• Submit your first guess (for example - 2020).
• Check Era, Decade, Odd/Even, Last Digit and Last 2 Digits Diff attributes to see what matched (=) and what didn't (≠). Use these for deduction.
• Also check revealed color of your guess.
  If it's Red, guess a alphabetically lower name.
  If it's Blue, guess a alphabetically higher name.
  If first few letters are Green, those are correct starting letters. Guess another name that starts with the same green letters.
  Black and Gray letters provide no other clues.
  The exact match is found, alphabetically, between the "hot" (red) and "cold" (blue) clue names.

  Red is hot, go colder - move toward the beginning of the alphabet (towards A).

  Blue is cold, go warmer - move toward the end of the alphabet (towards Z).
• Refine your guess using revealed match clues.
• Repeat (until correct Year is identified).

• Choose a name from the matching names list. Then hit Submit button.
• If matching names list doesn't appear for the letters you typed, it indicates no matching name was found. In that case, please try a different spelling or another name. Our database is constantly growing; some names may be missing temporarily.

Here is a sample matching names list.

🥚 The Egg indicates you missed a previously revealed clue.

There is a max limit on how many Eggs you can have before you lose in each level. Try to make the most of the clues - avoid getting many Eggs. More Eggs you get, the lower your score, even if you win.

It could be either a name clue (color highlighted letters) or attribute match clue that you missed. For example, if first letter of the name you guessed is highlighted blue M and your next guess starts with G, then you'll get the Egg for this error. Blue letters are colder - you should move toward the end of the alphabet (towards Z) for next guess.

• Level 1 - Practice Level - max 7 Eggs
• Level 2 - Challenge Level - max 5 Eggs
• Level 3 - Precision level - max 3 Eggs
• Level 4 - Pro level - max 1 Egg
• Level 5 - Superpro Level - no Eggs

Customize the gameplay difficulty to challenge your brain. Warm up your memory with Practice Level. Switch to Challenge Level for a max score of 100 points. Superpro Level is the most difficult level - the game ends as soon as you miss any clue.
