+A stack refers to [hit objects](/wiki/Hit_Objects) that [overlap](/wiki/Mapping_Techniques/Overlap) each other in the playfield. The most common object that is stacked are hit circles.

+Stacks are automatically created when hit objects are close to perfectly overlaping each other. The time between objects for this to occur is determined by stack leniency.
