Not to be confused with Bloons, the first ever Bloons franchise game (not a tower defense game.)
Stop any bloons from escaping the maze by building and upgrading bloons popping towers. Towers can throw darts, tacks, bombs, and ice. Can you make it through all 50 levels?
~ Official Description

Bloons Tower Defense (or Bloons Tower Defense 1) is the first game in the Bloons Tower Defense series. It is a tower defense game where monkeys and their towers try to stop enemy balloons (called Bloons) from getting through the track by popping them. There is only one track and one difficulty in the game, and the strongest bloons are the White Bloon and Black Bloon, which each contain two Yellow Bloons. (In later games, they contain two Pink Bloons.) Unlike other games in the series, the Bloons are very off-centered.

Bloon Types[]

In Bloons Tower Defense, the enemies are the bloons, like the original Bloons game. In the game, there are 6 different kind of enemy Bloons, some with their own unique special abilities.

Red Bloon[]

A red bloon.

The Red Bloon is the first enemy encountered in the game. Red Bloons are the slowest and weakest Bloon in Bloons Tower Defense. They do not release a bloon when popped.
First encounter: Round 1
RBE: 1

Blue Bloon[]

A blue bloon.

The Blue Bloon is the second enemy encountered in the game. Blue Bloons are slightly bigger and faster than Red Bloons. They release a Red Bloon when popped.
First encounter: Round 3
RBE: 2

Green Bloon[]

A green bloon

The Green Bloon is the third enemy encountered. Green Bloons are faster and bigger than Blue Bloons. Popping Green Bloons may be difficult at earlier rounds, due to their relatively fast speed compared to Blue and Red Bloons. They release a Blue Bloon when popped.
First encounter: Round 6
RBE: 3

Yellow Bloon[]

A yellow bloon.

Yellow Bloons are the fourth type of Bloon encountered. Yellow Bloons are very difficult to fend off during the earlier rounds due to their fast speed. They are the fastest type of Bloon in Bloons TD 1. They release a Green Bloon when popped.
First encounter: Round 11
RBE: 4

Black Bloon[]

A black bloon.

Black Bloons are the fifth type of Bloon encountered. They are immune to explosions. They release two Yellow Bloons when popped.
First encounter: Round 27
RBE: 9

White Bloon[]

A white bloon.

White Bloons are the sixth and last type of Bloon encountered in Bloons Tower Defense. They are immune to freezing. They can be considered as the "twin" of the Black Bloon, with the only difference being their immunities. They release two Yellow Bloons when popped.
First encounter: Round 41
RBE: 9

Glitches[]

  • If you place two Tack Towers too close to each other, neither will shoot.
  • If you use Tab to select an upgrade and then hold Enter to buy, you can buy that upgrade regardless of whether or not you have enough money which means that you can use the tack tower to fire at hypersonic speeds with 4-6 upgrades to get a super tack tower that can beat the game by itself. Doing this will in fact make your money go negative, so make sure that if you want to have other towers to get them before doing this glitch.
    • It is possible to complete the game using one well-placed glitch-enhanced tack tower, with all 40 lives remaining and a surplus of 29,410 money. The tack tower's shoot speed would be "hypersonic" given a Tab over to the shoot speed and four taps of the space bar.
    • Note that you have to be on the ninja kiwi website to preform the "hypersonic tower glitch ".

Trivia[]

  • The Pre-Round Comments claim that the game is impossible to beat with only Tack Towers. Ironically, this has been done several times already.
  • The Pre-Round Comments also claim that the developers were unable to beat the game without cheats or hacking.
  • The RBE of the entire game is 30160, which is close to 2 Z.O.M.Gs (33312).
  • Due to the short nature of this game, It is only possible to buy 7 un-upgraded Super Monkeys or 4 upgraded Super Monkeys in the game at one time.
  • This is the only BTD game where the Dart Monkey is called the Dart Tower and the Tack Shooter is called the Tack Tower.
  • This is the only BTD game that has no difficulty levels.
  • There is only one track in this game, unlike later BTD games.
  • This is the only game besides BTD 4 & BTD 5 where you can beat it using only sharp objects, due to Lead Bloons being introduced in BTD 2. (BTD4 & 5 in particular because of the explosive darts premium upgrade that allows dart monkeys to pop frozen and lead bloons.)
  • It actually is possible to win with only Dart Towers in this game, despite being harder than it

    Round 4 Tip

    looks. BTD2 acknowledges this, and on passing Round 4, the game leaves the tip "In Bloons TD 1, you could pass with only dart towers. In TD 2, I promise you that is no longer possible..."
    • This is most likely only because of Lead Bloons.
    • It would also be possible to beat a track in BTD4 and BTD5 using Dart Monkeys as long you had Splodey Darts (for both) or Juggernaut (for the latter).
  • Although Bloons are weaker, due to the high price of towers, lack of variety and only having 40 lives, this game is often considered to be the hardest game in the series, not counting very high freeplay levels in BTD3 and later.
  • Technically, the Black Bloon is the strongest bloon in the game (not the White Bloon) because of its immunity to bombs and from the fact that the only projectile that thaws Frozen Bloons are bombs.
  • This game is not a sequel to any Bloons TD game, but rather is a "spin-off" of the original Bloons series when Tower Defense games were popular.
