Bloons

The Bloons series is the original grouping of games developed under the "Bloons" name. 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 are many sequels and spin-offs of this series, with large fan support (indicated by the "player packs" discussed later).

Bloons Tower Defense

In the Bloons Tower Defense series (often abbreviated Bloons TD or BTD), the main objective of the game is to pop the enemy Bloons before they reach the end of the path on the game screen. The player has various types of towers available to defend against the Bloons, such as Dart Monkeys, Tack Shooters, and the powerful Super Monkey.^[6][7] There are also other types of towers introduced in later editions of the series, such as Ninja Monkeys and Monkey Buccaneers, the latter of which could only be placed on water. Every tower can be purchased and upgraded with in-game money which is earned through various means.

There are many types of Bloons, the Red Bloon being the weakest; the tougher variants each contain one or more weaker ones, released when the containing Bloon is popped.^[8] For example, the Green Bloon contains a Blue Bloon, which contains a Red Bloon. Depending on the difficulty and version of the game, the player has a certain number of "lives" available. Different types of Bloons consume different numbers of lives if they escape, based on the total number of Bloons contained inside. Some Bloons have special attributes. Lead Bloons are immune to sharp things, black Bloons are immune to bombs, and white Bloons are immune to ice. There are special types of Bloons such as the infamous "MOAB-class" (Massive Ornary Air Blimp, sometimes called "Mother Of All Bloons" although that is incorrect according to NinjaKiwi^{[citation needed]}) where the Bloon resembles an airship and takes many hits to defeat, an example being the ZOMG or BFB (Zeppelin Of Mighty Gargantuanness or Brutal Floating Behemoth). In general, the newer games have had more Bloon and tower types.

Bloons TD6 is the latest installment in the main Bloons Tower Defense series, but Bloons Tower Defense Battles 2, a spinoff, is the most recent game overall. Both have a variety of new and improved features. The game features all of the classic tower defense gameplay with a few enhanced strategies that add even more depth and challenge.

Bloons Super Monkey

Bloons Super Monkey (often abbreviated as BSM) is the second Bloons spin-off series to date; it is a bullet hell RPG with three installations so far.^[10]

The objective of the game is to move a super monkey that shoots a stream of darts to pop bloons.^[11] Popping them gives the player power blops, which are used to buy upgrades. If the monkey fails to pop the required amount of bloons for a certain level, the game is over. The super monkey wields weapons, which can be upgraded or replaced with a different weapon.

The first game, Bloons Super Monkey, was released on Ninja Kiwi's website in February 2010.^[12] In May 2013, a sequel, Bloons Super Monkey 2, was released on the same website.^[13] In November 2016, a refined version of Bloons Super Monkey 2 was released on the iOS App Store and Android Play Store for download.^[14]

Bloons Pop!

Bloons Pop! is a spin-off mobile game of the main Bloons series that incorporates elements of the Bloons TD series, mainly Bloons TD6, with puzzle gameplay. It expands on the gameplay of the Bloons series with power-ups, merge mechanics, and a town building system.^[15]
