E. Gadd's Contraption Conception is a game starring Professor E. Gadd, where the player is capable of creating their own inventions. The game is currently being developed by Amuza as an e-shop exclusive title for the Nintendo 3DS.

The game features similar gameplay to Banjo-Kazooie: Nuts & Bolts, where players create inventions and use them to solve puzzles to advance through the game.


E. Gadd's Contraption Conception is a puzzle-based game where players have to get from point A to B using gadgets created in the Gaddget Lab. Similar to Banjo-Kazooie's vehicle creation, players create their inventions using numerous different parts they collect from completing the different puzzles in the game.

The puzzles play similar to Mario and Donkey Kong: Minis on the Move in which the game takes place on top of a grid like area which contains obstacles, enemies and collectables, as well as a start and finish area.

In the Gaddget Lab, players can use different objects collected in puzzles to create gaddgets. There are three main types of gadgets createable; facial, handheld, backpack and footwear. E. Gadd can carry one of each type into a puzzle, meaning the player will have to analyze the puzzle board before entering the puzzle.


A series of paranormal events has found E. Gadd taking on the role of hero to rid the ghosts from their antics. The ghosts have been causing disturbances in numerous areas across the Mushroom Kingdom, and the only way to take them down is with E. Gadd's innovative inventions.
