Bloons TD 4 Expansion (also written as as Bloons Tower Defense 4 Expansion, Bloons TD4 Expansion, Bloons TD4 - Expansion, and BTD4 Expansion) is an expansion pack for the Flash version of Bloons TD 4. It was developed and released by Ninja Kiwi due to the demand for more Bloons TD games while Bloons TD 5 was still in development. It has the same gameplay as BTD4, but replaces the selection of tracks and adds Deflation mode and specialties. The Ninja Kiwi website and Ninja Kiwi Archive releases support the web account system and share the same save data, allowing progress, achievements, high scores, and in-app purchases in one game to carry over to the other. Unlike BTD4, this game was never released on Kongregate.

Differences from Bloons TD 4

• The title screen adds the Monkey Temple to the background and uses the Mortar Tower animation from older versions of BTD4's title screen instead of the Dartling Gun and Spike Factory.
• This game adds Deflation mode and specialties, but removes challenges.
  • Because of this, the Lickity Split and MOAB Madness achievements cannot be obtained in this game.
• The hint for round 1 was replaced and hints for the Monkey Temple Easter egg were added to the end of rounds 11, 60, and 73.

Round	Bloons TD 4	Bloons TD 4 Expansion
1	I really should make level 1 harder. Has anyone ever leaked a bloon on level 1?	Same old level 1 as always...free money really.
11	—	The 'Advanced' track in this expansion has a special secret.
60	—	Great sacrifice is required to unlock the secrets of the Temple.
73	—	The Temple awaits... can you discover how to unlock its secrets?

Tracks

This game includes all of the premium tracks from BTD4, but replaces the free tracks with four new tracks (referred to as "Expansion Tracks").

• 
  The Beach (Beginner)
• 
  Sewer (Intermediate)
• 
  Monkey Temple (Advanced)
• 
  Triangle (Expert)

Errors

Main article: List of errors in BTD4 (Flash)

This game shares most of the same errors with the current version of BTD4, but has its own errors.

• When hovering over the Dartling Gun or Spike Factory, the tooltip displays the Dart Monkey's sprite instead of their own sprites.
• It is possible to load a save created in BTD4 Expansion in BTD4. Doing this on any of the BTD4 Expansion-exclusive tracks causes BTD4 to load the save on Firecracker, allowing towers to be placed on the track or water. It is not possible to load BTD4 saves in BTD4 Expansion.

Version differences

The Ninja Kiwi and MochiGames releases launched as version "1.17 exp". They were later updated to version "1.18 exp" to add the Dartling Gun and Spike Factory after they were added to BTD4. Additionally, although the version number wasn't changed, both releases were updated to add Ninja Kiwi account support in 2014. The Newgrounds release still uses version "1.17 exp", so it lacks all of these additions. The Newgrounds release currently uses Ruffle to run the game on browsers that no longer support the Adobe Flash Player.
