Ninja Kiwi released Bloons TD 6 in June 2018 and has kept adding to it ever since, past 25 monkey towers split across the Primary, Military, Magic and Support categories. Every tower has three upgrade paths of five tiers, but you may only take two paths and the second one caps at tier 2, which is the single rule that shapes every strategy in the game. Rounds run to 100 in standard play, with the MOAB arriving at 40, the BFB at 60, the ZOMG at 80, the DDT at 90 and the BAD at 100.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
