• Summary
  • The Push Trap is a trap in the Builder Base.
  • It pushes ground units through the air that are within its unit capacity, and has no effect on air units. Tapping on the Push Trap shows with an 'X' where affected troops will land.
  • It does no damage to units alone.
  • Upgrading the Push Trap only increases the number of unit capacity it pushes.
  • The Push Trap, like any other trap in the Builder Base, does not need to be re-armed.
  • The Push Trap does not need the Master Builder for construction, however, the Master Builder is required for upgrading.
  • The Push Trap can affect a certain number of ground troops, determined by its spring capacity. The spring capacity is the total spring weights of the units on top of the trap.
    • Skeletons spawned by the Drop Ship have a spring weight of 1.
    • Raged Barbarians and Sneaky Archers have a spring weight of 2.
    • Bombers have a spring weight of 4.
    • Boxer Giants and Cannon Carts have a spring weight of 8.
    • Night Witches and Hog Riders have a spring weight of 12.
    • Super P.E.K.K.As have a spring weight of 25.
    • While game files reveal that the Battle Machine has a spring weight of 25, the Battle Machine is effectively immune to Push Traps.

• Defensive Strategy
  • Use the push trap to push away Troops from critical buildings, like the Builder Hall or Defenses.
    • Try to push units into hazardous areas such as a Spring Trap, a Mega Mine or high-damaging buildings like the Crusher to do more damage to them.
  • You can use the Push Trap to push units into an empty space surrounded by walls to trap them inside.
  • Push Traps can be carefully placed to push enemies into another push trap. This is best done to high value Troops, like the Boxer Giant, to effectively stall an attack.
    • This also uses a lot of push traps, and is not recommended as there are better uses than putting multiple push traps.
    • You can purposefully upgrade a few push traps and use them to push units onto a lower level Push Trap. The higher level push trap would push more troops than the lower level push trap, effectively splitting up your opponent's units as some units cannot be pushed by the lower level one.
• Offensive Strategy
  • When going against this trap, try to use one expendable unit, such as a Raged Barbarian, to trigger this trap.
    • The push trap remains hidden before triggered, so you would have to predict where it is.
  • You can use the Battle Machine to trigger push traps as it does not affect it.

• Upgrade Differences
  • Push Traps undergo significant visual changes at level 3 and 6.
  • When initially constructed, the Push Trap is 3 uneven wooden boards held up by a spring with an arrow carved in the planks.
  • At level 2, four nails are screwed in at each corner.
  • At level 3, the arrow in the middle turns metal, and the wooden planks join, leaving no gaps between. The spring appears to be thicker and golden.
  • At level 4, the corners are now metallic, covering the nails.
  • At level 5, the corners connect through metallic stripes, and the nails turn bronze.
  • At level 6, the metallic stripes disappear and it becomes a golden version of level 4, but the nails stay bronze.
  • At level 7, the corners connect through golden stripes, and looks like a golden version of level 5.
  • At level 8, the wooden base is completely replaced with a blue base, similar to the arrow from level 3.
  • At level 9, the corners gain golden yellow spikes.

• Trivia
  • Although the Push Trap is rotated 90 degrees each time, it uses the Air Sweepers smaller rotation icon (the Air Sweeper rotates 45 degrees each time), rather than the Walls right angle rotation icon.
  • It can also push troops into walls. If that happens, then they will glitch to the side of the wall away from the Push Trap. In extreme cases, the Push Trap can even displace them to a corner of the base.
  • Troops pushed by the Push Trap, while seemingly moving in the air, can still be hit and be destroyed by defenses that only target ground. Also, Firecrackers and Air Bombs won't attack the troops while they are seemingly airborne.
