Note: Gardens larger than 6x6 do not exist in-game.
The Garden Calculator was originally made by Daydun and hosted at https://daydun.com/cookie/garden for the Garden minigame in Cookie Clicker. It was intended to be a way to test the efficiency of your Garden configurations by displaying the probabilities for plants to mutate in a given configuration.
It was upgraded by CursedSliver to include many new features and improvements; mainly for Garden Puzzles, but has also picked up on Daydun's unfinished agenda with the addition of features also helpful to ordinary players.
