Bloons Blitz: How to Clear Level 29

To beat Level 29 in Bloons Blitz, switch your defensive strategy from single-target damage to high-pierce splash towers, multi-lane coverage, and timed hero abilities. Level 29 introduces heavy wave density and grouped balloon surges that can easily overwhelm narrow single-target defenses.

Tower Placement and Targeting Setup

The influx of high-density balloon groups requires thin-out coverage near the track entrance before targets reach vulnerable mid-map defenses.

Cluster Splash Units Near Intakes: Place towers with innate splash damage or pierce upgrades around the initial track entrance to break down dense groups early.
Cover Track Intersections: Avoid placing towers in isolated spots. Position splash damage units at main track intersections and bends so their range overlaps multiple segments of the path.
Adjust Targeting Priorities: Change tower targeting modes based on wave composition. Set targeting to Strong when armored balloons appear, or First when facing fast-moving swarms.

Upgrade Investment Strategy

Prioritize defense breadth and mid-tier efficiency over rushing a single high-tier unit during the first half of the level.

Strategy Focus	Recommended Action	Goal
Gold Management	Upgrade existing splash towers to pierce thresholds before buying new base towers.	Maximizes gold-to-damage efficiency per unit.
Defense Depth	Spread gold across multiple mid-tier upgrades featuring attack speed and pierce boosts.	Prevents total line failure if one unit gets overwhelmed.
Positioning	Nudge tower placement close to track curves to allow multi-angle engagement.	Creates double-pass damage opportunities along loops.

Hero Ability Timing

Saving hero cooldowns for high-density congestion prevents late-stage leaks.

Hold Cooldowns Early: Do not activate hero abilities at the start of a wave. Wait until balloons push past the first quarter of the track.
Target Track Bends: Trigger area-of-effect (AoE) abilities when large enemy clusters concentrate around narrow bends to maximize hit counts.
Counter Heavy Clusters: Use high-damage abilities on armored balloon groups so your regular towers can clear fast secondary targets without distraction.
