Monkey Knowledge is an upgrade system within Bloons TD6. This menu has upgrade trees for Primary towers, Military towers, Magic towers, Support towers, Heroes, and Powers. Each tree features many upgrades for monkeys that can be unlocked with Knowledge Points. After level 30, every level up will reward the player with 1 Knowledge Point to use here. Some upgrades require a certain amount of points to be spent in the tree before taken 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.
As of Version 2.0.0, Monkey Knowledge can also be toggled on or off.
Knowledge Rewards
The structure of the overall knowledge trees are difficult to understand at first, but with enough patience, it is possible to fully understand them.
It costs one Knowledge Point to access a new upgrade. For further upgrades, it may require a specific number of points in that tree before unlocking the upgrade, so note them in the tables.

Trivia
- The Monkey Engineer is the image for the support tower knowledge, even though it doesn't appear as a tower in the game. However, it has been confirmed to be released at some point in the future.
- "Big Bloon Sabotage" is the same name as a Monkey Lab upgrade in Bloons Tower Defense 5. It retains a similar effect, reducing the health of the bloons. Note that is does NOT decrease the bloons speed.
- In order to obtain all upgrades for all the categories of Monkey Knowledge, the player must achieve level 137, assuming that no extra packs have been purchased or earned from achievements or other sources.
- Certain knowledge points render secondary tower upgrades obsolete, for example the Hard Thorns upgrade for the Druid allows it to pop 2 bloons per shot as well as frozen bloons, however the Magic knowledge point Hot Magic grants all Magic monkeys the ability to pop frozen bloons.
- It is possible to rank up straight to Rank 30 by going to the Monkey Knowledge menu and tapping the option that unlocks Rank 30 immediately. It costs $9.99 USD though, and it's really easy to reach Rank 30 anyway.
