The concept is devilishly simple: fill your deck with multiple fragile, high-damage swarm units that all share the exact same weakness.

If you bring a Goblin Gang, a Princess, and a Goblin Barrel, the opponent desperately needs a cheap spell (like The Log) to deal with all of them.
Forcing the Error
They are forced to use their Log to kill her. If you are you looking for more in regards to tower rush look at the web-page. The exact millisecond you see that Log roll across the screen, you deploy your true win condition: the Goblin Barrel.

Because their Log is now out of rotation, the Goblin Barrel lands directly on their tower and deals massive damage before they can cycle back to another counter.
However, if you use it on defense, they will Log it, meaning you can instantly counter-attack with the Barrel.Always include an Inferno Tower or Bomb Tower.You can often throw a Barrel, force their spell, and cycle back to a second Barrel before their spell returns. The 'Tricky Barrel' and Advanced Mind Games
The opponent, acting on muscle memory, will blindly drop their Log in the center of the tower, missing your goblins entirely as they spawn safely in the back.

It is a high-stakes game of poker, played entirely with goblin projectiles.
Win ConditionHow to AttackStandard Goblin BarrelPlaced dead-center on the tower for maximum immediate damage; used only when spells are out of rotationThe Tricky BarrelPlaced two tiles behind the tower to dodge predictive spells; used to break established muscle-memory patterns The Mental Victory
When executed perfectly, the opponent will feel like they never have the right cards in their hand at the right time.

The bait is set; wait for them to bite.
