Missing Number is a puzzle in Professor Layton and the Curious Village. For the puzzle in the European version of the game, go here.


The numbers below all follow a certain rule. What is the missing number?


Click a Tab to reveal the Hint.

As mentioned earlier, the numbers are lined up according to some rule or idea.

Continuing the string out to the left, the number that would go in front of the first number is zero.

The number that comes after the final three is one.

If you were to break up the string of numbers, the first group is "1231."

Does this group make you think of anything? Anything at all?

First, go ahead and count the large triangle all by itself. Then, add one of the three lines that splits the big triangle into two. Now your total has grown to three triangles.

Next, add one more line to your big triangle and you'll create three new triangles. There are three combinations of two lines possible.

Good luck finding the rest



Try again!

As mentioned before, the numbers are aligned according to a certain principle. Figure out the rule and the answer is in the bag.


Very good!

The string of numbers represents the dates from the end of one year to the beginning of the next!
