Pin is the Engineer Monkey's path 3 tier 2 upgrade in Bloons TD 6. Nailgun shots can now pin Bloons not considered Heavy or MOAB-Class, causing the next layer to be stunned for 1 second. Sentries cannot pin bloons unless crosspathed with Sprockets or above.

Pinned bloons are marked with nails embedded on them. Because pinning is technically a type of "stun", affected bloons take more damage from attacks that do more damage to stunned targets.

Strategy

This strategy section is empty or incomplete. See the strategy guidelines for more information on how to write strategy sections.

Pin is a helpful mid-game crosspath to stun Bloons below Ceramic. This is mainly a benefit to the main Engineer, because at least Sprockets is needed to allow sentries to pin.

Both 3-0-2 and 4-0-2 assist mid-game cleanup. 5-0-2 usually doesn't need the lower-tier stun unless on a difficult map format during mid-game.

For Cleansing Foam, Pin assists the slowdown of bloons, with the foam slowing all non-blimps including Ceramics by 50% briefly.
