Juggling practice has developed a wide range of patterns and forms which involve different types of manipulation, different props, numbers of props, and numbers of jugglers. The forms of juggling shown here are practiced by amateur, non-performing, hobby jugglers as well as by professional jugglers. The variations of juggling shown here are extensive but not exhaustive as juggling practice develops and creates new patterns on a regular basis. Jugglers do not consciously isolate their juggling into one of the categories shown; instead most jugglers will practice two or more forms, combining the varieties of juggling practice. Some forms are commonly mixed, for example: numbers and patterns with balls; while others are rarely mixed, for example: contact numbers passing. Many Western jugglers also practice other forms of object manipulation, such as diabolo, devil sticks, cigar box manipulation, fire-spinning, contact juggling, hat manipulation, poi, staff-spinning, balancing tricks, bar flair and general circus skills.
Toss juggling is the form of juggling which is most recognisable as 'juggling'. Objects, typically balls, clubs or rings, are repeatedly thrown and caught in a variety of different patterns and styles.
The term "toss juggling" is only used by a very small subset of jugglers to distinguish between "pure juggling" (throwing and catching juggling) and the wider range of circus skills usually associated with the term "juggling" like diabolo, devilstick, cigar boxes and more.
For the purposes of record keeping and ease of communication, the terms balls and beanbags are generally interchangeable in the juggling world.
Numbers juggling is the art and sport of keeping as many objects aloft as possible. 7 or more balls or rings, or 5 or more clubs is generally considered the threshold for numbers. Traditionally, the goal has been to "qualify" a number, that is, to get the pattern around twice such that each object has been thrown and caught twice. A newer generation of jugglers tends to value a "flash", which is to throw and catch each object only once. Since a flash is much less difficult than a qualifying run, there will be numbers flashed but not yet juggled. For example, the current world records are: Balls/Beanbags − 11 qualified, 13 flashed; Rings − 10 qualified, 13 flashed; and Clubs/Sticks − 8 clubs qualified, 9 sticks flashed, 9 clubs flashed.
