1. Battlesnake (6+6)

Firstly draw in the grid a snake, 45 cells long, not touching itself. Its head and tail are marked by gray cells. Then place full "Battleship" fl eet on it. Ships can not bend and touch each other. Ships of the same size can not follow each other. Every row and column of the grid must have at least one cell occupied by ship. Digits on top and left of the grid show number of cells occupied by snake in corresponding rows and columns, and digits at bootom and right show number of cells occupied by ships.

Answer

2. Seek and count (8)

There are 6 mathematic expressions with the same results. Each cell contains exactly one symbol (digit, operation sign and so on). Rectangles of one color hide the same fragments of expressions. Operation signs can not be in the neighbouring cells. Restore these expressions.

1         6     + 1

2 + 2     + 2     2

3     3     3  

4   - 4     + 2  

5   -     9     - 6

6     - 2  

Example:

1 . 5 * 4 + 4

1 . 2 * 1 0 - 2

3 * 5 0 - 1 4 0

Answer key: firstly write down the result of these expressions and then the fragments hidden behind the pink, green, blue and yellow rectangles in this order. For example the answer would be: 10: 1., 4, 0-.
