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.

In December 2015, Bounty Cards were added on mobile devices, arriving on Early December 2015 and Late December 2015 to Android and iOS devices respectively.

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 tile that is rated Easy or harder. 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 7.2 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 enhance certain strategies

 * Dart Monkey: Free Dart Monkeys may be used as extra helpers of hitting Boss Bloons.
 * Bomb Shooter: Smaller footprint allows packing of greater numbers of MOAB Maulers into a single Monkey Village's radius.
 * Dartling Gun: Many of the ranks for the Dartling Gun will help greatly when fighting in Boss Battles, when Dartling Guns are used in large packs.
 * Banana Farm: Ranks 4, 5, 9, 10, 14 and 15 allow Monkey Banks to be more valued for their upgrade costs.
 * Monkey Engineer: Camo detection to sentries allows them to be used as cheap Enhanced Eyesight Dart Monkeys.
 * Activated Ability: Ranks 3, 4, 5, 8, 9, 10, 13, 14 and 15 may allow some players to exploit them only for the sake of enhancing towers temporarily or gaining free lives/cash/stunning.

Upgrades that may prevent certain strategies

 * Boomerang Thrower: Increased projectile hit area/speed can prevent certain tactics from working. This may affect upgrades such as Glaive Riccochet, especially with the increased hit area, because it may make glaives riccochet the way the player did not intend to do. However, it may strongly help non-Riccochet Boomerang Throwers as it will help ensure accuracy of hitting the bloons, particularly Fast Bloons.
 * Sniper Monkey: Increased layer damage can hinder Supply Drop Farming. This may reduce the amount of time of the round and hinder the number of times that the player can seize the use of 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).
 * Bomb Shooter: Zebra/black popping could harm Supply Drop Farming if used as a Regrow multiplier, which a Cluster Bomb Shooter's part of Supply Drop Farming contributes to increasing the numbers of Zebra and Black Bloons in order to multiply the numbers of Regrow Bloons.
 * 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.
 * Bloon Sabotage: Bloon Sabotage's reduction in MOAB-class bloon health may make Bloonarius spawn bloons sooner and not yield enough cash for the player to counter its spawned bloons. This may also hinder the Monkey Pirate to make it cool down and pull down the MOAB or BFB children of Bloonarius in time. However, it does not too much matter too much as by the time the Bloon Sabotage goes up to Rank 5 (15% less MOAB-class health) from Rank 0, the player may have gone up at least fifteen levels up by then.
 * Monkey Village: Increase of granting range may make enhanced Spike Factories to not concentrate better on a smaller area. However, it may help Spike Factories actually reach further, in certain tracks. It also affects Engineers under the range of a Monkey Village as it will make Cleansing Foam and Bloon Trap stray to a part of the track where the player may not want, such as near the exit.

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. Another example includes the Sniper Monkey's Legendary Card having the Cripple MOAB upgrade icon instead of what would normally come after the Semi-Automatic Rifle, the Supply Drop Sniper Monkey.
 * All Bounty Cards except the Monkey Secret turn blue with a black "Knowledge Card Face", including some diamond sort of shapes around, which also has some "bling bling bling" sounds. Such sounds are also heard when collecting the card.
 * The Monkey Secret Card turns black (not blue) and becomes animated in the way the Rare cards do, except the color scheme being black instead. It bulges much more.
 * Once collected, it will twist and turn around anti-clockwise faster and faster and showing a series of legendary card face covers in random order, also showing "+250" including or not including "Rank Up" (if a book ranks up). Black electricity also pulses from wild directions and at wild times, as well as sometimes the card turning blue, covering the tower faces. Once the last tower is done, which in this case will always show the Legendary Activated Ability icon (normal Activated Ability icon in mobile), the card disintegrates and its blue sparkles gets added to a special Monkey Secret Book (as the secret applies to all towers).
 * 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.
 * On Mobile, several Ranks do not actually have the said effect during Tile captures, CTs and Boss fights:
 * Tack Shooters on Ranks 3/8/13 have a 50% chance of shooting a +1 pierce tack.
 * Snipers on Ranks 3/8/13 have a 50% chance to pop one extra layer.
 * Bomb Shooters on Ranks 5/10/15 have a 33%/66%/100% chance of popping Black and Zebra Bloons.
 * Rank 10 Ninja Monkeys have a 50% chance of throwing 7 shurikens instead of 6.
 * Each Sentry from a Rank 13 Monkey Engineer has a 33% chance of popping Lead Bloons.
 * Airburst Darts from a Monkey Sub on Ranks 3/8/13 have a 33%/66%/100% chance of releasing four darts.
 * In BMC Flash, each animation of each card rarity goes like this:
 * In Common Cards, it is a card turning green, some green poof, then turning the card over. Chirping of birds is heard.
 * In Uncommon Cards, it is a card turning red, some flames coming out and pushing forwards a little bit, then turning the card over. Flame burning sounds is heard.
 * In Rare Cards, it is a card turning purple, some pulses of purple electricity comes out and the card pushing forwards, then turning the card over. Electric pulse sound effects followed by what sounds like a laser is heard.
 * In Legendary Cards, it is a card turning moderately yellow, some pulses of bright yellow electricity and the card pushing forwards very much, then turning the card over. A more intense version of the Rare Card sound effects is heard, except the "laser" sound is replaced by a "hoh" choir sound effect.
 * With regards to Ranks 4, 9 and 14 for the Boomerang Thrower, the boomerang size also increases in size.
