Monkey Knowledge Packs

 are items in Bloons Monkey City. They can be obtained by capturing Tiles, opening Treasure Chests, game events (such as Festival of Bloonstones) or from Contested Territory milestones and occupation. These special packages contain Cards which give XP to a Monkey Knowledge Book. If a card gives XP to a Monkey Knowledge Book to a tower that is maxed out, the rest of the cards XP will convert to coins equal to 100x times the amount of experience the card would normally give.

This is also available on mobile, being soft-released for Android on September 17, 2015 and fully released for iOS on September 21, 2015.

Obtaining Monkey Knowledge Packs
To get Monkey Knowledge Packs the player's city must be at least Level 12. They can be obtained in both cities.

Tiles
There is a 33% chance of obtaining one common Monkey Knowledge Pack from completing a normal tile. Neither NLL nor Hardcore mode will affect this chance. During the Monkey Knowledge Madness event, the chance is boosted to 100%. During a Monkey Teams event that gives Knowledge Packs, you can gain another Pack in addition to the one earned by normal means or through the Monkey Knowledge madness event.

Bloon Beacon
When a player captures a Bloon Beacon tile, you will always obtain a Monkey Knowledge Pack. You can still obtain a normal Monkey Knowledge Pack from capturing tiles in addition to the forced Knowledge Pack. When certain events are active such as Monkey Teams or Monkey Knowledge Madness that give a Knowledge Pack upon completion of a tile and complying with the event's rules, you can gain an additional Knowledge Pack. A Bloon Beacon Tile only comes once every six hours but you can get one instantly if you pay 50. As of about 10th December 2015, every 6 minutes you wait for the Bloon Beacon to recharge will force you to pay one less Bloonstone if you want it to instantly recharge, up to a minimum of 1.

Wildcard
A Wildcard has the same chance to occur as all other upgrades. It can be used to give XP to the Monkey Knowledge Book of your choosing. They have the same chance to appear as any other card, and are always granted in Wild Card Packs.

Upgrades that may prevent certain strategies

 * Boomerang: Increased projectile hit area/speed can prevent certain tactics from working.
 * Sniper: Increased layer damage can hinder Supply Drop Farming. This may reduce the amount of time of the round and hinder the number of chances to use the Supply Drop Ability.
 * Apprentices/Mortar Towers: Regrow removal can harm Supply Drop Farming (although you could aim the mortar away from track, and the Apprentice seems to still regrow farm).
 * Super Monkey: Increased base tower range can harm the players ability to place multiple temples close to each other (but you can only place up to six temples anyway).
 * Ice Monkey: Zebra/white popping could harm Supply Drop Farming if used as a regrow loop booster (especially as an Arctic Wind, although you could use Glue Hose).
 * Most towers & Monkey Tycoon: Discounts on base cost & upgrades may make more towers necessary for temple sacrifices. However, discounts may make players be able to buy towers and upgrades sooner. Fortunately, there is also the "Temple sacrifice uses (+10%, +20%, +30%) more worth of each contributing monkey" ranks, which may help counter the discount issue.
 * Monkey Buccaneer: the +1 grape from Grape Shot attack apparently causes a much higher miss rate for a single x/1+ Monkey Buccaneer on curved paths when attacking loosely packed bloons, especially if having to work solo when it is not a Destroyer. It works better with the extra grape on straight lines, though (Grape follows the dart, so two layers at a time). The main reason for the disadvantage is because the outer grapes go more angled when the +1 grape is unlocked.

Trivia

 * It's possible to earn six Monkey Knowledge Packs on a single tile. To do this you have to have a Bloon Beacon spawn on a Treasure Chest (which have a chance of giving both a regular and ancient pack together), have a Monkey Teams event that gives Knowledge Packs, and get lucky and have a normally obtained Knowledge Pack be obtained as well. You can get a sixth one with Mini-Land-Grab.
 * The monkey's appearance on rare and legendary Activated Ability Monkey Knowledge cards is a reference to the Kaio-ken ability and Super Saiyans from the Dragon Ball manga and anime series.
 * The flames given out in the Common and Uncommon Activated Ability Cards are a reference to the fighting technique Kaio-ken, as seen in Dragon Ball manga and anime series.
 * Regrow removal from mortar works only for bloons it can pop (so no zebra/black regrow removal).
 * All Common cards associated with towers have images of the unupgraded towers.
 * All Uncommon cards associated with towers have images of either one of their first- or second-tier upgrades.
 * All Rare cards associated with towers have images of either one of their third-tier upgrades. (The only exceptions are the Tack Shooter, which gives a picture of the Even Faster Shooting upgrade, the Banana Farm, which gives the Banana Plantation artwork, and the Monkey Ace, which gives the Spy Plane artwork)
 * All Legendary cards associated with towers have images of either one of their fourth-tier upgrades. They may usually follow the same path as the tower's Rare Card, but there may be a few exceptions. One example is the Bomb Shooter's Legendary Card depicting a MOAB Assassin even though the Rare Card depicts the Cluster Bombs upgrade.
 * The BMC Mobile Monkey Knowledge Cards are always the same across every card.
 * All cards associated with towers are at the unupgraded stage.
 * The Wild Card is always the purple jester.
 * The Bloon Sabotage Card is always the doodled Red Bloon.
 * The Monkey Tycoon Card is always the Monopoly Monkey displaying flying dollar bills.
 * The Activated Ability Card is always the red-banded Kaio-ken monkey powering up a small red flame.
 * In BMC Mobile, if a player receives a Wild Card, the player may hold it until they decide to go to the Monkey Knowledge Books to drag a tower of that player's choice.
 * To open the packs quickly, go and open a box then press close, it adds xp to towers and can immediately open another pack after closing. This acts saves time, especially on wild cards when you do not want to use it yet.
 * In BMC Mobile there is a way to open up packs quickly. Tap to open a pack (tapping exactly on the pack is not neccesary, it's also possible to just tap somewhere nearby) and once all 4 cards are shown the player can swipe a finger from the left card to the right and vice versa to reveal the cards and swipe back to collect them immediatly. Swiping can be done really fast and this takes no more than 5 seconds.
 * Monkey Sub's Airburst Darts actually do not shoot four darts as listed above. It instead grants:
 * 34% chance on Rank 3
 * 67% chance on Rank 8
 * 100% chance on Rank 13
