- Official description

Bloons Tower Defense Battles, commonly abbreviated as "BTD Battles", is the competitive multiplayer version of Bloons Tower Defense 5. Gameplay is 1v1 online multiplayer, and the player's goal is to have their opponent lose all of their lives. Income is automatically generated every six seconds (there is no money gained for popping bloons), and income can be increased by sending bloons in Assault Mode or purchasing more income in Defense Mode.

The main menu of Bloons Tower Defense Battles has 5 options:


 * Quick Battle: Searches for a random opponent to play against.
 * Private Battle: Lets the player create battles and join battles created by other players, but only if the Battle ID is known by the joining player.
 * High Scores: Checks the leaderboard for the highest battle score.
 * Upgrades:
 * Towers and their Tier 4 upgrades can be purchased here using Medallions.
 * Bloons Decals, essentially decoration for bloons, can also be purchased with medallions.
 * Powers are upgraded here
 * Store: Brings up the Store, similar to the Premium Store in Bloons Tower Defense 5.

A sequel based on the mechanics of Bloons TD 6, teased on 10 March 2021, has been confirmed to be in development. Just like Bloons TD 6, it will be exclusive to Mobile and later on Steam.

Bloons

 * Most bloons have an income change, increasing or decreasing the player's only initial source of extra money, besides Banana Farms and tier 1-x Cobras in the game, the Eco power section which contains multiple ways to improve eco, and a 6-second income boost.
 * Thus, as the player obtains no money from popping bloons (unless they have the power rubber to gold, which is a 15-second boost that gives you $3 per pop), it is important to constantly improve their income by sending bloons.
 * In Defend Mode, on the other hand, the player's only way of improving their income is by purchasing periodic income boosts.
 * In Assault Mode, you start off with $250 income and $650 right off from the get-go. This means that you will get $250 per 6 seconds. By spending money to send out bloons at your opponent, you can increase the amount of money you get every 6 seconds. For example, if you send out 8 grouped red bloons, your income will increase by $1.
 * As rounds progress, stronger and stronger bloons get unlocked, meaning that you will have to improve your defenses. For instance, spaced Pink Bloons are unlocked on round 4, and spaced Black Bloons are unlocked on round 6.
 * Bloon sends can be Regenerating or Camo or both. These modifiers are unlocked on round 8 and 12 respectively. Changing bloon types this way will incur an additional multiplier on the cost of the bloon. For instance, the cost multiplies by ×1.5 and ×3 respectively, or ×4.5 if both are applied. Adding bloon modifiers will not increase the amount of money per 6 seconds, so do consider the opponent's weaknesses before sending any bloons with different modifiers.
 * MOAB-Class Bloons and fast-cooldown Ceramic Bloons reduce the amount of cash per 6 seconds.
 * A helpful tip for most games is to use grouped bloons, as spaced bloons take longer to send.
 * Grouped Pink Bloons are the fastest bloons sendable, and are thus a great way to quickly gain income.

Towers

 * Upon playing the game for the first time the Dart Monkey, Tack Shooter, Sniper Monkey, Ninja Monkey and the Bomb Tower will be unlocked. Note that their Tier 4 upgrades are locked, and must be purchased with medallions.
 * The next towers, which are unlocked upon reaching a 50, include the Ice Tower, Boomerang Thrower, Glue Gunner and Monkey Buccaneer. Unlike the towers you get from the start, you must pay a small amount of medallions (usually 10-25) to unlock them, as well as additional medallions for their respective Tier 4 upgrades.
 * The third tier of towers are unlocked upon reaching 250. These are the Monkey Ace, Mortar Tower, Spike Factory and Dartling Gun. Again, they must be purchased for use in battling along with the separate Tier 4 upgrades.
 * The final tier of towers, unlocked upon reaching 500, include the Super Monkey, Monkey Apprentice, Monkey Village, Banana Farm, Bloonchipper, and Monkey Sub. As stated before, you must gain higher battle score to unlock higher tiers.

Rounds
Rounds are mostly the even-only equivalent of those in Bloons Tower Defense 5, with only a few exceptions. For instance, Round 43 represents Round 85 of BTD5 instead of 86, and Round 12 that is Round 25 of BTD5 instead of 24. However, in the iOS version, the rounds are from the Flash rounds -1, so Round 12 is Round 24 of BTD5 instead of 25. Round 43 is the only round not to follow this rule, as it contains the normal round 85. As a result, dangerous bloons like M.O.A.B Class Bloons appears less and later on mobile. However, version 3.1 on mobile made short rounds had more bloons so the player can react better. M.O.A.Bs from the computer come at round 23 (27 on mobile), but it is possible to send them at round 18.

Beware that even though mobile rounds are easier, there are still two "ceramic rush" rounds on both versions: 38 and 39 on Flash and 28 and 32 on mobile and Steam.

A round only begins 4 seconds after one player has popped all computer-generated bloons in the previous round, or 8 seconds after all the natural bloons have been spawned, whichever occurs earlier.

Other features

 * 1 is recovered every 12 minutes.
 * Medallions appear to be much like the Bloons Tower Defense Battles version of the Bloons Tower Defense 5 Monkey Money used to buy Towers and Bloon Decals in the Shop/Towers & Bloons menu.
 * The player earns 2 for losing (0 for disconnecting or surrendering on the first 13 rounds), 5 for a win, and 7 for a flawless win (7 for a flawless win is only available in the mobile version).
 * 10 is awarded for winning. Losing rewards 2.
 * There are 2 "abilities" to use during the thirty-second time before battles: the spy and an extra tower slot. The spy costs 2 and let you see the opponent's towers and the extra tower slot costs 1 and let you choose 1 extra tower for a total of four towers.
 * In the mobile edition, the bonus is chosen randomly by a roll and can be any tower, even towers you didn't yet unlock (your bonus is Tier 4). Rolling costs 1 and rerolling costs 3. Spying requires 2, and exiting either an Assault or Defend game also costs 2, counting as a loss.
 * The player can choose between Assault and Defensive Mode.
 * In Assault Mode, the player attempts to crush their opponent with bloons, similar to the Bloons Tower Defense Battles before the update with defend mode. After Round 30, all player-sent bloons will have their speed boosted by 20% each wave. Sending bloons also affects the player's income.
 * In Defend Mode, the player attempts to outlast their opponent. They cannot send any bloons, and have an initial income of $60. It can be increased by purchasing income boosts, which have a cooldown based on the income increase; the higher the boost, the longer the cooldown, but also the more cost-effective the boost is. Income is capped at $3,000.
 * Small income boost - Increases income by $2. Cost: $50. Takes 150 seconds to "break even", as in, pay for itself. Cooldown is 3 seconds.
 * Medium income boost - Increases income by $15. Cost: $300. Takes 120 seconds to break even. Cooldown is 15 seconds.
 * Large income boost - Increases income by $70. Cost: $1,000. Takes approximately 90 seconds to break even. Cooldown is 60 seconds.
 * Huge income boost - Increases income by $700. Cost: $7,500. Takes approximately 66 seconds to break even. Cooldown is 180 seconds.
 * MOAB-class bloons gain 20% speed and 40% health per wave after round 30.
 * Selling towers returns 70% of the purchasing price rather than 80%.
 * There are battle arenas (Mobile only), where both players play for an increased medallion entry cost. The combined entry cost then becomes the prize pool, all of which goes to the winner. Some arenas have preset custom gameplay rules, such as doubled income, or upgrading all existing towers or bloons with the boost. Other arenas require club access to play, but occasionally give free runs.
 * In-game chat and the Dartling Gun were added to Bloons Tower Defense Battles in the same update that added the track Hydro Dam to the game. To chat a player must press enter and type the message. However, there is no chat for Bloons Tower Defense Battles Mobile because there is no usage of the keyboard in the mobile version. Instead, there is a selection of faces and quotes. Press enter again to send it. The /ping command can be used in the chat also to determine the ping speed.
 * A later update added a feature called Clans (Mobile only). Clans are collections of players that help each other out.

Trivia

 * The main menu of this game is interactive. Scrolling over any of the monkeys on the game's logo will cause them to move:
 * Scrolling over the Sniper Monkey will make it aim its gun as if it were going to shoot. After about 2 seconds it will shoot and it will fire subsequently every 2.5 seconds after that.
 * Scrolling over the Super Monkey will make it use its laser vision.
 * Scrolling over the Ninja Monkey will make it disappear into a puff of smoke. A log appears in its place after this.
 * This does not work on portable version however
 * In portable and PC version, when your opponent forfeits a battle, the energy spent to enter the battle is refunded.
 * On the screenshot that shows that a hacker of the game has been detected, a Dart Monkey with a troll face is shown.
 * It is not available on Kongregate.
 * The first ZOMG that appears naturally (not sent) has 20800 health instead of the usual 4000. That makes it stronger than a B.A.D. from BTD6 and BATTD. That happens because MOAB-Class bloons get stronger and faster every round starting at round 30.
