WarioWare D.I.Y. Showcase is a WiiWare video game that was released alongside WarioWare D.I.Y. on the Nintendo DS. It allows D.I.Y. owners to send their homeade mini-games wirelessly to the Wii, from there, games can be played on the Wii. Also the game will come pre-downloaded with 70 mini-games. The game will be available for 800 Nintendo Points.
The hosts of WarioWare D.I.Y. Showcase's mini games are different from those in WarioWare D.I.Y. and thus have different microgames to offer. Instead of 9-Volt, the Nintendo themed mini games are offered to the player by 18-Volt. Prior to starting 18-Volt's game blender, a small video plays showing a fictional video game starting up called Jet 18Volt by WariomanSoft. Following this, 18-Volt appears as a space ship and his microgames start arriving.
