Puzzle 7 


Below is a very special grid, around each shaded number are 8 white squares.

However, each white square should have a number from 1 to 7.

Once filled in, these 8 numbers will sum to the shaded number.

In addition, once completed correctly, no row nor column will contain a duplicate number within a white square.

For example, the top row may be 5 6 4 2 3 1 7, etc.

This is a very difficult puzzle, and many people resort to using a computer to help them, which is a challenge in itself.

Puzzle 8 


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?

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