Bloons TD Battles Dartling Farm Boomer Strategy Guide

To win with the Dartling Farm Boomer (Dartling Gunner, Banana Farm, Boomerang Thrower) loadout in Bloons TD Battles, place your Dartling Gunner at the end of a long straightaway, greed early Banana Farms, upgrade reactively to 2-3 Hydra Rocket Pods by Round 13, and rely on an 0-4 Turbo Charge Boomerang for Round 18 MOAB defense.

This loadout requires precise manual targeting and disciplined bankroll management. It trades automatic target tracking for high pierce and heavy burst damage, making it strongest on maps with long, linear lanes.

Early-Game Setup and Targeting

Place your initial Dartling Gunner so its firing line shoots directly down a long, straight track segment. Dartling projectiles rely entirely on line pierce; diagonal or cross-lane placements waste darts against early spaced or grouped bloons.

Deploy Dartling Gunner (0-0): Aim down the longest available straightaway to pop grouped reds and blues.
Build Farm 1: Drop a 0-0 Banana Farm immediately, upgrading it to 1-0 as soon as cash allows.
Upgrade to Powerful Darts (2-0): Keep the Dartling at 0-0 or 1-0 until bloon density threatens leaks, then purchase 2-0 to boost pierce and damage.
Manual Reticle Control: Steer your cursor slightly ahead of incoming bloon packs. Avoid locking the reticle in a fixed position, as fast bloons like spaced pinks will leak if the stream fails to lead the target.

Mid-Game Rush Defense

Between Rounds 10 and 13, opponents will test your defense with grouped leads, zebras, and regrow rainbows. Do not sink all your cash into farms during these rounds; hold liquid cash to react to incoming sends.

Round & Incoming Threat	Minimum Defensive Upgrade	Action
Rounds 8–10 (Grouped Yellows / Leads)	2-0 Dartling Gunner + 0-0 Boomerang Thrower	Aim directly down the lane; add a Boomerang Thrower if bloons breach the Dartling stream.
Round 12 (Camo / Fast Pinks / Leads)	2-2 Dartling Gunner	Ensure Point Five Oh and lead-popping power are ready before camo sends arrive.
Round 13 (Regrow Rainbow Rush)	2-3 Hydra Rocket Pods (or 2-3 Boomerang clean-up)	Pop a Tower Boost immediately and aim rockets directly at the front of the rush cluster.
Round 18 (Fast MOAB Send)	0-4 Boomerang Thrower (Turbo Charge)	Trigger the Turbo Charge ability to break the blimp layer, then clean up ceramic insides with rockets.

Hydra Rocket Pods (2-3) pop both lead bloons and clustered regrow packs with explosive damage. If an opponent sends an unusually dense, layered rainbow rush, pierce exhaustion can cause leaks. Place a 2-3 Boomerang Thrower (Glaive Ricochet) at a central bend to bounce through inner layers and catch bloons that escape the primary rocket barrage.

Farm Progression and Emergency Selling

Snowball your economy by upgrading existing farms rather than immediately placing excess unupgraded plots. Always maintain an $800 to $1,200 cash buffer to react to sudden sends.

Step 1: Upgrade your first Banana Farm to 2-0.
Step 2: Place a second Banana Farm and upgrade it to 2-0.
Step 3: Upgrade farms to 3-0 Plantations only when the track is stable and your cash reserve remains intact.

If an opponent launches a massive all-out rush that exceeds your current damage output, sell your farms immediately. Banana Farms sell for 70% of their total invested value. Use this liquid cash to purchase an emergency 0-4 Dartling Gunner (Rocket Storm) or a 4-2 Boomerang Thrower (Glaive Lord). Surviving the rush takes priority over passive income.

Defending MOABs and Counter-Attacking

Handle mid-to-late-game air threats with Boomerang abilities:

Round 18 MOABs: Place a Boomerang Thrower near an intersection or curve so its throwing path clips the blimp repeatedly. Upgrade to 0-4 (Turbo Charge) and activate the ability the moment the MOAB enters range. Once the shell breaks, direct your 2-3 Dartling rockets onto the ceramic children.
Round 20 BFBs and Round 22 ZOMGs: Chain multiple Turbo Charge activations with Rocket Storm ability barrages to strip outer layers before bloons reach the final track bends.

Watch your opponent's side of the screen while defending. If they overcommit cash to a high-tier farm or buy an expensive late-game tower without keeping reserve funds, immediately send a tight, layered rush—such as regrow zebras over ceramics. Forcing their Tower Boosts leaves them defenseless against a dedicated Round 20 BFB or Round 22 ZOMG push.
