Spot the Difference: Hints

• This hint slightly clues an aha moment. What do you notice in the grid of numbers?
• This hint clues an aha moment. Do you notice anything in the bottom row?
• This hint strongly clues an aha moment. This puzzle is a "number search".
• This hint strongly clues an aha moment. You're searching for well-known sequences of numbers.
• This hint strongly clues an aha moment. What numbers can you see in the grid that are part of well-known sequences of numbers?
• This hint strongly clues an aha moment. For the numbers given by the above hint, can you find a sequence in the grid they're in?
• This hint very strongly clues an aha moment. Can you almost find a sequence in the grid they're in?
• This hint gives away an aha moment. The grid contains six almost-sequences, that is, sequences with one item changed (different), as clued by the title and flavortext.
• These sequences are each six numbers long.
• How might we order these sequences? (Ordering is slightly helpful but in the end not that important.)
• These sequences each have a number changed in a different position.
• Order the sequences in order of the changed number's position, which is also alphabetical order of the sequence name.
• This hint slightly clues an aha moment. The next step is to get a number from each sequence.
• This hint clues an aha moment. No, the number you want from each sequence isn't simply the changed number (it's neither what it was changed from or what it was changed to).
• This hint clues an aha moment. Compare the numbers in the sequences that were changed to what they were changed to.
• This hint clues an aha moment. Note that the changes always increased the numbers.
• This hint strongly clues an aha moment. The title and flavortext can both be used again.
• This hint gives away an aha moment. Subtract the original changed number from the number it was changed to. This gives you six numbers.
• This hint suggests a method of doing research and can be skipped. Searching these six numbers should be helpful if you don't recognize them.
• The answer has four letters, as clued by the four blanks. That should resolve any ambiguity there might be about what the answer is.
