Isn't it supposed to be "Wood", not "Snow"?

No online solving

LMI's solving interface does not support some of the sudokus (e.g. Dragons, Eight Fit). To some extent, REALLY LATIN SQUARE will also be difficult to solve online with pencil marks overriding the given symbols.

So, online solving will not be available for this Sudoku test.

Well... you are right. That was the original idea

But the kanji (or hanzi, for chinese readers) for "wood, tree" is far too similar to "water" or "fire" and "earth" to a non-trained eye. This could have been a disadvantage for players who are not used to read ideograms.
So I decided myself for using a kanji that looks different in shape to the others.

Having test solved it, I think 88 minutes is suitable for this one.

Unfortunately, time constraints play a part in these things too. We will certainly consider enabling partial online solving in the future, but it's a bit too late to prepare it for this test. Please make do this time.

In the first puzzle it has said, that there are highlighted 3x3 regions and then it says puzzle number 2 and 3 contains digits from 1 to 8. Do we need to keep one cell empty, do we have to expect 2x4 boxes or can we expect the highlighted areas to be irregular?

2x4 boxes. Normal 8x8 Classic. You're right, the rules aren't completely clear in the IB. Missed that.

You can download either one.
"16 pages test" contains 1 puzzle every page.
"9 pages test" contains 2 puzzles every page, and it's meant to save paper printing at the cost of cell dimensions. Arrow+8 and Symbols puzzles anyway are on a single sheet.

WARNING: correction needed to contest puzzle n.16
If you are going to solve puzzle nr 16 before the file is updated, please bear in mind this change.
A symbol was missing in 2nd row, right side. This is the correct layout:

     What was your opinion of the booklet formatting and printing? I have a different complaint


    I think including a (bit-map based) logo in every page of the password protected booklet slows down the printing.

    It is better to have no additional frills in the passwod protected booklet, other than just the puzzles/instructions/points. After the test is over, we can put whatever else is desired.

    i)Can someone give me the start in the example puzzle for symbols?I am just not able to see the breakthrough.It looks as though the puzzle requires a combination of strategies and not just one to rely on.

    ii)In Really Latin square am i right in stating that the following are the conversions possible ? :
    1 - 1234678
    2 - 2378
    3 - 38
    4 - 4
    5 - 45678
    6 - 678
    7 - 78
    8 - 8
