Solution to Puzzle 6

Start by sending two wolves across the river, resulting in:

WCCC.                           WW

You can then send one wolf back to the left bank:

WWCCC.                        W

Now, send the remaining two wolves to the right bank, which results in having all of the chickens on one side and all of the wolves on the other:

CCC.                               WWW

Send one wolf back, then move two chickens to the right:

WC.                                  WWCC

The next move (the sixth one) is to send a wolf and a chicken back, resulting in:

WWCC.                             WC

(This could also be achieved simply by sending a wolf and a chicken across in the first place, but the raft would be on the right bank, instead of on the left, as it is now.)

Next, move the two remaining chickens across:

WW.                                   WCCC

The remaining wolf can take the raft back across for the others:

WWW.                                 CCC

Now, it’s a simple matter to send two wolves across, send one back, and finally sending the other two wolves across in three more moves, resulting in eleven moves and:

                                             WWWCCC

Logic Puzzle 6

This is another Professor Layton puzzle,  from the first game, the Curious Village. This one was the first puzzle that I was stuck on, and it took me nearly an hour to actually solve it. In it, there are three wolves and three chickens which must cross a river.
 
“Get the three wolves and three chickens to the other side of the river while obeying the following conditions.
 
No more than two animals can ride the raft at the same time.
 
There must be at least one animal on the raft in order for it to move.
 
If more wolves than chickens stay on either side of the river, the wolves will eat the chickens, and you’ll have to start over.
 
You can move the raft as many times as you like, but this feat can be accomplished in as few as 11 moves.”

Solution to Puzzle 5

Your first instinct says,”If a dog-and-a-half eats a pound and a half in a day and a half, that means that a dog eats a pound in a day, and so a dog eats six pounds in six days, right?”

Actually, it means that a dog eats a pound in a day-and-a-half, so a dog really eats four pounds in six days.

Logic Puzzle 5

This is a puzzle I remember from a puzzle book I once read, and it is my favourite type of puzzle: simple at first glance, but then you find that that’s not all.

If a dog-and-a-half eats a pound and a half in a day and a half, then how much can one dog eat in six days?
