How to play

  • Click Start, then tune Kp, Ki, Kd to keep the water between the underfill line and the top.
  • If you overflow, it spills and you lose. If you drop below the underfill line, you lose.
  • You ONLY earn points when within the cyan scoring zone (±5% of setpoint).
  • Smooth, precise control wins - wild oscillation means no points!
