• Pick a Periodic Table Element Card that you think is NOT the smallest Periodic Table Element and click it.
• If guessed item is highlighted as green (=), it's the correct elimina8ion. Make the next elimina8ion.
• Repeat (until all but last item are elimina8ed).
• 🥚 The Egg indicates you missed a previous clue. Avoid getting many Eggs. Up to 7 Eggs (clue errors) are allowed in Practice Level, 5 Eggs in Challenge Level and no Eggs in Superpro Level.
• A red open envelope indicates you lost. The game ends as soon as you pick the smallest Periodic Table Element, which is a wrong pick.

🥚 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.
