Puzzle 3 


Below is a map of the BrainBashers detention facility.

There are 9 guards, A to I, who are in charge of a particular number of cells.

The guards only guard cells that they can see in a continuous straight line, either horizontally or vertically, and each cell is only protected by one guard.

The numbers represent how many cells each guard is in charge of, they are of course in charge of the cell they are currently in.

Can you work out which guards are in charge of which cells?

Note: this puzzle is not interactive, and the squares cannot be clicked.

Puzzle 4 


During the recent BrainBashers cipher convention, a binary code contest took place.

The contest consisted of a binary code transmission where the spaces between the letters were missing and there was no punctuation.

Each letter of the alphabet was translated into its binary equivalent based on its position in the alphabet. The resulting code was then blocked in groups of five digits.
a=1, b=10, c=11, d=100, e=101, f=110, g=111, h=1000, i=1001, j=1010, k=1011, l=1100, m=1101, n=1110, o=1111, p=10000, q=10001, r=10010, s=10011, t=10100, u=10101, v=10110, w=10111, x=11000, y=11001, z=11010

Can you find 10 countries?
