Bloons Blitz Level 3 Strategy: Placement, Upgrades, & Target Settings

To clear Level 3 in Bloons Blitz, anchor your initial tower setup on inner track bends, configure your lead defenses to target heavy targets, and spend early gold on direct damage upgrades instead of high-tier unit unlocks.

Tower Placement on Track Curves

Positioning towers at the inner vertices of track bends provides dual-angle coverage. Towers in these spots fire on Bloons as they enter the turn and continue attacking as the Bloons exit, maximizing coverage time per unit.

Avoid placing starting towers along long straightaways. Straight track segments limit attack windows and force towers to rotate frequently, reducing total damage uptime during fast early waves. Before confirming a placement, check the tower's range indicator to ensure its coverage overlaps at least two distinct track segments.

Upgrades and Gold Management

Level 3 increases spawn density early in the stage, making early gold management critical:

• Prioritize Stat Upgrades: Invest gold into range and attack speed upgrades for base towers immediately. Upgrading existing towers yields faster, cheaper power spikes than saving for expensive tier-three or tier-four units.
• Watch Wave Indicators: Monitor the wave counter in the top-right corner of the screen. When a dense wave approaches, focus gold on enhancing existing towers rather than buying new ones.
• Add Pierce for Groups: If single-target towers get overwhelmed by dense waves in the late round, upgrade their pierce capacity to deal damage to multiple Bloons simultaneously.

Configuring Unit Targeting Priorities

Assigning target modes prevents towers from wasting high-damage attacks on weak targets while tougher Bloons pass through.

Setting forward towers to "Strong" and rear towers to "First" or "Close" creates a fail-safe funnel that maintains line integrity against high-density waves.
