Element challenges fall from the top of the screen. Type the correct answer — element symbol, atomic number, group, or period — before they reach the bottom to destroy them and survive!

Auto-Targeting: The game automatically targets the element closest to the bottom. A laser pointer shows which one you are solving.

Type the Answer: Look at the challenge and type only the missing part (the __ blank). Your input appears at the bottom of the screen.

Case Matters for Symbols: Element symbols use standard notation — Fe not fe or FE.

Combos: Solve challenges in a row without mistakes to build combos. Higher combos = more points!

EPM: Elements Per Minute measures your identification speed.

Powerups: Destroyed challenges may drop powerups like Shield, Slow Time, 2x Score, Bomb, Heal, and Freeze.

Every 5 waves, a boss element appears with 3 HP. You must answer it three times to destroy it. Each correct answer deals 1 damage.

Easy (H → Ca): Elements 1–20 — hydrogen, helium, carbon, oxygen, common metals

Normal (Sc → Xe): Elements 21–54 — transition metals, Iron, Copper, Silver and more

Hard (Cs → Rn): Elements 55–86 — period 6, lanthanides, Gold, Mercury, Lead

Insane (Fr → Og): Elements 87–118 — radioactive, synthetic, actinides, transactinides

• Type faster to build higher combos

• Focus on the element closest to the bottom (auto-targeted)

• Use powerups strategically to survive longer

• Learn the periodic table groups to predict harder elements

• Laser pointer shows which challenge you are solving

• Backspace clears your current input
