Ninja Kiwi, previously known as Kaiparasoft Ltd, is a New Zealand mobile and online video game developer founded on March 15th, 2006 by brothers Chris and Stephen Harris. Ninja Kiwi’s first game was a browser-based game called Cash Sprint, developed on the Adobe Flash Platform. Since then, they have produced more than 60 games across platforms including Adobe Flash, Android, iOS, PlayStation Portable, Nintendo DS, and more recently, Steam. Their most well-known titles are the Bloons and Bloons Tower Defense games. In 2012, Ninja Kiwi purchased Digital Goldfish, a Dundee, Scotland-based developer, for an undisclosed sum.

Ninja Kiwi has a virtual currency known as NK Coins; purchases of games and in-game purchases can be transacted using NK Coins. About eighteen months before its dissolution by its parent company, Mochi Media (another major gaming website) discontinued its virtual currency (Mochi Coins) and replaced it with Ninja Kiwi’s virtual currency.

Ninja Kiwi was acquired by Modern Times Group on March 24, 2021.
