Puzzle 7
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?
| 3R | 4R | 2R | 2D | 2R | 4D | 2D |
| 2R | 1U | 1U | 3D | 2D | 1R | 2L |
| 3D | 1D | 3R | 1R | 2L | 4L | 1D |
| 1U | 4R | 2L | 3D | 2D | 2L | 4L |
| 4U | 1L | 2D | E | 2R | 1D | 4L |
| 1R | 1D | 1R | 4U | 2R | 3L | 1D |
| 5U | 5U | 2L | 2R | 2U | 5U | 2L |

Puzzle 8
The river Pregel ran through the town of Konigsberg. In the river were two islands, connected to each other and the rest of the city by seven bridges.
The residents of Konigsberg challenged each other to walk through the city, and cross each of the seven bridges exactly once.
Can you find a path that they might have taken?
This is the 'Seven Bridges of Konigsberg' puzzle, tackled by Leonhard Euler in 1736.
