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 4 ExpansionEdit

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.

Bloons Monkey City and BMC MobileEdit

The difficulties for this game are Trivial, Easy, Medium, Hard, Very Hard, and Impoppable. Unlike the BTD games, the player cannot select a difficulty. Instead, each tile is assigned a difficulty. The difficulty decreases as the player progresses, for example, when the player starts Pink Bloon tiles may be Impoppable, but later, the player may see a trivial MOAB tile or a easy BFB tile.


  • It takes 42 seconds for a Red Bloon to go past the exit of Monkey Lane on Easy, 40 seconds on Medium and 38 seconds on Hard.

    • Yes. Green -> light green (Easy -> trivial)
  • What's happened to the My Tracks difficulties?

    • Also, the cash reward (with logistical boots) is $990. I am level 33 (now). I could probably beat such a tile on Flower, but the cash reward ...
