Steer a single red blood cell around the circulatory loop, right order only, while your oxygen ticks down and the lungs are your only refill.
Was this fun?
How to play
Click the next chamber to route your blood cell along the circulatory path: right atrium, right ventricle, lungs, left atrium, left ventricle, body, and repeat. Only the next-in-sequence chamber is a legal move, a wrong turn bounces you all the way back to the lungs. Oxygen decays in real time and reloads at the lungs, so keep moving. Complete the required laps to win.
Only the glowing next chamber is a valid move.
Oxygen drains continuously; run out and the circuit fails.
Wrong turns cost you progress and points.
Controls
Desktop: click the glowing next chamber.
Phone & tablet: tap the next chamber, fully touch-friendly.
Game modes

Tips & strategy
Memorize the chamber order so you never hesitate over a wrong turn.
Time your run to hit the lungs before oxygen gets critical.
