Round 75 (BTD6)

Round 75 is a round in Bloons TD 6. It is the sixth-to-last round on Hard Difficulty in BTD6. On this round, there are many Leads, extremely tight BFBs, and some Fortified MOABs.

Description
Some spaced Leads spawn, then four BFBs come in. Fortified MOABs come in with small spacing. Fortified Leads then spawn too. Three BFBs with no spacing will approach.

Strategy
This is one of the most difficult mid-game rounds, alongside notorious rounds such as Round 63, Round 76, and Round 78. However, this round stands out because of the many BFBs on this round accompanied by many Leads that may block typical defenses reliant on Acidic Mixture Dip buffs. A lot of grouped MOAB-class popping power plus reliable lead-popping power is required to beat this round effectively.

This round may be in fact easier on maps with multiple paths, as the last BFB rush will be divided among the paths.

Tips

 * If using Etienne's UCAV ability to defeat Round 75's BFBs, make sure that the round is finished as quickly as possible, so that the UCAV carries over to Round 76, which it will quickly defeat.
 * MOAB Maulers deal effective grouped blimp damage, attack pretty quickly, and thus are ideal for the densely clumped BFBs. Having a moderate group of them can easily beat the additional MOABs too.
