Tips & Tricks
- Prioritize a Ninja Monkey early to handle camo bloons without spending extra cash on detection upgrades immediately.
- Rush toward the high-damage upgrades on your primary towers by round 15 to ensure you have enough stopping power for the mid-game rush.
- Focus your defense on a central intersection of the map to ensure your monkeys get maximum coverage across multiple segments of the track.
- Save your gold for one powerful tiered tower rather than scattering weak units everywhere, as concentrated fire cuts through lead bloons far better.
