About Heart Calcopus

The game puts arithmetic in bubbles and asks you to answer before the time runs out. The octopus reacts to what you get right, and a score counts what you managed. The numbers do all the talking, so there is nothing to read before you start.

This is a drill dressed as a game, and it is honest about that. The pressure comes from the clock rather than from the size of the numbers, so a run ends when you slow down. It runs at 800 by 600 in either orientation, and it works on a phone as well as on a desktop.

How to play

  1. Read the sum the octopus shows you.
  2. Pick the answer on screen before the timer empties.
  3. Keep answering to build the score.
  4. Start again and try to beat what you scored last time.

Tips

  • Do not stall on one sum. The clock, not the arithmetic, is what ends the run.
  • Play a second run straight after the first. The game is built around the score you left behind.
