Sulfur Springs (spelled Sulphur Springs in some update notes) is an Intermediate map in Bloons TD 6, introduced in version 41.0. It is a hot spring surrounded by a lava flow.

Layout

On Sulfur Springs, Bloons enter from the top, make 1.5 clockwise loops around the top small loop, then make 1.5 counter-clockwise loops around the large central loop, and finally make 1.5 clockwise loops around the bottom small loop before exiting. The central hot spring and the 2 streams, one on the left and one on the top-right, can fit water towers. The central hot spring is surrounded by land that can fit towers up to the size of Super Monkeys. There are 3 rocks at a lower elevation than most of the map, one in each small loop and one to the top-left of the central spring.

Strategy

By consensus, Sulfur Springs is the easiest Intermediate map in BTD6. The many loops Bloons take give towers multiple opportunities to attack them, the central spring and surrounding land are very optimal placements, and the track is one of the longest out of the Intermediate maps. Sulfur Springs can be beaten quite easily with the general guidelines below.

• Basic Deflation strategies
• Basic Apopalypse strategies
• Basic Half Cash strategies
• Basic Alternate Bloons Rounds strategies
• Basic Impoppable strategies
• Basic CHIMPS strategies

Sulfur Springs's layout allows certain towers listed below to shine.

Recommended towers and upgrades

Name	Portrait	Reasoning
Ultra-Juggernaut		If placed on one of the 3 lower-elevation rocks, the Juggernaut balls can bounce off the walls and rehit Bloons multiple times, making them much deadlier. It wipes out the mid-game with ease and does solid general late-game damage, especially to clumped MOABs and Super Ceramics. The presence of these walls is also why Apex Plasma Master stands out on this map.
Destroyer		Destroyers gain widespread coverage in the central hot spring, with the ability to attack on both sides frequently. Five of them breeze through the mid-game when given camo detection and a Stronger Stimulant, which, when upgraded to Perma-Brew after an easily doable saveup, grants the Destroyers 8x damage and wipes the floor with the late-game. Use Admiral Brickell to maximize the power of the Destroyers.

Easter egg

Interacting with the geysers triggers animations and sound effects. Interacting with them in a specific order, plays a special sound cue on each interaction, and interacting with the last one causes them all to erupt. This can only be activated once per game.
