==Summary==
*​The Spring Trap bounces enemy ground troops off the battlefield, effectively instantly destroying them, depending on their housing space occupation. Each Spring Trap can bounce off a certain number of housing space worth of troops; upgrading the Spring Trap increases its capacity to launch troops.
**For the purposes of determining interactions, subtroops are worth a certain amount of housing space. A Skeleton, whether spawned by a Witch or Skeleton Spell, takes up 1 housing space. A Yetimite takes up 3, a Golemite takes up 6, and a Big Boy takes up 20.
*Like other traps, the Spring Trap requires re-arming after it has been activated. Doing so is free and occurs automatically once the player logs into the game.
*The Spring Trap is unable to affect troops that take up more housing space than it can launch. As the max level Spring Trap has a capacity of 18 housing space, troops with more than 18 housing space are unaffected, such as the P.E.K.K.A or Golem. The Spring Trap also has no effect on Heroes or Pets.
*The Spring Trap has a short activation delay. Units with a movement speed of 32 or above, such as the Goblin, can move across it unaffected unless they stop on top of the trap. Units that are slightly slower, such as an Archer, can also avoid the trap by simply passing over a corner of the Spring Trap's tile.
==Strategy==
===Defensive===
*If put in a strategical way, Spring Traps can ruin a raid, including the infamous Giant-Healer combo as it will destroy many Giants, significantly reducing their potential DPS.
*Spring Traps can be placed near or around the Town Hall, so you can get rid of large numbers of Troops closing in.
*A sound strategy for Spring Traps is to place them in an intentionally-designed gap. As troops will generally tend to go through the gap rather than fight their way through the Wall, they will be directed right over the Spring Trap and be bounced to their death. Remember, Spring Traps are one-time-use and until being re-armed it will leave an undefended gap in the Wall after an attacker has triggered it.
**A modified version of this strategy is to place Walls inside your base so that the enemy Troops have to walk over the Spring Trap to attack nearby buildings.
*You can also place them in front of commonly-targeted Walls to stop Wall Breakers from breaking them, forcing the attacker to deploy a second wave if they have one or be disadvantaged in the attack. However, this fails to deter Super Wall Breakers, as the Spring Trap will instead instantly trigger its Mega Bomb ability.
*You can place them in between to take out Giants or place them in between to take out Goblins.
*Some Spring Trap upgrades are better than others, even though each upgrade adds the same amount to its maximum capacity. Upgrading the Spring Trap to level 4, for example, enables the Spring Trap to launch an Ice Golem, 2 Valkyries, 3 Giants, a Druid, or 3 Hog Riders, one more than at the previous level. This contrasts with upgrading it to level 3, which does not majorly change its interactions with ground units (only really springing off two extra Barbarians or similar troops).
*Troops with abilities that activate on their destruction can still activate these abilities when getting bounced off a Spring Trap. For example, if an Ice Golem is launched, it still freezes nearby structures and enemy troops since it was technically defeated on the spot.
===Offensive===
*If you suspect that a certain location (such as a gap in the ) has a Spring Trap, try to trigger the trap by using high housing-space units such as a P.E.K.K.A or Golem since the Spring Trap will not be able to affect these units (or launch many of them, if they are able to do so). The Barbarian King can be used for this purpose as well, as he too is unaffected. If you have neither, try to trigger it with a single expandable troop, such as a Barbarian.
*Spring Traps are unable to fling Heroes and Hero Pets away, since they are over 18 housing space. This makes them an amazing counter to Spring Traps.
==Upgrade Differences==
*The Spring Trap undergoes significant visual changes at level 3 and 5.
**When first constructed, the Spring Trap consists of a wooden plank and brass spring, with one end of the spring attached to a wooden disc (which is fixed to the ground by nails) and the other fixed to the plank.
**At level 3, the Spring Trap's spring becomes a lot thicker, as well as the wood.
**At level 5, the Spring Trap now has encased metal reinforcements on the edges.
