The Best Strategies to defeat Bloonarius in Bloons Tower Defense 6

gamepur.com:

Bosses within Bloons TD6 are consistently a harrowing experience, even for veteran players with multiple franchise titles under their belt. Bloonarius is one such boss, awakened from the swampy depths of Sunken Columns.

This doesn’t mean that simply playing the specified map will spawn Bloonarius. Instead, players will need to wait for this boss to appear in the challenge rotation, found on the right side of the main menu screen. Further, all bosses should be noted as extremely difficult. Before attempting, players will want to ensure that they’ve specialized in primary monkeys through the Monkey Knowledge tree, also found in the main menu.

Players have a couple of options regarding how they want to approach this boss. Options are available for standard gameplay, which allows the Double Cash option to be enabled, Ranked gameplay which removes Double Cash option, and Elite which increases the boss health, although this is only available after clearing Bloonarius once. All gameplay modes removes some monkeys from being used for this challenge, such as the Mortar Monkey or Sniper.

If using the Double Cash option, Bloonarius becomes far easier — if not, players will want to ensure that they’re covering two specific areas. Focus on both stacking damage at the top of the arena, while placing Wizard Monkeys with x-x-4 for the Necro option near the bottom for backdoor protection. In Ranked, placing a farm within the first 15 rounds can ensure there is enough funding to provide upgraded towers by the time Bloonarius arrives.

Bloonarius is the slowest moving boss within Bloons TD6, but he comes with an equally large health pool.
