Matching Pairs
Is it allowed that the pairs overlap, i.e., that one shape is used for more than one pair?

Maze View
In the example, does the empty block at the front right carry information? I.e., would A7 also have been the correct solution if A6 was black?

Two Clocks
Seems to me that in the example, the second display could also have minutes 0,3 or 3,6 or 5,8 or 6,9, right?

Yes, it is possible. Tasks 4, 5, and 6 are three independent tasks that just share the same collection of objects.

No, in this case it would not be the correct solution.

The view includes the blocks to the person's immediate left and right. I.e., if there is no block shown immediately to the left/right of the cell with question marks, the next cell in that direction is empty.

Yes, you are right, but please note that it is enough to express the difference, not the exact times.

Puzzle 10. Moving matches
a) There is no digit 0 in th list. Is this digit prohibitet?
b) Is a spaces between digits fixed? For exampl is it possible to convert 515 to 551 by miving 1 tp the right. Or convert 0 to 111?
c) Can we use power operation? In the example 72 can be convertet to 7^5. Is this correct solution?

Puzzle 15. Word search
Can we change the direction while reading the word?

1 cryptarithm: are the numbers expressed in base 10, I suppose?

This was just an oversight, the digit 0 is allowed. (The text already says "ten decimal digits".) This will be fixed.

No, you must not create a completely empty space inbetween the digits. Changing "515" into "5 51" is not a valid solution.
Yes, changing "0" into "111" is allowed (but note that this requires moving four matches).

AndreyBogdanov wrote:c) Can we use power operation? In the example 72 can be convertet to 7^5. Is this correct solution?

Obviously no, as this would have been a better solution to the provided example. The result must be a plain number written in base 10, with no mathematical operators, whether they are explicit or implicit.

AndreyBogdanov wrote:Puzzle 15. Word search

No (see example). This is a standard word search. Each occurrence is formed by five consecutive letters going in one of the eight standard directions.

6. MATCHING PAIRS
My teammates would like to know the definition of "vertices" in this puzzle.
(For example, is it allowed that more than two vertices are placed on single line?)
