You may have noticed that the second most played game on Steam right now is Banana, which was released in April but has seen an explosion of popularity in recent weeks. What is banana? It’s a free idle clicker in which you click on an image of a banana to increase the numbers. If the number increases enough, the game will place additional images of bananas in your Steam inventory. Actually, it’s not even an idle clicker; simply leaving the game open all day is enough to generate a slow but steady supply of these banana pictures.
