This article is about the three (four on mobile) game modes. It is not to be confused with Track Difficulty.

Difficulty is what determines how hard or challenging a Bloons Tower Defense game is. Difficulties were introduced in BTD2 and have been in every BTD game since. There are 4 difficulties: Easy, Medium, Hard, and Impoppable.

Bloons Tower Defense 1Edit

  • No visible difficulty variations - 1 track, 1 difficulty. Finish on round 50.

Bloons Tower Defense 2Edit

  • 1 track per difficulty. Finish on round 50.

Bloons Tower Defense 3Edit

  • Pick a track, then pick a difficulty

Bloons Tower Defense 4Edit

  • Pick a track, then pick a difficulty
  • BTD4 is where they added Track Difficulty, categorized by how hard the actual track is. This is shown in the select a track page.
  • Easy has towers and upgrades cost at 85% of Medium prices, 200 lives and 50 rounds.
  • Medium Difficulty has towers and upgrades cost the normal amount, 150 lives and 60 rounds.
  • Hard Difficulty has towers and upgrades cost at 108% of Medium's prices, 100 lives and 75 rounds.
  • Each difficulty also applies to Bloons Tower Defense 4 Expansion.

Bloons Tower Defense 5Edit

  • Same as BTD4, but with slight speed alterations, and Hard Difficulty has ten more rounds to pass than BTD4, and Medium Difficulty has 5 more rounds.
  • Each difficulty (Easy, Medium, Hard) is the same thing as Difficulties for BTD4, except that bloons move slightly faster the harder the difficulty.

Bloons Tower Defense 5 MobileEdit

  • Easy, Medium and Hard Difficulties are the same as BTD5.
    • Impoppable Difficulty is introduced, where you have one life and the towers as well as their upgrades cost 20% more than medium or 10% more than on Hard.
