it possible to explain Chessdoku even further. The digit 1 at the end of instuctions is not making much sense to me. Maybe I am being slow here!

About Chessdoku
Each chess piece can attack exactly two cells having 1 inside them.
Is that better?

For example : the knight attacks R3C5 and R6C2
the bishop attacks R1C1 and R2C4
so on...

Yes, it is a mistake. It should be 4.

The two 4s in the second row also seem to be not matching - should they be 5 each?

Sorry for bad example. It will be fixed. Most important is that the rules are clear.

I had a question on Hitori Chess.... in the example each chess piece attacks one number... however, can a piece attack 2 numbers in one line as in the example for Hidden Words... I am attaching an image of an alternate solution for Hitori chess.... Im not worried abt the dual solution of hitori chess in the example but want to confirm if the rule of hidden words (where the bishop attacks 2 Es in one line ) is also applicable in Hitori Chess.

In the attachment, one of the 4s in row3 has to be painted black. So it is not a valid solution.

As per rules, the example has more than one solution.

Please note that some of the examples are just for illustration purpose, and may not be valid puzzles by themselves. (Nikola mentioned this in IB )

Thanks, Rishi. Yes, we have a dual solution here but I'm glad that you understand the rules. As I said in booklet, this is not a puzzles.

In Battleships, can a piece attack the same ship more than once? (Say the knight attacks two cells of the 4-cell ship)

Yes..........I think so.........because the instruction

each chess piece attacks exactly one ship of every kind

It dosent talk about the number of ship segments.......

Now this was a completely new and refreshing set of puzzles :)

Though I am familiar with chess but never ever imagined an influx of chess into our normal day to day puzzles....

Great set Nikola... though not much to look forward to from my results point of view...

Great test !

Unfortunately I entered coordinates in alphabetical order instead of top to bottom for chess battleships and hidden words...
(I think the order required is not specified for hidden words.)

thanks for the puzzles
