About Heart Calcopus

Heart Calcopus is an underwater educational math puzzle game led by a friendly octopus. Floating sea bubbles containing numbers and basic arithmetic operators (addition, subtraction, multiplication) float across the screen. Players must quickly select correct number combinations to solve target equations displayed on the octopus's shell before bubbles pop.

How to play

On desktop, left-click on bubble numbers in sequence to complete target math equations. On mobile devices, tap number bubbles directly on screen. Correct solutions earn heart points and extend your game timer. Beginners fail by panicking when bubbles speed up, making mental calculation errors on simple subtraction.

Tips

  • **Solve High Operators First:** Complete multiplication bubbles first to drastically lower remaining equation target numbers.
  • **Watch Bubble Speed:** Clear fast-rising bubbles near the top screen edge before they pop and dock timer penalties.
  • **Use Hint Pearl Boosters:** Click pearl icons when stuck on complex multi-bubble equations to highlight correct starting pairs.
