Bloontonium Lab is one of the hardest tracks in BTD5, and is one of the couple Extreme tracks. Its three completely separate short paths that only come close together in the middle makes this extremely difficult to beat, especially on hard. If you don't get up a good defense quickly. M.O.A.B. class bloons will give you massive problems.

It's recommended to at least use the 3-tier Dart Monkey Specialty Building if you're trying to beat the map on Hard. Even though it's not impossible to beat the map on hard NAPS, it'll most likely take you a frustrating amount of attempts and a bunch of monkey money to come up with a NAPS strategy.

Note that the strategies written below won't guarantee a absolutely win, especially on hard difficulty. These are merely guidelines to help you have a general understanding of what you need to do to beat the map.

Map NotesEdit

It is important to note that the bottom path is shorter than the other two due to the aspect ratio of the screen.

Strategy 1Edit

Starting with 6 dart monkeys happens to be a great idea, along with building up many Banana Farms, utilizing the unupgraded Spike Factory to take care of loose bloons and using Corrosive Glue (Upgraded to 2-2) and Lightning Monkey Apprentices to deal with the leads and the rainbows. A Super Monkey should be placed as soon as you have a stable cash flow from your 5-6 Banana Plantations mid-way into the game. Try to build an Arctic Wind Ice Tower in the centre by Round 40+. But to ensure they can detect Camo bloons, a Radar Scanner is also necessary. Higher levels (70+) should generally mean that you should start buying more Sun Gods or Robo-Monkeys. Note that the strategies used for other tracks probably won't work here.

Strategy 2Edit

(Monkey tycoon and double cash advisable.) buy many dart monkeys then sell to get a super monkey with super and epic range, then get a radar scanner ASAP. Buy and sell bionic boomers for lead levels 1 and 2 (not needed on easy) then get robo monkey. DO NOT GET LASER/PLASMA YET!!! Get monkey town/high energy beacon and arctic wind. Get more robo monkeys, then progress on to sun gods. Get 1+ temple of the monkey god. Spike factories for glitch regrowers. Kill ZOMG. Win.

Strategy 3Edit

What may work is a strong tower (Bomb Tower, Monkey Apprentice, Ninja Monkey) in the middle, with many speed and range upgrades, and then Glue Gunners and Ice Towers (You know, towers that slow and stop bloons) around it. Unfortunately, Spike factories will be very hard to work with here, as they are expensive, and where you really need them is at the end. But, you canot place a Spike factory so it can send tacks to the ends of more than one path. You can place one so it can send tacks to the beginning-middle, or middle-end of two, or even the middle of three, but there are very good reasons why those probably will not work, most of the time. First, putting a Spike factory in the center of the track takes up valuable space, and you'll probably just have to sell it when you start working with Super Monkeys. With a Bomb Tower or a Monkey Apprentice, however, you can place them very close to the exact center, and then they can be sacrificed and used for a Temple of the Monkey God, if you make it far enough to be able to afford, place, buy, and use one. Get Super Monkeys as soon as possible. And a trio or quartet of Dart Monkeys inside of each track isn't a bad idea. But remember-make sure you have your strategy completely mapped out before you start, otherwise you could waste lots of Monkey Money.

Strategy 4 (Sam Wang)Edit

Start with 3 dart monkeys. After that, buy 3 more dart monkeys with targeting set to strong in the edge of the middle circle. This is because you will need to save up for a 3/1 bomb tower in the center and target set to strong later. Upgrade the bomb tower to 3/2 and even 4/2 if needed. In the meantime, start buying and upgrading banana farms on the first path until it is upgraded to a BRF, then upgrade it to 4/2. Also, don't forget to put super monkeys (3/2 and 2/3) along with adding more powerful towers. An artic wind is recommended to be placed in the center.

Strategy 5Edit

You need 3 Pro Tribal Turtles and a Portable Lake.

Place your agents in the middle.Place a Triple Darts too.You also need Dart Training Facility Tier 3.Get a Monkey Buccaner.Upgrade it to Destroyer as soon as possible.Get a Super Monkey with a village as soon as possible.Upgrade Super Monkey to Laser Blasts in a few rounds if possible.Upgrade Village to Rader Scanner to make Super Monkey target camo bloons.Upgrade Super Monkey to Plasma Blasts and then Robo-Monkey.Try to get another Plasma Robo-Monkey before first M.O.A.B comes.Win!

A Premium Upgrade is useful and is highly advised if you have enough Monkey Money, and can let you win on Medium.
