Sport stacking, also known as cup stacking or speed stacking, is an individual and team game that involves stacking and unstacking plastic cups in sequences as fast as possible.
Sequences are usually in the form of pyramids, and players compete against the clock or another player or team.
TERMINOLOGY
Upstack: The cups are stacked "up" into pyramids.
Downstack: The cups are put "down" into columns.
Fumble: One or more cups fall.
RULES
Both hands must be on the touch pads on the timer mat before stacking. The timer starts once one or both hands are removed. The timer stops when both hands are back on the touch pads. During a fumble, the stacker should restack the fallen cups before continuing with the next stack.

NON-COMPETITIVE SEQUENCES

Mini Cup Stacking: Typically with the same sequence as competitive stacking, but using mini cups, which requires a higher level of fine motor skill.
