Smart Spikes (Directed Spikes prior to version 14.0) is the Spike Factory's path 3 tier 2 upgrade in Bloons TD 6. It gains a tower buff at the start of each round that quadruples its attack speed for 3 seconds. If crosspathed with Spike Storm and Carpet of Spikes, their abilities will only dispense spikes on paths that currently have Bloons on them, and their abilities will dispense more spikes if they're triggered while the buff is still active. The buff can be absorbed by Lych. The Spike Factory also gains three new targeting options:
- Close — Dispenses spikes on the nearest section of track within range.
- Far — Dispenses spikes on the furthest section of track within range.
- Smart — Targets whichever track has the Bloons that are closest to reaching the exit (or has Bloons at all), and dispenses spikes on the point closest to the end of that track. If it cannot reach any paths that have Bloons on them, it will dispense spikes on the points closest to the ends of each track within its range, keeping their coverage roughly even.

- Far targeting no longer causes the game to crash if it cannot reach the track (bug fix)
Now gains a 4× attack speed buff for 2.5 seconds at the start of each round
Name changed ― "Directed Spikes" → "Smart Spikes"- Description changed ― "Spike Factory gains special targeting priority." → "Spike Factory gains special targeting priority and accelerated production at the start of each round."
| “ | Since launch xx2 has never brought enough to the table as a crosspath. Working into the long life trend of the bottom path we felt that introducing longer life at a ‘cross-pathable stage’ may work in some new niche. — Update notes |
” |
- Projectile lifespan increased ― 70s → 100s
- Note: X-X-3 unaffected
- 0-4-2, 0-5-2
- Ability: Projectile lifespan with Long Reach increased ― 9s–11s → 15s–16.5s (50% longer)
- 0-4-2, 0-5-2
- Spike Storm ability: Targets only active paths (e.g. Bloody Puddles)
- 0-5-2
- Passive ability: Targets only active paths (e.g. Bloody Puddles)
| “ | Like a few other towers before it, the attack speed crosspath for Spike Factory has outshined the others. We have reworked the lower Spike Factory tiers to distribute this power more evenly while keeping high tier factories at a similar level of power. — Update notes |
” |
Overall cost increased by $200 (due to cost changes for previous tiers)- Base spike factory rate increased ― 2.2s → 1.75s
- 0-1-2
- Rate reduced ― 1.32s → 1.4s
- 0-2-2
- Rate increased ― 0.99s → 0.98s
Smart targeting now places spikes as far back on the track as it can, rather than directly in front of the Bloon closest to leaking (undocumented)
- 0-4-2, 0-5-2
- Now correctly works on splitting tracks (bug fix)
| “ | While we feel speed interactions for Spike Storm was a necessary evil for performance related concerns, we did not want to kill off self synergy contained local to the tower, so we are trying out an exception to this rule for the 042 crosspath. — Update notes |
” |
- 0-4-2, 0-5-2
- Ability: Now benefits from Smart Spikes' speed buff
- Selling Smart Spikes allows other towers to inherit Smart Spike's attack speed buff (bug)
- Resolved xx2 Spike Factory buff applying to other towers & allowing extra buffs to be applied (bug fix)
- 0-4-2, 0-5-2
- Smart Spikes start of round buff no longer applies to Spike Storm (undocumented)
| “ | Further balance for 401 crosspath, while this does already see some niche use it made sense to include increased explosion radius with the larger tower range. — Update notes |
” |
- Start-of-round attack speed buff duration increased ― 2.5s → 3s
- 4-0-2
- Explosion: Radius increased ― 30 → 40
- 5-0-2
- Large explosion: Radius increased ― 100 → 133
- Mini-explosion: Blast radius increased ― 30 → 40
- Spike Factory no longer can shotgun spikes for exactly one frame after spawning (bug fix)
| “ | Spike Storm is now exceptionally strong so the ability cooldown is increasing a small amount along with the T5 cost. This comes along with a crosspath rebalance granting more 042 lifespan. — Update notes |
” |
- 0-4-2, 0-5-2
- Ability: Long Reach duration bonus for spikes increased ― 50% → 100%
- Note: x-4-x spike duration changed from 15s-16.5s to 18s-22s
| “ | This update we’ve finally decided to nerf Permaspike by completely removing the ‘Far’ target priority from the earlier Smart Spikes upgrade. We know that this loss will be incredibly painful to deal with for the many spike factory enjoyers out there, so we have also included a couple other minor QoL adjustments to the Smart Spikes upgrade in a hopeful attempt to offset this. — Update notes |
” |
- Reworked targeting options ― Normal, Close, Far, Smart → Normal, Close, Smart, Set Target, Automatic
- Smart Spikes: Adds a "Set Target" option, which allows to select the place inside the Spike Factory's range where the spikes go to.
- Smart Spikes: Adds a "Automatic" option, attempts to directly target the first bloon
- Removed "Far" targeting option
