It is incredibly satisfying to see the damage numbers of your favorite troop increase, knowing it will hit the enemy tower slightly harder.

Entering a match with a King Tower that is one level lower than your opponent puts you at a massive, permanent mathematical disadvantage before a single card is even played.
Why the Numbers Matter
For example, a level 11 Princess tower might require three shots to kill a level 11 Goblin.

This single extra shot changes everything. If you want to learn more information in regards to tower rush review the web site. If a Goblin Barrel lands on your level 10 tower, those goblins will survive significantly longer, resulting in hundreds of extra points of chip damage over the course of the match.
A +1 King level advantage usually equates to roughly 300-400 extra hitpoints on each Princess tower.Higher level towers kill Minions and Skeletons much faster.Always prioritize donating to your clan. The Psychological Advantage
This often induces a sense of 'ladder anxiety' in the opponent, causing them to play overly aggressively to try and overcome the mathematical deficit, leading to fatal mistakes.

You know that your towers can absorb a few extra hits from a stray Miner or a predictive Fireball without crumbling.
