Hi, Bram.

Part 1: Domino Hunt

- Will the placement of the missing numbers in the grid be unique? So can the 2 missing numbers be the 4 and 5 in the [35] and [34] dominos, so you can't determine which one is the [35] and which one the [34], but you can still uniquely define how the dominoes lie.

The layout of the dominoes will be uniqueand the placement of the missing numbers will be unique.

Part 2:

Puzzle 7 Sum Star:

- Does each digit have to be used at least once?

There will be 9 empty circles in which you have to write numbers 1-9, each number once.

Puzzle 20 Black 21:

It says Shapes of 2 and 1 cannot touch. I assume that also means 2s can't touch other 2s and 1s can't touch other 1s, and not just that 2s and 1s can't touch eachother.

You're right, no two shapes can touch.

Puzzle 6 Marina:

- Will this puzzle be done with physical objects or with pencil?

- If they are physical objects, will they have a rectangular base? That way we can clearly see what cells are covered by the ships and be sure to know which cells are available for turning.

- Will there be more than one grid we can use?

- Will there be an easy way to keep track of our puzzle score as it's a pretty complex scoring process and we have to optimise our score?

This will be done with real objects, ''boats'' made of thin plastic. You are not allowed to draw anything on the grid.

The ''boats'' will look exactly like in the examples. They'll have their front corners cut to look like a ship's bow, but they are treated like rectangles, so be careful there. You'll have to watch out for those cells that look free but are in fact occupied.

Each team will get only one grid.

If you want to, you can count your score on a piece of paper, but that's not necessary, that's our job.

Part8:

Puzzle 9 Dominoes in Water:

- Will all O's and zeros look the same?

Yes, letters O and digits 0 will look the same.

Puzzle 12 Numbers and Letters:

- Will each row contain only one number or can it occur that we have to place more than one number per row?

- If more than one number, is the order they are written on the outside relevant?

- Also if more than one number, do they have to be seperated by an empty square or can they touch?

There'll be no surprises here, the puzzle will look like the one in the example, only with numbers 1-10 in 10 rows.

Puzzle 14 Count the Rectangles:

Will a Partial point answer still make you eligible for the time bonus?

No.

Part 11:

Puzzle 1 Domino Arrows:

- Will each domino be pointed at by an arrow? The wording says it can't be more than 1, but not necessarily imply that each domino is pointed at.

Each domino has to be pointed at.

You're welcome.
