If you’re aiming to secure the Black Border on the iconic Flooded Valley map, this smooth and reliable CHIMPS route will take you all the way from Round 1 to Round 100 with zero RNG and precise, repeatable placements. The strategy is built around strong naval power, high-value upgrades, and perfectly timed Tier 5 transitions.
- Begin the run by turning off Auto Start and placing two Sub Monkeys immediately. These will comfortably handle the early rounds and give you the stability you need before your main carriers come online.
- Bring Silas into the game and freely use his abilities to keep the early waves safe and consistent. Then place a Mermonkey along with a Monkey Buccaneer, which will become your primary damage dealer as the game progresses.
- Upgrade the Monkey Buccaneer to 2-2-0, starting with Path 2 to boost its early efficiency. Continue upgrading it into a Destroyer, giving you a major power spike that easily clears the mid-game rounds.
- Before Round 36, upgrade your Mermonkey to 3-0-2, and before Round 40, advance it to Abyssal Warrior. With these upgrades, the map’s toughest early threats are neutralized.
- Place a Monkey Village and upgrade it to 4-2-0 to power up your core towers. From here, transform the Buccaneer into an Aircraft Carrier, then push it further to Carrier Flagship, unlocking one of the strongest naval anchors in the game.
- Upgrade the Mermonkey to Lord of the Abyss, giving you overwhelming late-game strength.
- On Round 85, place an Ice Monkey and upgrade it to 5-2-0.
Before Round 96, place an Engineer Monkey and upgrade it to 5-0-2.
Before Round 100, place a second Ice Monkey and upgrade it to 0-5-2.
With this lineup fully online, victory is guaranteed, and the Black Border for Flooded Valley is yours without needing luck, powers, or Monkey Knowledge.
