Puzzle 1
Fill in the missing numbers with the digits 1 to 9. A diamond shape in the middle means that the four numbers around it add to 20.
Each uses a different way to add to 20, if there is already 1 + 3 + 7 + 9, then there will not be another using the digits 1, 3, 7 and 9 (in any order).
The same digit isn't allowed to touch, even diagonally.

Puzzle 3
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?
| 4R | 4D | 1R | 1D | 2D | 4L | 1D |
| 1R | 4D | 5D | 2R | 2D | 1L | 4L |
| 2R | 1D | 1L | 2R | 2R | 2D | 2U |
| 2R | 2R | 3U | 3D | 1R | 3U | 6L |
| 3U | 3R | 1D | 2U | 4L | 2D | 3L |
| 3U | 1L | 1R | 1R | 1R | 1R | 2U |
