Updated for Town Hall 18 (October 2026).
The Bomb is the first trap you unlock in Clash of Clans: a hidden 1×1 explosive that goes off when ground troops step near it and splashes every ground unit within 3 tiles. You get two at Town Hall 3 and eight from Town Hall 14. Its max level is 14 (Town Hall 18) with 200 damage, which is small next to the other traps but plenty for Wall Breakers, Goblins, Archers and Skeletons.
How the Bomb works
A ground troop that comes within 1.5 tiles lights the fuse, and moments later the Bomb explodes, damaging every enemy ground unit within 3 tiles. Air units are never hit. Because there’s a short gap between trigger and blast, it does the most damage where troops stop and stand, such as right beside a building they’re attacking or a Wall they’re breaking.
Like the Giant Bomb, the blast knocks back small ground troops of 3 housing space or less; bigger troops barely move. A triggered Bomb stays spent after a normal multiplayer defense until you log in and it re-arms for free. Bombs don’t count toward an attacker’s destruction percentage, so nobody has to find them to get 100%.

Where to place Bombs
- On Wall corners and junctions. Wall Breakers head for those spots, and a Bomb of the same level kills one in a single blast. This won’t stop Super Wall Breakers.
- Along the outside of your Walls, tucked behind the buildings that sit outside them. Troops gather while they clear those buildings and are bunched up when they reach the Wall.
- Between two resource collectors. Goblins run from one to the next, and two or three Bombs on that line can delete the whole group.
- Around the Town Hall. Bombs still go off on invisible troops, so they catch Sneaky Goblins dropped by a Battle Blimp trying to snipe the Town Hall.
- Where Witch attacks will pass. From level 4, a Bomb kills a group of summoned Skeletons in one blast, though Skeletons can’t set it off by themselves.
Pairing several Bombs with a Spring Trap at the entrance of a defensive pocket makes a good Giant trap. Move a Bomb while you upgrade it: attackers can see it, and it won’t trigger until the upgrade is done.
How to deal with Bombs when attacking
Lead with something that can take the hit. A Giant or other tank soaks a Bomb with little loss, while a big stack of Archers or Goblins can be wiped out. If you think a Wall junction is bombed, send one Barbarian at it before your Wall Breakers. Air armies can ignore Bombs entirely. Witch players should remember their Skeletons won’t clear Bombs, so a Bomb set off later by a bigger troop can still kill all the Skeletons at once.
See the Home Village traps page for every trap.
