List of rounds in BTD6

This is a list of all standard rounds in Bloons TD 6 and the default round-based Bloon modifiers. Some modes, quests, and events have different rounds and/or modifiers.

Standard rounds

Note:

• The RBE amounts do not factor in the reduced RBE of the round 40 MOAB when playing on Easy, or the RBE reduction from Big Bloon Sabotage, or any mode/editor-related RBE modifiers.
• The XP amounts do not factor in the reductions to tower and player XP in freeplay and after round 100 (e.g. the values are only accurate for Hero XP after the last required round of the current difficulty).

Game hints

End of round	Text

7	Keep playing Bloons TD 6 regularly and check for new updates - maps, heroes, challenges, and other awesomeness.
12	The more you use a certain Monkey, the more upgrades you will unlock for using it.
26	See those Zebra striped Bloons? They combine the meanness of White Bloons and Black Bloons, and contain one of each just for fun.
32	You saw one Camo Bloon back on round 24. Hope you're ready for more!
38	End of next round has 2 Regrow Rainbow Bloons. If handled poorly, 2 could turn into many more...
39	First MOAB-Class Bloon next round. Don't say you weren't warned!
41	Coming up: Regrow Rainbow Bloons and Camo Rainbow Bloons. You all sorted for this?
45	Fortified Ceramic Bloons coming up next.
50	Lots of Camo Ceramic Bloons could wreck your day. Just sayin'.
54	BTD6 is awesome. Life is awesome too. Don't forget to have a break sometimes and do something else. Then play more BTD6!
58	Can you pop Lead? Can you pop Camo? How about... Camo Lead?
59	Final round for Medium difficulty coming next. Congratulations! If you can pop the BFB Bloon that is...
62	If you played BTD5 you'll remember what Round 63 was like. If you are new to this game, let's just say: many tightly packed Ceramic Bloons.
73	Next round: Camo Regrow Fortified Ceramic Bloons. Phew! What a mouthful.
77	What happens when you cram 75 Ceramic Bloons into a tiny space? You're about to find out!
79	Final round for Hard difficulty next. Throw everything you've got at the ZOMG Bloon. It's big and slow, but very very tough.
89	What's a DDT Bloon you ask? Like a MOAB crossed with a Pink, Camo and Lead Bloon. In all the bad ways.
100	Congratulations on beating round 100! Enjoy your reward!

Modifiers

Bloon speed

The speed of Bloons increases by 2% per round starting on round 81 but with sudden jumps on some rounds.

Rounds	Formula	Note
81-100	$(1+(round-80)\times 0.02)$
101-150	$(1.18+(round-80)\times 0.02)$	additional 18% speed on round 101

252+	$(2.56+(round-80)\times 0.02)$	additional 48% speed on round 252

MOAB health

The health of MOAB-Class Bloons increases per round starting on round 81. This does not affect their life lost if leaked.

Rounds	Modifier (per round)	Formula
81-100	+2%	$(1+(round-80)\times 0.02)$
101-124	+5%	$(1.4+(round-100)\times 0.05)$
125-150	+15%	$(2.6+(round-124)\times 0.15)$
151-250	+35%	$(6.5+(round-150)\times 0.35)$
251-300	+100%	$(41.5+(round-250)\times 1.00)$
301-400	+150%	$(91.5+(round-300)\times 1.50)$
401-500	+250%	$(241.5+(round-400)\times 2.50)$
500+	+500%	$(491.5+(round-500)\times 5.00)$

Cash per pop

Bloons give less cash per pop starting on round 51.

Rounds	Modifier
51-60	50%
61-85	20%
86-100	10%
101-120	5%
121+	2%

Spawning changes and Super Ceramic Bloons

Starting on round 81, all non-MOAB-Class Bloons will only spawn one child Bloon when popped instead of two in order to reduce lag. (Zebra Bloons will always spawn Black Bloons.) To compensate, Ceramic Bloons are replaced with Super Ceramic Bloons, which have 60 health instead of 10 (120 instead of 20 when fortified) and give $87 when the Ceramic layer is popped instead of $1 (affected by cash per pop scaling). Leaking a Super Ceramic Bloon will cause a 65 lives lost (75 if fortified). Other Bloons do not gain more health or give extra cash, despite also spawning less Bloons.

Status resistances

The duration of certain statuses is reduced starting on round 150.

Rounds	Duration reduction
150-199	10%
200-249	20%
250-299	30%
300-349	40%
350+	50%
