Monkey Knowledge main menu as featured in Version 1.0.1, featuring 6 categories of upgrades
Monkey Knowledge is an enhancement system in Bloons TD 6 that allows the player to unlock incremental improvements for their towers. There are 6 different upgrade trees for Primary Monkeys, Military Monkeys, Magic Monkeys, Support Monkeys, Heroes, and Powers. Each tree features many different upgrades and perks that can be unlocked with Monkey Knowledge Points.
Starting from Level 30, every level up will reward the player with 1 Knowledge Point to use. Some upgrades require a certain amount of points to be spent in the tree before being unlocked and are lower on their tree. Previous upgrades have to be unlocked to unlock upgrades further down the tree that are more powerful. More Knowledge Points may be earned through achievements, and it takes 133 points to unlock all of the upgrades.
It is possible to immediately reach Level 30 by going to the Monkey Knowledge menu and buying the purchase that unlocks Rank 30 immediately to start earning Monkey Knowledge. However, it costs $9.99 USD, and level 30 can often be reached very quickly so it is generally not advised. A single Monkey Knowledge Point can also be purchased for $0.99 USD.
Monkey Knowledge can be toggled on or off. This can be helpful for testing towers or for practicing C.H.I.M.P.S. mode. A respec option allows the player's Monkey Knowledge to be reset for a cost of 2,000. Using this will refund all spent Monkey Knowledge Points so players can assign them to other Knowledge, and any Monkey Money invested in a Knowledge Point does not need to be reinvested.
In Version 15.0, a change was made where the fourth row of upgrades and further would also require Monkey Money to be purchased. This was done to balance out more powerful Monkey Knowledge upgrades and force the player to either consider buying the Monkey Knowledge point or save up their Monkey Money for other purposes.
The Monkey Money requirements for each knowledge point increases per row, with the fourth row of points costing 250, the fifth costing
500, and the sixth costing
1,000. Subsequent rows are fixed at the same price as the sixth row. Unlocking Monkey Knowledge points from the lower rows of a tree after purchasing a respec will not charge Monkey Money if those points had been unlocked previously.
Knowledge Rewards[]
It costs one Knowledge Point to access a new upgrade. For further upgrades, it may require a specific number of points already invested in that tree before unlocking the upgrade, so note them in the tables.
(The "Requires X Points" statement can be ambiguous. It means that a certain number of Monkey Knowledge must be invested in a specific Monkey Knowledge group in order to unlock the upgrade that requires X points, not that it can be unlocked upon the Xth investment into the specific Monkey Knowledge group. For example, "Requires 3 Points" means that there has to be at least 3 Monkey Knowledge Points invested above the displayed requirements line.)

Trivia[]
- It costs a total of
33000 to unlock all Monkey Knowledge as of version 30.0.
- The Engineer Monkey was the icon for the support tower knowledge even before it was added to Bloons TD 6.
- "Big Bloon Sabotage" is the same name of the Monkey Lab upgrade in Bloons TD 5. It retains a similar effect, reducing the health of the MOAB-class bloons.
- In order to obtain all upgrades for all the categories of Monkey Knowledge, the player must achieve Level 155, assuming that no extra packs have been purchased or earned from achievements or other sources.
- "Weak Point" is the only Monkey Knowledge that requires all other Knowledge in the tree in order to unlock it.
- "More Cash" is the most expensive Monkey Knowledge in the game, requiring a total of
4,500 invested in the Primary tree to unlock.
- It takes a bare minimum of 14 Monkey Knowledge Points to unlock "More Cash" in the Primary tree.
- One possible method to do so is to purchase Fast Tack Attacks, Increased Lifespan, Extra Dart Pops, Fast Glue, Crossbow Reach, More Splatty Glue, 4 And 4, Cheap 'Rangs, Aviation Grade Glue, Master Double Cross, Cheaper Solution, Come on Everybody!, Bonus Glue Gunner, Bonus Monkey!, and then More Cash in that order.
- It takes a bare minimum of 15 Monkey Knowledge Points to unlock "Big Bloon Sabotage" in the Military tree.
- It takes a bare minimum of 9 Monkey Knowledge Points to unlock "Mana Shield", and 10 to unlock "Tiny Tornadoes" in the Magic tree.
- One possible method to unlock it is to purchase Lingering Magic, Magic Tricks, Speedy Brewing, Mo' Monkey Money, Hot Magic, Flame Jet, Arcane Impale, and then Mana Shield in that order.
- The "Violent Impact" Monkey Knowledge was formerly deemed more harmful than good since Bloon Impact/Bloon Crush stuns could not refresh upon a new stun. This was changed as of Version 8.0, since now those upgrades can refresh their own stuns.
- The "Naval Upgrades" Monkey Knowledge essentially turns the Monkey Buccaneer's main dart attack pierce and grape pierce to what it was in BTD5: 5 pierce per dart, and 2 pierce per grape.
- 10 Knowledge Points can be bought for $7.99 USD, while 1 MK Point can be bought for $0.99 USD.
