Sonic the Hedgehog Spinball is a 1993 pinball video game developed by Sega Technical Institute and published by Sega.It is a spinoff of the Sonic the Hedgehog series set in the continuity of the Sonic the Hedgehog animated series. Players control Sonic the Hedgehog, who must stop Doctor Robotnik from enslaving the population in a giant pinball-like mechanism. The game is set in a series of pinball machine-like environments, and Sonic acts as a pinball for the majority of the game. Gameplay: Sonic Spinball is a pinball game in which the player controls Sonic the Hedgehog, who acts as the pinball. The majority of the game takes place within the “Pinball Defense System”, which resembles a series of large pinball machines. The game comprises four levels, each containing numerous flippers that can be used to aim Sonic’s trajectory and launch him through the level. Sonic can be maneuvered while airborne with input from the directional pad, which can be used for better positioning following an impact with a bumper or target or when Sonic is descending toward the drain, bumpers or flippers. The goal of each level is to collect all of the Chaos Emeralds and subsequently defeat the newly accessible boss located at the top of the level. Some Chaos Emeralds are blocked off by obstacles that require Sonic to hit certain switches or bumpers in order to create a clear path. The boss at the top of each level requires a specific strategy to defeat. A “status strip” at the top of the screen provides hints for defeating bosses as well as encouraging messages when the player makes progress. The strip also tells the player how many Chaos Emeralds are left to collect in a level. Following the defeat of an boss enemy, a bonus round is initiated.
