Ready to complete CHIMPS on the Polyphemus map and earn the Black Border? This strategy is reliable, beginner-friendly, and fully CHIMPS-legal, requiring no Monkey Knowledge, Powers, or complicated micro. By combining a powerful Elite Defender core with Druid scaling and late-game spike support, you’ll safely clear every round all the way to Round 100.
Start by placing a Druid, then place a Sniper Monkey.
Bring Obyn Greenfoot into the game — feel free to use his abilities to get through the early rounds faster.
Place a Monkey Village and upgrade Path 3 twice to get discounts on your purchases.
Using the Village discount, upgrade the Sniper Monkey to 0-2-2.
Then unlock the Semi-Automatic upgrade.
Before Round 40, upgrade the Sniper Monkey to Full Auto Rifle and upgrade the Monkey Village to Jungle Drums to increase your attack speed.
Place an Alchemist to buff the Sniper Monkey and upgrade it to 4-2-0.
Upgrade the Sniper Monkey to Elite Defender.
Upgrade your Druid to 4-0-2 and start saving up for the Monarch of Storms upgrade.
Upgrade the Druid to Monarch of Storms.
Before Round 96, place a Spike Factory and upgrade it to 2-0-5. That’s it!
With this setup online, Polyphemus CHIMPS becomes extremely stable, even during difficult late-game rounds filled with fortified DDTs and massive ceramic rushes. The combination of Elite Defender, Monarch of Storms, and Perma-Spike provides excellent coverage against every bloon type. Follow the upgrade order carefully, and your Black Border is guaranteed.
