Puzzle 1
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 |
| 6U | E | 2U | 2L | 4L | 1L | 2U |

Puzzle 3
A woman had three old coins: a silver dollar, a quarter, and a dime. Each coin was a little battered and had a piece missing. She found that exactly the same fraction had broken away from each coin.
What fraction of each was missing if the value of the remaining bits of coins was now exactly one dollar in total?
For this puzzle it can be assumed that 1/2 a coin is worth 1/2 of its value.
Based on a puzzle by Henry Ernest Dudeney.
