BTD4 New Challenges

Challenges are game modes in Bloons TD 4. Each challenge involves completing a track with added stipulations, such as having a limited selection of towers or having only one life.

In the Flash version, there are only four challenges. In the Mobile version, there are many more challenges, with a greater variety of stipulations.

Challenges do not exist in Bloons TD 4 Expansion.

List of challenges[]

Flash version[]

Ocean Road[]

Oceanroad challenge
  • Difficulty: Medium
  • Objective: Beat this track on Medium using only Dart Monkeys and Super Monkeys.
  • Solution: You can upgrade them to Spike-O-Pults and Sun Gods, respectively. It is quite difficult to destroy the Lead Bloons, unless you have the Exploding Darts Premium Upgrade or the Double Cash Mode enabled, as Plasma Vision is needed. Otherwise, you will have to rely on timing Pineapples at the right time.

Ant Hill[]

Anthill challenge
  • Difficulty: Hard
  • Objective: Beat this track with only one life.
  • Solution: TBA

Lollipop[]

Lollipop challenge
  • Difficulty: Easy
  • Objective: Beat this track with only Dartling Guns and Spike Factories.

Pool Table[]

Pooltable challenge
  • Difficulty: Medium

Trivia[]

  • While the challenges menu in the Flash version states that more challenges are coming soon, no challenges have been introduced since 2011.
  • Road items (Road Spikes, Monkey Glue, and Pineapples) are available on any challenge, including those that have limited towers.
  • These are similar to the Daily Challenges and Special Missions in BTD5.
  • In the Lollipop challenge, it is still possible to place Dart Monkeys using its hotkey (D).
  • In the Self Destruct challenge, if there are no towers on the map on rounds when one would normally be destroyed, the game crashes.
  • The BTD4 Flash Ant Hill challenge appears to be a precursor to Impoppable Mode in BTD5 Mobile.
