Twin flying discs are provided that include a first flying disc and a second flying disc separably fitted in the first flying disc. The first flying disc has a soft ring-shaped part and an intermediate cloth covering a central space of the ring-shaped part. The second flying disc has a soft ring-shaped part and an intermediate cloth covering a central space of the second ring-shaped part. The outer diameter of the second ring-shaped part is slightly smaller than the inner diameter of the first ring-shaped part, such that the second flying disc does not separate from the first flying disc until the combined discs are thrown in the air at a suitable speed.
