The game was initially developed as a [[wikipedia:Browser_game|browser game]], built upon the [[wikipedia:Adobe_Flash|Adobe Flash]]<!--many of the Bloons TD games are still playable on Adobe Flash emulators--> [[wikipedia:Computing_platform|platform]] and released in mid 2007. Later games in the series expanded to support various mobile platforms, including [[wikipedia:Android_(operating_system)|Android]], [[wikipedia:IOS|iOS]], [[wikipedia:Windows_Phone|Windows Phone]], [[wikipedia:PlayStation_Portable|PlayStation Portable]], [[wikipedia:Nintendo_DSi|Nintendo DSi]], [[wikipedia:Microsoft_Windows|Windows]], [[wikipedia:Linux|Linux]] and [[wikipedia:MacOS|MacOS]]. Games in the ''Bloons'' series older than ''Bloons TD 6'' are available through the Ninja Kiwi Archive on Steam.

In the game, players attempt to prevent Bloons (the in-game name for [[wikipedia:Balloon|balloons]]) from reaching the end of a set course by placing towers or road items along it that can pop the bloons in a variety of ways, typically by using the power of monkeys. A handful of towers can stall the bloons and give the other towers more time to pop them by freezing and gluing the bloons. Money is gained by popping bloons, completing rounds, and collecting bananas from existing banana farms which can be spent on new towers, upgrades for existing ones, or temporary items such as exploding pineapples and road spikes.

== Gameplay ==
The main objective of ''Bloons TD'' is to prevent Bloons (in-game name for [[wikipedia:Balloon|balloons]]) from reaching the end of a defined track on a map that consists of one or more entrances and exits for the bloons.<ref name="wired-btd4mobile-review">{{Cite magazine|url=https://www.wired.com/2011/03/bloons-td-4-iphone-review/|title=Review: Armed Monkeys Pop Deadly Latex in iPhone Bloons 4|magazine=Wired|via=www.wired.com}}</ref> The game is a [[wikipedia:Tower_defense|tower defense]] game and thus the player can choose various types of towers and traps to place around the track in order to defend against the bloons, gaining 1 in-game dollar for every layer of bloon popped.<ref>{{cite web|url=http://www.pcwelt.de/news/Bloons-TD-257959.html|archive-url=https://web.archive.org/web/20120301232330/http://www.pcwelt.de/news/Bloons-TD-257959.html|archive-date=March 1, 2012|title=Bloons TD|date=August 23, 2007|work=PC Welt|language=de|access-date=January 27, 2010}}</ref><ref name="PG2">{{cite web|url=http://www.pocketgamer.co.uk/r/PSP/Bloons+TD/news.asp?c=21718|archive-url=https://web.archive.org/web/20140102192307/http://www.pocketgamer.co.uk/r/PSP/Bloons+TD/news.asp?c=21718|archive-date=January 2, 2014|title=Bloons TD coming to PSP Minis|date=June 24, 2010|access-date=January 1, 2014|first=Jon|last=Jordan|work=Pocket Gamer|url-status=dead}}</ref> If a bloon reaches the end of a path, the player loses lives (or in later games, health); once these are all depleted, the game ends.<ref name="ASTD4">{{cite web|url=http://www.appspy.com/review/4080/bloons-td-4|archive-url=https://web.archive.org/web/20140102192746/http://www.appspy.com/review/4080/bloons-td-4|archive-date=January 2, 2014|title=Bloons TD 4 Review|date=January 6, 2011|access-date=January 1, 2014|first=Andrew|last=Nesvadba|work=App Spy}}</ref><ref name="STP">{{cite web|url=http://www.slidetoplay.com/review/bloons-tower-defense-review/|archive-url=https://web.archive.org/web/20140102195839/http://www.slidetoplay.com/review/bloons-tower-defense-review/|archive-date=January 2, 2014|title=Bloons Tower Defense Review|date=October 21, 2009|access-date=January 1, 2014|first=Tim|last=Rattray|work=Slide to Play}}</ref> The bloons always follow the map's set path on the track until they either reach the exit(s), are popped, or are moved to an earlier part of the track by a tower's ability.

There are three classes of bloons in the game: regular (unnamed in the game), MOAB-class and Boss-class. As of ''Bloons TD 6'', the regular bloons consist of: red, blue, green, yellow, pink, black, white, lead, zebra, rainbow, purple, and ceramic bloons. MOAB-class bloons are in the shape of a blimp and consist of: the MOAB (Massive Ornary Air Blimp), the BFB (Brutal Flying Behemoth), the DDT (Dark Dirigible Titan), the ZOMG (Zeppelin Of Mighty Gargantuaness), and the BAD (Big Airship of Doom). Tougher variants of most bloon types contain a number of specified weaker ones.<ref name="TD1 IGN">{{cite web|url=http://uk.ign.com/articles/2012/03/08/free-game-of-the-day-bloons-tower-defense|archive-url=https://web.archive.org/web/20140201065442/http://www.ign.com/articles/2012/03/08/free-game-of-the-day-bloons-tower-defense|archive-date=February 1, 2014|title=Free Game of the Day: Bloons Tower Defense|date=March 7, 2012|access-date=January 1, 2014|first=Justin|last=Davis|work=[[IGN]]}}</ref> In later versions of the game, regular bloons possess sometimes special characteristics such as camo (which most towers cannot detect), regrowth (the ability for the bloons to slowly grow back to their original size), and fortified (which doubles the health of certain bloons), that resist certain tower types.<ref>{{cite web|last=Bedford|first=John|title=App Of The Day: Bloons TD 5|url=http://www.gametrailers.com/mobile-apps/40183/app-of-the-day-bloons-td-5|archive-url=https://web.archive.org/web/20140102194559/http://www.gametrailers.com/mobile-apps/40183/app-of-the-day-bloons-td-5|archive-date=January 2, 2014|work=Gametrailers.com|access-date=January 1, 2014|date=November 26, 2012}}</ref> With each level, the intensity of bloon waves proportionately increases.<ref name="ASTD">{{cite web|url=http://www.appspy.com/review/3845/bloons-td|archive-url=https://web.archive.org/web/20131109093343/http://www.appspy.com/review/3845/bloons-td|archive-date=November 9, 2013|title=Bloons TD Review|date=October 4, 2009|access-date=January 1, 2014|first=Damian|last=Chiappara|work=App Spy}}</ref>

'''Towers'''

Towers are the main defensive utility in the ''Bloons TD'' series. Each tower has its own unique purpose, power, and use, with some being powerful against specific bloons but unable to target others effectively.<ref name="btd5rev">{{cite web|last=Aylott|first=Chris|title=Bloons TD 5 Review|url=http://www.slidetoplay.com/review/bloons-td-5-review/|publisher=SlidetoPlay.com|access-date=January 1, 2014|url-status=dead|archive-url=https://web.archive.org/web/20140217222022/http://www.slidetoplay.com/review/bloons-td-5-review/|archive-date=February 17, 2014}}</ref> Every tower can be upgraded to increase power and other capabilities by spending the in-game currency, known simply as 'money', which is earned by popping bloons and at the end of each round.<ref name="btd5rev" /> In ''Bloons TD 4'' onwards, certain towers such as banana farms can be placed to produce additional money during a round (end of the round in ''Bloons TD 4'').<ref name="GZ">{{cite web|last=Johnson|first=Leif|title=Bloons TD 5 Review|url=https://www.gamezebo.com/reviews/bloons-td-5-review/|archive-url=https://web.archive.org/web/20140102192435/http://www.gamezebo.com/games/bloons-td-5/review|archive-date=January 2, 2014|publisher=Gamezebo.com|access-date=January 1, 2014}}</ref>

In later games, there are multiple difficulty levels; for instance, in ''BTD5'', there are four difficulty levels and in ''Bloons Monkey City'' there are six. The higher the difficulty the player plays on, the fewer lives they have and the more each tower and upgrade cost. There are also different types of maps rated by difficulty; in general, there are more types of maps in newer games.<ref name=":0">{{cite web|url=http://www.technologytell.com/gaming/105565/android-amusements-bloons-td-5/|archive-url=https://web.archive.org/web/20140104070010/http://www.technologytell.com/gaming/105565/android-amusements-bloons-td-5/|archive-date=January 4, 2014|title=Android Amusements: Bloons TD 5|date=January 8, 2013|access-date=January 3, 2014|first=Jenni|last=Lada|work=Technology Tell}}</ref>
