Inflatable castles (also called closed inflatable trampolines (CITs), bouncing castles, bouncy houses, bounce houses, jumping castles, jumpers, bouncy castles, moon bounces, or moonwalks) are temporary
inflatable structures and buildings and similar items that are rented for functions, school and church festivals and

s and used for recreational purposes, particularly for children. The growth in the use of such devices has led to a rental industry that includes inflatable slides, obstacle courses, and games. Inflatables are ideal for portable amusements because they are easy to transport and store.
Inflatables have been marketed under several names, such as "Bounce House", "Bouncies", "Moon Bounce", "Boingalow", "Astrojump", "Moonwalk", "Jolly Jump", and "Spacewalk".
Inflatable castles have been suggested as having some therapeutic value for children with certain sensory impairments, similar to
ball pits.

, and the castle is inflated using an electric or petrol-powered
blower. The principle is one of constant leakage, meaning small punctures are not a problem – a medium-size "bouncy castle" requires a fan with a mechanical output of about two horsepower (about 1.5 kW) and consumes around 2 kW of electrical power, allowing for the efficiency of the motor.
UK and Australian bouncy castles have specifications calling for fully inflated walls on three sides with an open front and foam "crash mats" to catch children who may jump or fall out of the structure.
Modern moonwalks in the US are typically supported by inflatable columns and enclosed with netting. The netting allows for supervision as adults can see in from all sides.
Another type of home-use inflatable has evolved, with a blower pumping in air continuously. Pores in the seams and material allow air to escape as children play, while the blower continues to inflate the unit. This category has emerged as a response to parents who wish to buy an inflatable for home use.
Standards

In 2005, the most stringent standards in the construction of an inflatable amusement were adopted nationally in Australia, forming Federal Standard AS3533.4. This was a landmark safety standard bringing the toughest design/construction/operation standards to the inflatable industry of Australia. In 2006 the European Union (EU) followed and introduced similar standards throughout EU called EN14960:2006 which was then updated in 2013 to EN14960:2013.
While bouncy castle manufacturers adhere to voluntary standards, no national safety standards exist in the U.S., although some states such as Pennsylvania and New Jersey require that inflatables pass engineering and safety standards before allowing the equipment to be rented out. In 2017, roughly 25 U.S. states had regulations governing permits, inspections and insurance, although a private investigation by the Pew Charitable Trust has shown significant shortcomings by industry operators and regulators to do their part. North Carolina requires amusements rides, including inflatables, to be inspected annually by the North Carolina Department of Labor (NCDOL). For inflatables to pass inspection, operators in North Carolina are required to have all training records, a current certificate of insurance, and device manuals. Inflatables that are damaged and not safe will not pass inspection until they are repaired.
Inflatable obstacle courses

There are also inflatable obstacle courses that allow for participants to have races/sword fights and compete against one another. These are commonly rectangular in shape, but can also be square if the course is maze-like. Most obstacle courses have two lanes, but some can have three or four. They feature various such as pop-up obstacles, climbing areas, slides, and tunnels. These are the best choice for very large events since participants move through them quickly.
Inflatable park
The phrase "inflatable park" may refer to both a collection of portable inflatables set up temporarily as one attraction, or a permanent attraction consisting of inflatables.
Games
Some inflatables are designed to allow games such as boxing rings, water football, penalty shootouts, basketball, rumbling, tug of war, and gladiator duels. These interactive inflatable games are made out of the same material that a continuous airflow bounce house is made of. Quad tracks are also popular and provide the perimeter for
quad bike racing.
Safety
Injuries are common. According to Jim Barber, spokesman for the National Association of Amusement Ride Safety Officials, "It happens all the time. These are probably the most dangerous amusement devices they have. You see more injuries on inflatables than almost any other amusement ride you can think of – more than roller coasters." In 2010, "as many as 31 U.S. children per day were treated for injuries sustained in a bounce house, or one child every 46 minutes." An estimated 65,000 children under the age of 17 were injured from 1990 to 2010.

Injuries caused by inflatable rides were rising in the United States, according to a 2012 study published in the journal ''

report.
Frank Scurlock, son of inventor John Scurlock and manager of bouncy inflatable rental company Space Walk, ascribes the increase to rising non-commercial use of inexpensive retail 'backyard' units,
while bounce houses have also become more common overall.
Although rising, the number of injuries related to inflatable amusements is small when compared to the more everyday hazards of playgrounds and skateboards, which respectively were linked to an estimated 270,000 and 114,000 injuries in 2012.
In 2015, after studying the incidence of injury the commission released a revised bulletin for the recommended safety precautions for operating an inflatable device.
In a survey spanning 2003–2013, the most common injuries were fractures, strains, sprains, dislocations, contusions, abrasions, and lacerations. An estimated 88% of the injured were less than 15 years old.
Most injuries occur due to falls or collisions with another child. Some severe fall injuries occur after wind lifts bouncy castles skyward.
Incidents
From 2000 to early 2016, there were 64 bounce house accidents worldwide caused by wind, resulting in 271 injuries and 10 deaths.
Some more notable incidents have included:
* In South Yorkshire in England a boy died in August 2003 while using one, he had climbed onto the wall and fell out of the structure head-first.
* A boy's parents sued the hirers of a jumping castle in 2005 after he was given brain damage when another boy somersaulted onto him. An appeal was lodged, and the verdict was overturned.
* An eight-year-old girl died in May 2011 after falling head first from a bouncy castle onto a concrete pavement.
* In July 2015 two children were killed and three seriously injured when a gust of wind lifted a bouncy castle over 60 feet off the ground in Tartu county, Estonia.
* A seven-year-old girl was killed in England on 27 March 2016 after a sudden gust of wind lifted an inflatable bounce house into the air and carried it nearly a mile away.
* A six-year-old boy died in 2016 in Montevideo (Uruguay) after the bouncy castle was deflated with the child still inside.
* A child died in Girona (Spain) on May 7, 2017.
* A girl was thrown 20ft in the air from a bouncy castle on Gorleston beach, Norfolk, UK on 01 July 2018. She died of her injuries in hospital.
* In December 2021, six children died and three others were critically injured in a jumping castle
incident at the Hillcrest Primary School in
Devonport, Tasmania, Australia. According to witnesses, the children fell from a height of about after a large gust of wind blew the castle into the air. Jumping castles were banned from use by schools in Tasmania until further notice shortly after.
* Two girls, aged four and eight, were killed after a gust of wind lifted a jumping castle into the air in Mislata, Spain on 4 January 2022. The eight-year-old died the following day whereas the four-year-old died one week after the event.
