“	So you think you've mastered the game? You've beaten heaps of tracks, gained a ton of gold medals, and even conquered tracks in reverse. You think you might just be unstoppable … Well think again as update 2.8 introduces Impoppable mode, an insane new difficulty taking the game to a whole new level of extreme! More expensive towers, faster and stronger Bloons, and did we mention you can't lose any lives? Challenge yourself with Impoppable, but don't say we didn't warn you.	”

Btd5imp1 — Welcome message on version 2.8

The Impoppable Difficulty is a difficulty released for Bloons Tower Defense 5 Mobile in update 2.8. Being the newest and most challenging difficulty, it is unlocked at Rank 35 and offers higher rewards upon completion.

In this difficulty, players begin with 1 life, with upgrades such as Healthy Bananas and Support Chinook providing no extra lives. Towers and upgrades are 20% more expensive than Medium Difficulty. Bloons in this difficulty are 25% faster than Medium, Ceramics have 50% more health, and MOAB-class bloons have double health. The final round (85) spawns five Z.O.M.G.s instead of one.

Tips

Due to its devastating rule of 1 life only, a Spike Factory or Bloonberry Bush is a must have. You should not be over-confident with your towers. If you're worried about fast bloons going through your defense (Ceramics are faster now), use Glue Gunners, Ice Towers, or the Sabotage Supply Lines ability (for MOAB-Class Bloons).
Road Spikes are fairly useful in catching the Bloons that get by your towers, but if you find yourself using them a lot, you should invest in a Spike Factory instead.
Round 85 Impoppable is arguably the hardest non-DC and non-freeplay round on the whole BTD series. You shouldn't always rely on 5 First Strike Capability, especially for tracks like Bloontonium Lab; unless you have a Portable Lake. Sabotage Supply Lines is useful for both slowing down the ZOMGs and their children. Technological Terror's ability might help finish off the BFBs. In Bloontonium Lab, even a Max Temple Of The Monkey God might have trouble with Round 85, so have some back up towers ready to go, or use its ability if you have the Tier 4 Super Monkey Lair activated.
Likewise, farms always help the ease of a difficulty, however, paying attention to the farms too much might mean game over, especially because you must focus on tapping the bananas. Spending a measly sum of 40 on a Monkey Farmer can direct your attention more towards the track in the early game, preventing loose bloons from getting through.
Super wide funnel can be useful as it can destroyM.O.A.B. class bloons easily, which have noticeably higher health than on other difficulties.

Trivia

Upon completing a track on Impoppable Difficulty, a medal will be earned along with an achievement called "Poppable".
- There is also an achievement called "Nigh Impoppable", which is achieved by getting the Impoppable medal on 25 or more different maps.
The Olympian achievement for tracks (earned by getting all medals for a track) doesn't include impoppable, meaning that getting reverse, bronze, sliver, and gold will get you the medal.
The Lives Injection can't be used because it gives extra lives. However, The Cash Injection can be used.
The Support Chinook upgrade drops health crates, but they do not add additional lives, either.
The medal looks somewhat like a black poker chip.
In this difficulty the level 85 Pre-Round Comment has changed. Comment: Next up is the final round, beat it and you'll gain the Impoppable medal. You won't though, this has been a waste of time and you won't survive what's coming. At least you had fun.
"Impoppable" is a portmanteau of "impossible" and "pop".
When a tower is under a village, it will cost the same as on Hard.
Because 3/X Sniper Monkeys only do 18 Damage, they will get rid of the ceramic layer on Hard but not on Impoppable, leaving Pinks behind.
