About this game

Math problems are falling from the sky, and your dome is the only thing standing in their way. Solve each one, type the answer and launch a defense charge to blow it apart before it lands.

HOW IT WORKS
• Every falling block is a math problem. Type its answer on the keypad and hit LAUNCH.
• Correct answers score points. Wrong answers cost you shield.
• The longer you survive, the faster and longer the problems get, from a single 3 + 5 up to five-step chains.
• A boss arrives every 100 points, carrying a stack of problems you have to clear one by one.
• Reach 1500 points to face the final boss. Beat it to unlock Infinite Mode.

YOUR MATH, YOUR RULES
• Pick any mix of addition, subtraction, multiplication, division, exponents and roots.
• One- or two-digit numbers, decimals and negatives, switched on per operation.
• Turn on equations and solve for x: 3 + x = 8.
• Six starting difficulty levels, and a separate high score for every combination you play.

TOWERS AND TECH
• Build answer streaks to charge your towers: the Nuke Silo wipes the screen, the Chrono Tower slows time and holds back new enemies.
• Tesla Towers arc chain lightning through the enemy line whenever you solve an exponent or a root.
• Mines: every solved equation leaves a mine for the next enemy to hit.
• Spend upgrade points mid-run to strengthen your towers and armor, or to repair the dome.

RESEARCH LAB
Earn research cores across runs and spend them in a 16-node tech tree. Unlock four legendary intellects, Ada Lovelace, Lise Meitner, Albert Einstein and Nikola Tesla, each one changing how a run plays.

ALSO
• 15 achievements to earn
• A story that unfolds as you unlock new technology
• Tap UPGRADES at any time to pause exactly where you are
• No account, no sign-in and no in-app purchases. Free to play, supported by ads.

What’s new

- Albert Einstein research now powers up Chrono grenades: a stronger, longer slow-down.
