The invention provides an entertainment device with multiple circulating rails. The device comprises a rail adjusting mechanism and adjustable rails; the rail adjusting mechanism is composed of sevensub-adjusting mechanisms. The seven sub-adjusting mechanisms are a stepped ascending mechanism, a gravity type rail separation mechanism, a comb-shaped tooth translation type ascending mechanism, a crank rocker type ascending mechanism, a magnet attraction type ascending mechanism, a photoelectric door type rail separation mechanism and a chain wheel type rail separation mechanism; the seven sub-adjusting mechanisms are each provided with a material inlet A and a material outlet B, and the material inlets A and the material outlets B in the seven sub-adjusting mechanisms can be freely fitted and connected through the adjustable rails. The seven sub-adjusting mechanisms are used for independently adjusting the motion path, so that the whole rail has diversified motion paths, and the interestingness and practicability of the device are improved.
