Contraptions 3 is a casual indie puzzle game from Moragami Co., Ltd. Players solve over 200 physics-based puzzles across five distinct worlds by fixing broken Rube Goldberg-style contraptions. The objective is to set up chain reactions using a variety of goofy gadgets to eliminate monsters on each level.The game allows players to create and share their own levels, fostering replayability. Gadgets range from simple items like scissors to complex machines like fireworks-powered conveyor belts, all affected by physics. Solutions can be achieved in multiple creative ways, encouraging experimentation with chain reactions, such as using a rocket to pull a rope that triggers a laser gun.
