Updated for Town Hall 18 (October 2026).
The Push Trap is a hidden Builder Base trap that throws ground troops 6 tiles in the direction its arrow points. It does no damage by itself; its job is to knock attackers off their path, into walls, or onto another trap. You get your first one at Builder Hall 2 and up to five by Builder Hall 7, and each level raises the spring capacity, which decides how heavy a troop it can launch.
How the Push Trap works
When a ground troop steps within 1 tile of a hidden Push Trap, it springs and launches every eligible ground troop within 3.5 tiles. Tap the trap in your base and an X shows where those troops will land. Air troops are never affected.
Spring capacity is the part most players get wrong. It does not cap the total weight the trap can throw. It sets the heaviest single troop the trap is able to push. A level 8 Push Trap (capacity 22) can throw two Power P.E.K.K.As at once even though together they weigh 44, because each one weighs 22.
Like every Builder Base trap, it re-arms on its own after each battle. Placing a new Push Trap does not take a builder, but upgrading it does. Since the April 27, 2026 update, a Hammer of Building also works on Builder Base traps.
Spring weight of each Builder Base troop
A troop can only be pushed if its spring weight is at or below the trap’s capacity. These are the current Builder Base 2.0 weights:
| Troop | Spring weight | Push Trap level needed |
|---|---|---|
| Skeleton (from Drop Ship) | 1 | 1 |
| Sneaky Archer | 3 | 1 |
| Raged Barbarian | 4 | 1 |
| Bomber | 12 | 3 |
| Hog Rider (from Hog Glider) | 12 | 3 |
| Night Witch | 14 | 4 |
| Electrofire Wizard | 14 | 4 |
| Cannon Cart | 16 | 5 |
| Boxer Giant | 18 | 6 |
| Power P.E.K.K.A | 22 | 8 |
| Battle Machine | 25 | Never pushed |
Push Trap levels
| Level | Builder Hall needed | Spring capacity | Cost (Builder Gold) | Build time |
|---|---|---|---|---|
| 1 | 2 | 8 | 1,000 | None |
| 2 | 3 | 10 | 3,000 | 5m |
| 3 | 3 | 12 | 10,000 | 20m |
| 4 | 4 | 14 | 20,000 | 2h |
| 5 | 5 | 16 | 40,000 | 4h |
| 6 | 6 | 18 | 60,000 | 12h |
| 7 | 7 | 20 | 100,000 | 16h |
| 8 | 8 | 22 | 200,000 | 1d |
| 9 | 9 | 24 | 300,000 | 1d 12h |
| 10 | 10 | 26 | 500,000 | 2d |
Number of Push Traps by Builder Hall: 1 at BH2, 2 at BH3, 3 at BH4, 4 at BH5 and 5 from BH7. Level 8 is the one to aim for, since 22 capacity covers every troop the trap can ever move. Levels 9 and 10 raise the capacity past the heaviest troop it can move.
Where to place Push Traps
- In front of the Builder Hall or your strongest defenses, pointing outward, so the push undoes the troops’ progress.
- Aimed at a hazard: a Spring Trap, the slam zone of a Crusher, or a walled pocket where troops get stuck.
- At the edge of a short-range defense’s reach, pointing inward, to drag a Cannon Cart in Mortar Mode into range. This needs at least a level 5 trap.
- Away from your Mega Mine. A push can carry troops out of the blast before it goes off.
Chaining one Push Trap into another can stall a Boxer Giant for a long time, but it spends several traps on one lane. A cheaper trick is to leave one trap at a lower level: a high-level trap throws a mixed group onto it, and the low-level one only launches the lighter troops, splitting the army.
How to deal with Push Traps when attacking
- Send one cheap troop, such as a single Raged Barbarian, down the lane you suspect first to set it off.
- Walk the Battle Machine through likely spots. It triggers traps but cannot be pushed.
- Go air. Push Traps ignore all air troops. Pushed ground troops stay ground targets in mid-flight, so Firecrackers and Air Bombs still cannot hit them.
- Watch where your Sneaky Archers get thrown. A push away from their target burns their cloak time; a push toward it usually costs nothing.
Push Trap changes since Builder Base 2.0
- May 15, 2023: Push Traps can now push jumping units, so the Hog Glider’s Hog Rider is no longer safe.
- June 12, 2023: fixed pushes that could throw troops off the map when the landing spot was boxed in by walls.
- April 27, 2026: Hammer of Building can now be used on Builder Base traps.
The Builder Base 2.0 guide covers how traps are split across Stage 1 and Stage 2.
