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?

2R	1D	2D	2L	1L	1L	1L
1U	2R	2L	2D	1D	1R	2D
3R	5R	2D	2L	1R	1U	4D
2D	1R	2R	3L	2U	2D	1D
2U	1U	2D	1D	1L	1U	2L
6R	1U	4U	E	1D	3L	2L
2U	1U	2L	2L	1R	2L	6U

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

I recently went to the shop and purchased 4 items.

Three of the items cost:
$1.50
$3.00
$4.00

There was quite a long queue, and as I was quite bored, I was playing with my pocket calculator while I waited.

Very curiously, the 4 prices added to the same number as I got when I multiplied the 4 prices together.

What was the price of the 4^th item?

Home Improvements – Logic Puzzles

After a recent spate of home improvements, four couples were having a dinner party to discuss the additions to their houses.

Alan had not recently had a new bathroom. Kara had not yet done her kitchen, but perhaps would update it next. Brian, who is married to Maud, had not had new windows. Laura delighted in showing photographs of her new conservatory. Neither Charles nor David had a new kitchen. Julie had not had new windows. Alan, who also had not had windows, is not married to Laura and Charles is not married to Kara.
Who is married to whom, and what work had they recently undertaken, assuming that each couple had one improvement and no two couples had the same improvement.
