A puzzle based on physics processes, Carnot Game invites you to realize something that does not exist in nature. All processes in nature are irreversible. The river cannot flow back, the flower cannot become a sprout or a seed again. Likewise, the so-called Carnot cycle is not feasible, although scientists are striving for it. The point of the cycle is to achieve a reversible process. That is, heat turns into work and vice versa. Your job is to achieve the maximum value by adjusting the heat and cold that will raise the piston or slow down the lift in Carnot Game.
