This is the one hundred and tenth puzzle you will encounter in Professor Layton and the Unwound Future. To access this puzzle, you must examine the door. In order to solve this puzzle, you must press the buttons to set all the numbers to zero.


[edit] Hints

Hint One
    Notice that when a number reaches nine, it flips back to zero. In other words, the numbers are on a loop. So, push the buttons as many times as you like. It won't mess up anything.

    If you restart the puzzle several times and pay close attention to what each button does, the rules should become clear.

Hint Two
    The colored rectangle connected to each button shows which two squares it affects. When a button is tapped, the two numbers within its colored rectangle increase according to a hidden rule. Study the numbers one button at a time.

Hint Three
    Button A adds five.
    Button B adds three.

    The rules for buttons C and D shouldn't be hard to figure out now.

    But, even knowing the rules, how do you turn all the numbers to zero?

Super Hint
    Don't get too frustrated if you're still stuck. This puzzle is tricky.

    To solve it, don't tap the A button at all at first. Tap buttons C and D until the numbers in A's rectangle both read five. After that, you'll be able to solve it in no time.

Wonderful job!

Button A adds five, B adds three, C adds seven, and D adds four.

You must have worked that out. Unless you're one of those people that just kept pounding the buttons until they set everything to zero...

[edit] Step-By Step Solution

  • Tap the A button one time.
  • Tap the B button nine times.
  • Tap the C button seven times.
  • Tap the D button four times.
