The invention provides a suspended projection game and study system. The suspended projection game and study system comprises a suspended projection device, an input unit used for presenting one or more instruction content, and an electronic device with a screen, wherein the suspended projection device comprises a placement board with an opening, at least one projection refractor and at least one support positioning part, therefore, when the electronic device is placed on the placement board of the suspended projection device, since a capture module of the electronic device can capture the instruction content provided by the input unit and transmits the instruction content to an application module, the application module judges the received instruction content, and at least one three-dimensional image is displayed on the screen; the three-dimensional image displayed by the screen of the electronic device can irradiate a projection refraction plate of the projection refractor through the opening of the placement board, then the three-dimensional image is subjected to the outward projection imaging through the projection refraction plate, and therefore, with the system, the three-dimensional image content is closely combined with the game process of a tabletop game, and thus the interestingness of the game is improved.
