In fact, if we left out the above mentioned 5 puzzles, then there are 8 newer variants in this test. If the solution of 1 puzzle is posted everyday, then we would be able to finish this by 2nd July (well before when the test begins)


Are you thinking about something like this?

Can't we do it like this.

Is it because we want to find out the no. of turns by the loop

Aditya, If we allow the red lines as you have shown, there will be 2 loops. (one small loop and another big loop)
That is not allowed. As per the instruction "Draw a single continuous loop that visits all dots. ....."

The answer key is "The number of turns made by the loop" - That has got nothing to do with what the solution should be. [ The answer key will never govern what the solution should be. Since we don't have mechanism to solve the puzzles online, we have to rely on answer keys like many other online puzzle contests]

Oh, thanks for clarification.

It didn't cross my mind, that in this scenario, two loops are formed.

Start9 at R2C3 can't be black. If it is black
R1C3 and R3C3 both will be white,
but both are 9
Only one 9 possible in Row2 and Col3Blacks don't touch each other
2 at R2C4 is white, else 9 at R2C3
will be closed. [ All the whites must
be connected to each other orthogonally].
2 at R2C5 becomes black		Blacks don't touch each other
4 at R1C1 and 7 at R3C1 has to be
white, else 5 at R1C2 can't connect
to other whites.		7 at R4C1 becomes black.
3 at R4C2 becomes white
3 at R4C5 becomes black.
5 At R5C5 becomes white.		5 At R5C3 becomes white.

Domino solution steps attached.

Note that the examples for Domino and Arrows are actually little difficult.

Neeraj,
The arrows example is tough and needs T&E.
We've replaced with an easier example. Download the updated IB. You should be able to solve it with ease.

Notes about Puzzle Booklet

  • The Puzzle Booklet does not have the examples.
    So, if you want to refer to the examples while solving, please keep a printed copy of the IB handy

  • The Puzzle Booklet has the instructions for puzzles, but it does not have the instructions for answer key.
    Instruction for answer key is available in the IB and also in the website for submission

  • The puzzles are numbered for 01-25 in the Puzzle Booklet and also in the submission website. This will help you submit puzzles in any order you need.

  • The puzzles will be in green color - if that distracts you, please print in b/w printer :-)

    More examples can be found at Rohan's blog - http://rohanrao.blogspot.com/2010/07/indian-puzzle-championship-jul...
    Rohan has nicely organized it for the EverGreens.

    It is little late, but still better than never.
    Thanks Rohan!

    Players can check their scores 100 minutes after they start the test.
    As per a suggestion somewhere else in forum, players can see their own score - and not others.
    If someone finds problems with their score, please report here.
    Don't post answers - just post the Puzzle and your id.

    After the Test is over, full results will be available.

    Battleships: It is not required anywhere that the answer should be in alphabetical order (** e.g.), and a reverse order (**) has been judged incorrect (**-* for me).

    Marked 50 for P06. Check your answer for P05, you have typed same co-ordinates twice. Bad typing mistake.
