Puzzle 1
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?

Puzzle 2
This BrainBashers safe has a rather unusual control panel.
In order to open the safe, you have to press every single square once only, in the correct sequence, ending on the square marked E.
Each square indicates which square to press next, for example, 2U means move up 2 squares and 3R means move right 3 squares.
Can you determine which square you must start with?
