How do I beat Bloons TD 4?
There is no official walkthrough, but the community shape is consistent across tracks: open with one upgraded damage tower, add a Banana Farm early for income, push upgrades before buying more towers, consolidate into a Sun God for the final rounds, and hold with a Spike Factory.

Evidence: community
What is the best strategy for Bloons TD 4?
By player consensus the strongest, simplest strategy is economy first: a Banana Farm bought as soon as the line is safe, one damage tower pushed through its upgrades instead of spreading across many, and a Sun God — with a Spike Factory as insurance — for the late rounds. Full reasoning is on the beginner guide and best-towers pages.
