The best towers in Bloons TD 6 are not always the most expensive ones. A strong Monkey is one that solves the problem in front of you: it may clear packed Bloons, damage MOAB-class targets, reveal Camo, strengthen nearby towers, or protect the exit when everything else fails. Learn the reliable choices below and you will be able to build better defenses on almost any map.
BTD6 has a large tower roster, three upgrade paths per tower, Heroes, map-specific placement limits, and modes with very different rules. That is why a simple universal tier list can be misleading. A Banana Farm can be essential in a Boss run but has no place in CHIMPS. A powerful water tower cannot be placed on a dry map. A tower built for huge MOAB damage may struggle against a dense group of ordinary Bloons.
The better question is: which strong tower fits the current map, rules, and threat? Once you answer that, your choices become far clearer.
The most valuable towers tend to have one or more of these qualities:
They are efficient for their price at the point you buy them.
They solve an important Bloon property such as Camo, Lead, or MOAB-class health.
They scale well with buffs, debuffs, support, or additional copies.
They are flexible enough to help on more than one map type.
They give the player control through targeting, abilities, slowing, stuns, or global range.
No tower needs to do all of these things. The real strength of a defense comes from combining a few clear roles instead of asking one Monkey to solve every problem alone.
Ninja Kiwi regularly adjusts towers and adds new choices, so exact rankings change. A popular strategy may become less efficient after an update, while a tower you rarely used can become excellent. Build your understanding around roles and interactions. That knowledge lasts much longer than a copied “top five towers” list.
These towers are worth learning because their roles stay useful across a wide range of standard games. They are not compulsory in every build, but each teaches an important part of BTD6 strategy.
The Alchemist is powerful because it can improve another tower instead of only adding its own damage. Its buffing path can increase the attack speed, damage, and pierce of a nearby main attacker. That makes an Alchemist especially efficient when it is positioned to support a single high-value damage tower or a small, carefully chosen group.
The common mistake is placing an Alchemist where its buffs spread across too many low-value towers. First decide which Monkey is carrying the defense, then put the Alchemist close enough to improve that Monkey consistently. The Alchemist also has paths that help with Lead Bloons and cash generation, making it a flexible support option rather than only a damage buff.
The Monkey Village is a force multiplier. Its upgrades can provide range, Camo detection, discounts, stronger damage interactions, and major ability-based buffs to towers within its radius. That makes it especially useful when several important towers can share one location.
The Village is not an automatic early purchase. It becomes good when the value of the support it gives is greater than spending the same cash directly on damage. A Radar Scanner can solve a Camo problem for a compact defense. A Monkey Intelligence Bureau can remove many damaging restrictions for a key group. Call to Arms and its later upgrade can turn a planned damage window into a huge burst of power.
On maps with useful water placement, Monkey Subs offer several practical roles. They can provide early damage, Camo coverage through the right upgrade path, strong MOAB-class damage, and support for other Subs. Their range and interactions reward smart water placement, especially where several Subs can cover the same section of track.
Do not force a Sub strategy on every water map. The quality of the water spot and its line of attack matter. When water is positioned well, though, the Sub is one of the most efficient towers to understand from early games through more demanding content.
Ninjas naturally interact with Camo Bloons, which removes one early defensive concern. Their fast attacks, seeking projectiles, and later support options make them adaptable on many maps. A Ninja can serve as an early core, a source of slowing and disruption, or a fast attacker that benefits strongly from nearby buffs.
The Ninja is a particularly good tower to learn because it shows how an attacker’s role can change by path. Do not assume every Ninja upgrade is simply “more damage.” Some paths focus on direct attacks, some on abilities and disruption, and others on stealth-based utility.
Glue Gunners do not look like a headline damage tower, but slowing Bloons gives every attacker more time to work. This is extremely valuable when a tough MOAB-class Bloon is moving through a narrow defense or when a dense group is reaching the exit. The Glue Gunner also has paths that improve grouped-Bloon damage and create powerful debuff windows.
Control is often cheaper than buying another large attacker. If your defense nearly succeeds but Bloons move through it too quickly, a Glue Gunner can be a better answer than adding more raw damage.
The Ice Monkey offers several forms of utility: freezing, slowing, stronger damage against affected Bloons through the right path, and powerful late-game support. On a good placement point, it can create a long period where other towers safely deal damage.
Ice is not universal. Some Bloon properties and map layouts reduce its value, and a poorly placed Ice Monkey can cover very little track. Use it where the track passes close by or where its support can affect the targets your main damage tower is already hitting.
Snipers are easy to place because they can attack from almost anywhere with line of sight. They give you useful targeting choices and can be built toward fast fire, stronger MOAB-class damage, grouped-Bloon support, cash generation, or control. This makes them reliable on maps where a normal tower cannot see enough of the path.
Their global reach does not remove the need for good targeting. A Sniper set incorrectly may shoot the wrong target while Bloons escape elsewhere. Change targeting when a tough target becomes the priority, and use a cleanup layer close to the exit if the map demands it.
Spike Factories are valuable because they can store damage on the track before Bloons arrive. A well-placed Spike Factory near the exit catches leaks, protects against sudden pressure, and gives your main defense a second chance. Its different paths also allow for grouped damage, ability-focused bursts, and extremely durable end-of-track protection.
This is why the Spike Factory is strong on many difficult maps: it does not need perfect line of sight, and it does not compete for the same ideal attacking position as your front-line towers.
Standard games reward a balanced build that is easy to place, solves common Bloon properties, and does not require a complicated economy plan. The goal is consistent map completion rather than maximum theoretical damage.
The Tack Shooter is excellent when placed beside tight curves, loops, or spots where Bloons pass very close. It turns good geometry into a large amount of damage. The Boomerang Monkey performs well when its attacks can travel through a line of Bloons or return through a busy section of path.
Both towers teach an important lesson: placement can be more important than raw cost. Before buying another upgrade, move your attention to where the track bends, overlaps, or remains in range for longer.
The Wizard Monkey is a comfortable standard-game choice because its paths can contribute different types of damage and utility. Depending on the path, it can handle Camo, clear groups, create strong burst moments with abilities, or become a major late-game attacker.
Use the Wizard as part of a composition, not as an excuse to skip the fundamentals. It may still need help against specific properties or tough single targets. Pair it with support and targeted MOAB damage when the map reaches harder rounds.
In normal games and Boss content, a Banana Farm can turn a stable early defense into a much stronger late-game one. More income means you can afford the towers, upgrades, and support your strategy needs before the biggest threats arrive.
Farms are not free power. Every Farm delays immediate defense, so only invest when the current setup is stable. On a difficult map, a small defensive purchase that prevents a loss is more valuable than an early Farm that leaves the path exposed.
CHIMPS changes the way you evaluate every Monkey. The mode removes Continues, extra lives, income beyond normal popping, Monkey Knowledge, Powers, and selling. You cannot rely on Farms, mistake recovery, or permanent account bonuses. Efficient damage, careful placement, and a clear plan matter far more.
Without income-generating strategies, every purchase must help the eventual defense. Look for a strong main damage tower that can carry a large part of the game, then add inexpensive support that fixes its weaknesses. Buffs, slowing, Camo support, and debuffs often offer more value than buying several unrelated attackers.
Ninja and Alchemist combinations, well-positioned Tacks, Subs on suitable water, and compact Village-supported cores are examples of concepts that can work. The exact build still depends on the map and your unlocked upgrades.
CHIMPS rewards players who make every second of tower fire count. MOAB-focused slows, freezes, stuns, and disruption can allow a smaller damage setup to beat a threat that would otherwise require a much larger investment. Glue Gunners, Ice Monkeys, Snipers, Ninjas, and certain Heroes can all contribute through control as well as damage.
Do not depend on control alone. Tougher Bloons still need enough damage to be popped before they reach the exit. Combine control with a reliable single-target attacker and a fallback such as a Spike Factory when the map allows it.
Many CHIMPS losses happen because a build is strong against ordinary Bloons but cannot correctly damage a later Camo or DDT threat. Do not wait until that point to check your setup. Ensure your core damage has the detection and damage types it will need, or reserve space and cash for appropriate support.
Bosses are massive MOAB-class targets with mechanics that vary by boss. A strategy that destroys one Boss quickly may be poor against another. Instead of memorizing one list, build around three principles: enough income, enough single-target damage, and the right support for the current boss.
Boss runs often require expensive towers much earlier than ordinary games. Once your starting defense is stable, build an economy that matches the map rules and your plan. Banana Farms are common because they help pay for the powerful anti-Boss damage and support required later.
Do not copy a farming plan blindly. If the Boss has a mechanic that disrupts farms, buffs nearby Bloons, drains resources, or forces fast defense, adjust the timing. The goal is to arrive at each Boss stage with a stable defense and enough cash for the next answer.
For Boss damage, direct single-target attackers are usually more important than towers built only for ordinary Bloon groups. Strong Dartling Gunner, Monkey Ace, Sniper, Sub, and Super Monkey paths can all be relevant depending on the map and budget. Later on, Paragons may become part of a high-tier plan.
Support matters just as much. A debuff that makes the Boss take more damage, a burst-speed buff, or a Village that allows a key tower to ignore an immunity can greatly improve the value of the main attacker. Stack only buffs that genuinely affect the towers you are using; an expensive support tower doing nothing useful is wasted cash.
Bosses are not simply larger MOABs. Some speed up nearby Bloons, some interfere with tower placement or abilities, some force special detection requirements, and some create extra threats as their health changes. Read the Boss information before settling on your final build.
That preparation prevents one of the most expensive BTD6 mistakes: buying a powerful tower that is poorly matched to the Boss’s mechanics.
Freeplay is where raw scaling becomes important. Bloons gain far more health, and eventual BADs require enormous damage. A normal map-completion defense will not automatically scale into a very long run.
Paragons, powerful Super Monkey upgrades, major aircraft, and other expensive Tier 5 towers are natural Freeplay goals because they can contribute the damage that late-game health totals demand. The right choice depends on the map, the available placement space, and how much farming you completed before committing to Freeplay.
Do not rush toward one expensive tower while ignoring the rest of the defense. Late-game damage becomes better when supported by buffs, debuffs, extra range, and enough coverage to deal with non-BAD threats as well.
Even when raw damage is the main goal, support has a place in Freeplay. Slowing and stalling regular MOAB-class Bloons gives your strongest attackers longer to fire. A Spike Factory near the exit provides insurance against leaks. Support towers also help keep Ceramics and other non-Boss threats from overwhelming a defense focused on BADs.
Remember that not every form of control affects every target equally. Test the interaction before spending heavily, especially when moving from normal Freeplay into Boss or Elite content.
Co-op becomes much easier when players cover separate jobs. Four players buying the same expensive damage tower can be less effective than one player bringing support, one handling MOAB damage, one protecting against groups, and one developing the economy.
Talk before the map begins. Decide who will cover early damage, Camo, Lead, income, and late-game single-target damage. A player with a well-placed Village or other support can improve several teammates’ towers at once. A player with global-range towers can protect difficult portions of the map while another builds around a strong local placement.
Support becomes weaker when everyone buys the same effect without a reason. If one player already provides detection and a damage-enabling Village to the core, another player may be better served investing in direct damage or control. Co-op rewards communication because nearby tower synergies can be shared.
When you are not sure what to build, use a simple decision process instead of searching for a single “best Monkey.”
Ask these questions before buying an upgrade:
Is there water, a tight bend, a loop, or a long sightline that favors a particular tower?
Does the current defense handle Camo and Lead?
Do you need grouped-Bloon control or focused MOAB damage next?
Is the map difficult because of short track length, blocked line of sight, or awkward placement?
Are the mode rules allowing income, selling, Monkey Knowledge, and Powers?
The answers narrow the tower pool quickly. This is far more reliable than selecting the same Tier 5 tower on every map.
Choose the tower that will do most of the damage, then ask what would improve it. It may need an Alchemist buff, Camo support from a Village, a Glue Gunner to hold targets in range, or a Spike Factory to catch leaks. Support should make the main plan stronger, not exist because it appears high on a tier list.
Many builds fail because every strong tower is placed near the entrance. A small cleanup tower, a Spike Factory, or a carefully targeted global-range unit near the exit can turn a close loss into a safe win. Treat the final portion of the path as a deliberate defensive layer, especially on short or difficult tracks.
Every expensive tower has a weakness. It may need Camo detection, have poor group damage, depend on a good placement spot, or require support to perform at its best. Build around the weakness instead of assuming cost solves it.
A strategy with Farms, selling, Monkey Knowledge, Insta Monkeys, or Powers may work perfectly in a normal game and be impossible in CHIMPS. Always check the ruleset before using a guide or planning an economy.
Buying too much low-tier damage can delay your important upgrades and support. Use enough early defense to remain safe, then convert your cash into a clear core strategy. Efficient placement and targeting often let you buy less at the start.
Tier lists are useful for discovering towers, but they do not know your map, rule set, available water, or current weakness. Use them as inspiration, then make the actual decision based on the game in front of you.
What is the strongest tower in Bloons TD 6?
There is no single strongest tower in every situation. The Monkey Village and Alchemist are among the most valuable support choices, while the best damage tower depends on the map, mode, budget, and the Bloons you need to defeat.
What are the best towers for beginners?
Learn Dart Monkey, Tack Shooter, Ninja Monkey, Alchemist, Sniper Monkey, Monkey Sub, Monkey Village, and Spike Factory first. Together, they teach efficient placement, Camo coverage, buffs, targeting, water strategies, and cleanup.
Are Banana Farms good in every mode?
No. Farms are excellent when the mode allows extra income and you can defend safely while investing in them. CHIMPS disables income beyond popping Bloons, so Farms do not belong in that mode.
Which towers are best against MOAB-class Bloons?
Focused single-target paths from towers such as Sniper Monkey, Monkey Sub, Dartling Gunner, Monkey Ace, and Super Monkey can be strong choices. Pair them with slowing, debuffs, and useful buffs rather than relying on one attacker alone.
Do I need a Monkey Village in every game?
No. A Village is strongest when several important towers fit in its range or when its detection, damage-enabling effects, discounts, or abilities solve a real weakness. It is unnecessary if your core already covers those needs efficiently.
Why does a copied build fail on another map?
Maps change tower value through track length, bends, obstacles, line of sight, water placement, and available building space. Copy the build’s purpose—such as group control, Camo support, and MOAB damage—then adapt the towers and placement to the new map.

Boss Bloons ask a different question from a normal Bloons TD 6 game. It is not simply, “Can this defense survive?” It is, “Can this defense create enough income, deal focused Boss damage, handle the Boss mechanic, and still clean up the rest of the track?” A strong Boss build has a job for every major purchase.
