It is part of Nintendo's Ultra toy series, which includes the Ultra Hand and the Ultra Scope. It launches soft balls that are to be hit with a bat. It sold over a million units. It was released elsewhere as the Slugger Mate.
Another version known as the Ultra Machine Deluxe was released in 1977.
The Ultra Machine appears in both WarioWare, Inc.: Mega Microgame$! for the Game Boy Advance and WarioWare: Smooth Moves for the Wii, as a boss fight in the former and a regular microgame in the latter. It appears in some Mario Party games such as Mario Party 5. It also makes an appearance as a piece of furniture in Animal Crossing: New Leaf for 3DS. The Ultra Machine also makes a major appearance in the 3DS game Rusty's Real Deal Baseball. The game features characters with Ultra Machine shaped heads, and, in a few instances, flat out Ultra Machines. In Splatoon 2 for the Nintendo Switch, the Bomb Rush special weapon also resembles the Ultra Machine.
