A Puzzle contest, but as a test-solver I can confirm that there will be something for the Sudoku solvers to attempt as well.

About April Contest

Please note this contest will have a slightly different format than regular LMI tests. The format will be same as last year's contest.

Key differences from regular LMI tests:

• The PB (Puzzle Booklet) will not have any password
• After the contest starts, you can download the pdf and start solving. Login at the contest page to start submitting.
• There is no time limit. You can submit until the contest ends.
• There will be some optimizer puzzles.
• Same scores will have same rank (i.e. early submissions do not count towards rank)

Hi. I have a query on the Fire puzzle. In the example, when time = 1 second, R3C3 is lighted. Will this flame lights up the match in R3C2 in N=1 or N=2. As per the example, it suggests N=2 but I am confirming whether a match will light up another match in the same second or next second.

If this second lights up the match in R3C3, the next second will light up cells R2C3 and R3C4.

Hi Riad, I want to ask you, whether all line segments which form the turn (in My Line - puzzle 4) have identical lenghts. In the example they have (number 3 and three ?).
Thanks in advance

a question on puzzle 1 fire

how many matches are lit at the beginning? Just one or may be more than one? does "some match" mean " a certain match" or "some matches"?

Hi Matus,
In each cell with a digit or "?" line turns. Segments comprising this corner have an identical length. In cells without digit or "?" where the line turning angle lengths may be different.

To clarify in puzzle 2 (Minefields), the numbers are treated as empty spaces, right? (And hence a numbered cell in the small grid doesn't have to correspond to a numbered cell in the large grid; it just needs to correspond to an empty cell in the large grid, numbered or not.) Otherwise there's an obvious contradiction. But clarifying...

And for puzzles 10 and 11, are the bounds M,N included? Or to be more explicit, take puzzle 10 (Loop Between the Polyominoes): is the maximum allowed grid size 26x26 or 27x27?

With my knowledge of English is hard to understand a question about Puzzle 2. I hope that Prasanna understand it and respond.

In Puzzle 10 the three maximum allowed grids are 26 x 26, 25 x 26, 26 x 25. M, N in puzzles 10 and 11 are not related.

I mean, can a number inside the small grid correspond to an empty space in the large grid or must it correspond to another number?

For My Line of Puzzle 4, does the reverse rule apply? In the sense, if the line makes a turn at a cell, should that cell definitely contain a number?

I answered a similar question from Matus:
In cells without digit or "?" where the line turning angle lengths may be different. But may also be identical.

In example pentominoes can be only into 4 x 4 area.

Then why does the last column contain 3 at the top when it is not part of the 4x4 area? What is the significance of that 3?
