Too Many Mice is a puzzle in Professor Layton and the Curious Village.


Mice are famous for their ability to multiply at breakneck speeds. The type of mouse we have here gives birth once a month, birthing 12 babies each time. Baby mice mature and can give birth two months after they are born.

You picked up one of these darling baby mice at the pet shop and brought it home the day after it was born. In 10 months from now, how many mice will you have?

You may be thinking there's going to be a lot of bothersome calculation involved in solving this puzzle, but you don't need to do anything complicated to find the answer.
Read the problem over carefully.

Do you remember how many mice you started with? Have you considered how many mice you can expect, given that number?

OK, let me spell it out for you. You need your mouse to become pregnant before it will give birth. What does the mouse need in order to become pregnant?



Too bad!

Take a deep breath and think about it. That may not seem like much help, but you can do it.


That's right!

Your mouse can't birth any babies by itself!
