The games involve players using monkeys, armed with various tools, to pop as many "bloons" (balloons) as possible.
Mobile games based on the Bloons series are distributed through the App Store, Google Play, and some through Steam.
[1] Prior to working on Bloons, the pair had released Cash Sprint – a successful racing game that incorporated weekly prizes.
After the success of Cash Sprint, they developed their own web portal for flash games, but failed to gain the necessary traffic.
In all of the main games, the goal is for the player to clear the playing area of all Bloons (which, as implied, have similar traits to balloons) using a limited number of darts.
[5] The player is able to choose the power, aim, and other factors involving the launch of darts; and hence the path it will follow and what Bloons it will pop.
There is much strategy involved, especially since some Bloons have special powers or affect the player's darts in both helpful and hindering ways.
The game features all of the classic tower defense gameplay with a few enhanced strategies that add even more depth and challenge.
[10] The objective of the game is to move a super monkey that shoots a stream of darts to pop bloons.
The first game, Bloons Super Monkey, was released on Ninja Kiwi's website in February 2010.
It expands on the gameplay of the Bloons series with power-ups, merge mechanics, and a town building system.
2010 Wii: 21/100[20] Tech media website CNET reported favorably on the Bloons Tower Defense games for iPhone, describing it as having "nearly everything from the beloved Web-based classic".
The article reflects negatively on the controls, stating that "[they] are a little finicky", but overall their impression is positive, saying that the game is an ideal introduction to the tower defense genre for young children.
