Bloons Tower Defense (also referred to with the retronyms Bloons TD and BTD1) is an Adobe Flash game in the Bloons franchise developed by Ninja Kiwi released in 2007. It is a spin-off of Bloons and the first game in the Bloons TD series. It is the basis of Bloons Tower Defense 2, which shares many assets and mostly the same gameplay.

Gameplay of Bloons Tower Defense

Bloons Tower Defense is a tower defense game in which the player places towers on a map to defend against waves of Bloons that move along a path. There are five tower types: the Dart Tower, Tack Tower, Ice Tower, Bomb Tower, and Super Monkey. Each tower type has two upgrades, except the Super Monkey, which only has one. The player can purchase upgrades on a tower in any order. There are six Bloon types: the Red Bloon, Blue Bloon, Green Bloon, Yellow Bloon, Black Bloon, and White Bloon, in order from weakest to strongest. There are a total of 50 rounds.

The map

The map (or "maze", as some flavor text calls it) is a grassy field with a stone path. The path starts on the left, rounds 13 bends, and exits at the top. The user interface normally blocks the right side of the map, though the player can place towers there with glitches.

Rounds

#	Bloon groups	RBE / cash	Hint
1	Red ×12	12	That was too easy, press 'Start Round' to play the next round.
2	Red ×25	25	Still super easy, you didn't miss any did you?
3	Red ×12 Blue ×2 Red ×12 Blue ×3	34	Blue bloons move faster and have red bloons inside them.
4	Red ×5 Blue ×12 Red ×5 Blue ×12	58	Remember to spend your money.
5	Red ×15 Blue ×10 Red ×15 Blue ×15	80	Green bloons move even faster and have blue bloons inside them!

10	Green ×35	105	Yellow bloons are - you guessed it, even bigger and even faster and have greens inside them.
11	Yellow ×15	60	Tower upgrades are usually a better option than just adding more towers.
12	Blue ×25 Green ×25 Yellow ×3	137	Tower defense is about what towers you use and where you put them.

14	Yellow ×28	112	You lose one life for every bloon that escapes. So a blue bloon costs you two lives, a green three lives etc.
15	Green ×30 Blue ×30 Green ×30	240	I've tried and you can't pass the game using only tack towers. You can slow the game down a lot though.
16	Blue ×20 Green ×30 Blue ×30 Green ×20 Blue ×20 Green ×25	365	Relax a bit, there are no yellow bloons in the next level.
17	Blue ×70 Green ×45 Blue ×70	415	Have you played Bloons?

25	Yellow ×25 Green ×30 Yellow ×28 Green ×40	422	Tack towers are really useful for thinning out the crowds - get the speed upgrade for extra effectiveness.
26	Yellow ×85	340	Black bloons are nasty - they are small but contain 2 yellows inside them. Oh did I mention they are IMMUNE TO BOMBS?!
27	Black ×20	180	When you sell a tower, you get 80% of what you paid for it, including all the upgrade money you spent.
28	Yellow ×55 Green ×45	355	Lots and lots of yellows - more than a hundred even, followed by a bunch of black bloons.
29	Yellow ×100 Yellow ×25 Black ×19	671	Next is a cash round - pop hundreds and hundreds of greens to top up your money. If you leak any I'll wince.
30	Green ×250	750	Monkeys aren't so good at shooting at things moving to their left. Something about being right handed I guess.
31	Black ×27 Green ×55 Blue ×10	428	The good thing about black bloons is that they move slower than yellows.
32	Yellow ×20 Green ×25 Black ×23	362	A - lot of yellows.

34	Black ×25 Green ×35 Yellow ×35	470	You will probably need to use every tower type to finish the game.
35	Yellow ×25 Green ×85 Yellow ×85	695	You can improve frame rate a bit by having no towers selected during the round.
36	Black ×17 Yellow ×115 Black ×18	775	Just black bloons coming up. Lots of 'em
37	Black ×59	531	Just around the corner there are a throng of yellow bloons waiting to have a go...
38	Yellow ×220	880	Just for fun, there are some of each colour bloon in the next level. Enjoy popping those easy reds for a change.
39	Red ×50 Blue ×50 Green ×50 Yellow ×50 Black ×40	860	80 blacks bloons. Enjoy.[sic]
40	Black ×80	720	Its important to not lose early lives, because the levels are only getting harder.

Despite the claims on round 15, the game is difficult to beat with only a Tack Tower on non-Newgrounds versions.

Strategy

• Place towers inside corners and turns on the track so their range covers as much of the track as possible.
• Selling should be avoided as much as possible, since income is very limited.
• In general, Dart Towers and Tack Towers are the only towers worth using due to their low cost and the lack of any Bloon types that resist them.
  • The Dart tower is cheap compared to its affects and cost. The Piercing Darts upgrade lets one Dart Tower pop 2 Bloons which is cheaper than another Dart tower. Long Range Darts are a poor choice since more towers will increase both damage and area coverage.
  • The Tack Tower is incredibly powerful at corners. You want to point as many tacks into the track as possible (highest on The Maze is 7). Early game the fixed projectile paths can leak Bloons but the more dense clusters can be cut through quickly due to its high damage. Place these as early in the track as possible to pop clusters before they break apart. New Tack Towers are more cost-effective than buying Faster Shooting as long as there are still ideal spots. Extra Range Tacks can be useful after your defense is stabilized to make hitting Bloons more consistent and reaching the opposite end of corners when several are packed into a small spot.
  • The Ice Tower is expensive, deals no damage, does nothing to White Bloons, and doesn't really help Dart Towers and Tack Towers since the freeze effect also makes Bloons immune to them. Both upgrades are bad since you should not be using this tower in the first place.
  • The Bomb Tower is expensive, has poor damage output due to its low attack speed, and does nothing to Black Bloons. If placed near the middle of the track, one or two can put in good damage. Bigger Bombs is a fine upgrade if you can afford it but is too expensive most of the time. Extra Range Bombs is pointless since the Bomb Tower already has a sizeable range and taking the upgrade increases the chance of missing bombs completely near the edge due to slow projectile speed.
  • The Super Monkey isn't worth saving up for. 9 Dart Towers and 8 Piercing Darts upgrades can be bought for about same cost and has roughly the same damage output. The Epic Range upgrade lets it hit most of the map from the middle but suffers from missing darts the further away the Bloons are from it, this can result in it getting distracted by a Bloon across the map and failing to hit it while the rest break through your defenses.

Bugs and glitches

Upgrade stacking glitch

Main article: Upgrade stacking glitch

By pressing Tab until an upgrade button is highlighted then pressing Enter to purchase it, the player can purchase that upgrade multiple times on one tower. There's no limit to the number of times the upgrade can be bought, and it doesn't stop if the player can't afford it, which puts their money into the negatives. One application of this glitch is to use the Tack Tower's Faster Shooting upgrade to increase its attack speed to the cap of 40 shots per second; this is often called the "hypersonic Tack Tower glitch".

Unused content

Spikey Ball Tower

The Spikey Ball Tower is an unused type of tower. It shoots volleys of spiked balls in four directions, similar to the Tack Tower. It has no description or upgrades. The spiked balls use the same graphic as the Spikey Ball Bloon from Bloons.

Descriptions

Ninja Kiwi

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?

MochiGames

Try to pop every bloon before it escapes the maze. Place different kinds of towers around the maze to pop them all.

Newgrounds

I love tower defense games, and Bloons was fun to make, so I thought we'd try a mix of the two ideas in one game. Have fun!

Instructions

Click on the tower type you want to build on the right side of the screen, then once its selected, place the tower in the maze. Press escape to deselect or cancel your current action. You can sell towers for extra money for 80% of what you paid for them. Larger coloured bloons have smaller bloons inside them, so watch out!
