The Carnot Game is an engaging experience centered around the Carnot Cycle, in which the participant needs to shift among three thermal sources (hot, insulator, and cold) to optimize the work performed on the piston within a cylinder. The objective is to maintain the piston functioning in the perfect Carnot cycle, executing the transitions between sources at appropriate intervals to prevent the cylinder from either bursting or freezing. The nearer the player is to the Carnot cycle, the greater their score and advancement.

The participant is required to click the button to toggle between the thermal sources of the apparatus, ensuring they make the transitions at the correct times to circumvent the piston becoming stuck or the cylinder detonating. The Carnot cycle comprises four thermodynamic processes.
