List of WarioWare: D.I.Y. contests

Design Challenges
Periodically, Nintendo holds design challenges, also known as contests, where WarioWare: D.I.Y. owners can send in their game creations that have to comply with certain conditions depending on the challenge. Players who want to take part in the challenge need to access the Nintendo Wi-Fi Connection. One person can enter one time each. Games of the challenge winners will be made available under the category Theme Games for download over the Wi-Fi Connection by Nintendo for a limited time.

The first design challenge was started by Nintendo with the Japanese release of WarioWare: D.I.Y. The challenges differ between regions.
