Drop Chance

Drop chance is a determining factor in Growtopia. The drop chance [of a tree or item] is calculated based on how much fruit a single tree can drop. This is usually in multiples of four because a normal tree can display four fruit in its tree, but certain items (like the Legendary Wizard) have a drop chance of one.

It is used to determine if an item can be farmed or not. The higher the drop chance, the easier it is to farm it and earn gems or in-game experience. On average, backgrounds tend to have a higher drop chance than blocks, because backgrounds are generally needed in higher amounts than blocks when building a world.
