• Summary
  • The Spring Trap is a defensive trap in the Builder Base that springs ground units off the map. The units will appear to fly to the top of the screen then fall down.
  • The Spring Trap does not need the Master Builder for construction, however, the Master Builder is required for upgrading.
  • The Spring Trap can spring a certain number of troops, depending on its spring capacity. The spring capacity is the total spring weights of the units on top of the trap. Higher leveled Spring Traps have a larger spring capacity, allowing them to launch more troops at once.
    • Raged Barbarians, Sneaky Archers and Skeletons have a spring weight of 1.
    • Bombers have a spring weight of 2.
    • Boxer Giants and Cannon Carts have a spring weight of 5.
    • Night Witches and Hog Riders have a spring weight of 12.
    • The Super P.E.K.K.A has a spring weight of 25 and is thus entirely immune to it.
    • Internally, Battle Machine has a spring weight of 20, though it is also immune to this trap.

• Defensive Strategy
  • Spring Traps can be combined with Push Traps by facing Push Traps toward the Spring Trap. This is useful in eliminating distraction troops like Boxer Giants, so that your defenses will focus on the other enemy troops.
  • Grouping Spring Traps isn't recommended, since only a few small troops like Raged Barbarians can trigger them easily.
  • Spring Traps do not trigger a troop's ability if it requires the troop to be destroyed. For example a Cannon Cart will not activate Last Stand when it was bounced.

---

• Upgrade Differences
  • At level 1, the Spring Trap appears to be a wooden board on a metal spring.
  • At level 2, the Spring Trap's spring becomes much thicker,and the wood also becomes much wider and thicker.
  • At level 4, the Spring Trap gains a metal border around the board's edges.

• Trivia
  • The Spring Trap gains more spring capacity per upgrade and has a higher maximum spring capacity than its Home Village counterpart, but begins with fewer.
  • The Spring Trap can fail to trigger properly if a Raged Barbarian's rage ability is active and he simply ran past the trap without stopping.
