Puzzle 17 



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.

Puzzle 19 



Complete this grid with the digits 1 to 6 to make the sum correct.

Perform each mathematical operation in the order shown, from left to right, so 1 + 2 x 3 is treated as (1 + 2) x 3 = 9.

Consecutive numbers are not next to each other, there is no ÷ 1, and at no point is a decimal or a fraction used.

?+?-?x?/?x?=50
Note: this puzzle is not interactive, and the squares cannot be clicked.

Alex's Dogs - Logic Puzzles

Alex is a keen dog admirer and over the years has had a number of dogs.

Alex has had an Alsatian, a Dalmatian, a Poodle, and a Great Dane, but not necessarily in that order.

Alex had Jamie first. The Dalmatian was an adored pet before the Great Dane. Sammy, the Alsatian, was the second dog Alex loved. Whitney was owned before the Poodle. Jimmy was not a Great Dane.
Can you match the dogs to their names and find the order in which Alex had them?
