Abstract: A play apparatus has a pair of devices. Each device has: a capture arrangement such as a cavity to capture an object such as a ball; an object detector to detect that the object has been captured; a transmission module to transmit a release signal; a receiver module to receive a release signal; and a release actuator to release the captured object. A first device detects capture of a first object, transmits a first release signal to cause a second device to release a second object. The first device withholds the first object until releasing it responsive to receipt of a second release signal indicating that another object has been captured by the second device.
