Impoppable is a game mode in Bloons TD 6. It is unlocked on a map-by-map basis by beating Alternate Bloons Rounds. Beating Impoppable unlocks the CHIMPS gamemode.

On Impoppable, players start with only 1 life and all means of gaining lives (including Mana Shield) are disabled. In addition, towers and upgrades cost 20% more than on Medium Difficulty (equal to roughly 11% more than Hard Difficulty). Standard games of Impoppable begin on Round 6 and end on Round 100, when the BAD appears. In special challenges that are not set on Hard, prices are raised by +11.1%.

It is worth a note that Rounds 81+ start to increase health and speed of MOAB-Class Bloons and all Ceramic Bloons are replaced with the Super Ceramic variant. More specifically, every Round past 80 increases MOAB health and all bloon speeds by 2% (e.g. ZOMGs on Round 85 have 4400 HP).

Strategy[]

Summary[]

The basic purpose of Impoppable Mode is to prepare the player for the challenge of CHIMPS Mode. The restriction of having only 1 life means that very careful play is required to survive. Especially on rounds 81+, where bloons get faster, Ceramics become Super Ceramics, and MOAB-Class Bloons get extra health. Prices are also higher while keeping the use Monkey Knowledge, income production, Powers, Continues, and selling.

Tips[]

  • Green Bloons spawn immediately at the start of Round 6; as such, any successful early-game defense must be able to handle these without relying too heavily on Pre-Game Prep.
  • While by no means necessary, farming can make affording more expensive upgrades easier.
  • Pre-Game Prep can be extremely helpful in the early rounds, allowing the player to save up for a more expensive early-game tower. Don't rely on them entirely, as some maps prevent the spikes from not getting consumed by closeby entering bloons, but do make good use of this Monkey Knowledge Point to your advantage.
  • Passive abilities that activate upon losing lives (those of Bomb Blitz and Elite Defender) are useless on this mode without Corvus's Soul Barrier, as losing a life results in a game over, unless Legend of the Night's passive black hole ability is active. Ezili's Sacrificial Totem ability is also disabled.
  • Due to Mana Shield and Healthy Bananas being disabled, Spike Factories are more viable because of this restriction. Spike Factories can substitute as a "Mana Shield", saving the player from small amounts of bloons that get past their defenses.
    • If the player uses Spike Factory, it's recommended to get Perma-Spike due to its ability to withstand a large amount of bloons.
    • Alternatively, the player can use upgrades like Downdraft or Druid of the Storm to blow back bloons if they reach too close to the exit.

Version history[]

In Version 16.0, Impoppable Difficulty was changed so that Mana Shield is disabled, and the maximum lives the player can have was fixed to 1 life by default. According to Ninja Kiwi, Mana Shield was never intended to be usable in Impoppable and was only usable due to miscommunications among developers.

16.0
  • NERF Mana Shield is now disabled in Impoppable Mode.
  • NERF By default, the maximum number of allowed lives in Impoppable is now always 1. Extra lives cannot be earned unless the maximum limit is raised either in the Challenge Editor or in developer-sanctioned events.
37.0
  • NERF [Bug] Impoppable cost multipliers now multiplies on top of the default difficulty multipliers, resulting in the base Impoppable mode now increasing the cost of towers and upgrades by 29.6% instead of 20%.
37.1
  • BUFF [Bug fix] Impoppable no longer scales on top of Hard difficulty.
    • Change Impoppable price modifier reduced from 20% → 11.1%
    • Change Impoppable cost multiplier stacks on top of the Easy and Medium difficulty.

Quotes[]

On Impoppable Monkeys cost much more than normal, you start at round 6, the Bloons move faster and you have 1 life. Beating round 100 in Impoppable awards you a platinum medal for that track.

Trivia[]

  • While Impoppable is not considered a difficulty in BTD6, it has an unused difficulty description, suggesting it may have originally been planned to be one.
    • The description refers to the medal as the "platinum medal", unlike in BTD5, where it was referred to as the "Impoppable medal", or Bloons Adventure Time TD, where it is known as the "diamond medal".
  • Unlike its BTD5 counterpart, Bloons in Impoppable move at the same speed as a normal Hard game, and Ceramic and MOAB Class Bloons don't have more health. However, they progressively get more health beyond round 80, with Ceramics becoming Super Ceramics and MOAB-class bloons gaining +2% health and speed per round.
    • Before the last round starts in BTD5 Impoppable counterpart, it had shown specific pre-round comment exclusive to Impoppable. However, in BTD6, there is no exclusive pre-round comment before Round 100 in Impoppable.
  • Winning Impoppable Difficulty in a normal game guarantees one free Insta-Monkey, just like beating Round 100 in all other games.
  • According to Ninja Kiwi's 15th October 2021 blog, the icon is a Sun Avatar captured in an eerie green glow of battle.
  • [Pre 37.0] Impoppable Difficulty could be set as a submode for the Easy and Medium difficulties on the Challenge Editor. If this mode is selected on these difficulties, the tower prices and upgrades will still be the same as an Impoppable game (20% higher cost than a Medium game), but the bloons will move at the speed set for the game mode. The only difference with an Easy or Medium Impoppable game versus a Hard Impoppable game with the default settings was slower bloon speed.
    • [Pre 37.1] In addition, towers and upgrades cost 20% more than its selected difficulty. This means by default, the base Impoppable gamemode on Hard difficulty will increase the price of things by 29.6% instead of the typical 20%, due to a bug.
    • Since 37.1. this is no longer a case and Impoppable modifies the prices of Easy and Medium but not Hard.
