Understanding Elixir Math In Tower Rush

Players who treat the game purely as a test of reflexes will inevitably hit a skill ceiling they cannot break without learning the underlying mathematics.


To truly master the genre, you must stop looking at units as 'characters' and start viewing them as numerical investments.

Generation Rates and 'Leaking'

The only way one player can mathematically gain an advantage is if the other player 'leaks' elixir by sitting at the maximum cap of 10.


If your bar reaches 10 and you do not play a card for 2. Here's more information about tower rush have a look at the page. 8 seconds, you have permanently lost one unit of energy that you can never recover.

Never sit at 10 elixir unless you are waiting for a very specific enemy push to cross the river.You must increase your Actions Per Minute (APM) significantly to keep up.You are essentially fighting a 10v7 battle.
Calculating Positive Trades

The entire goal of defensive play is to execute 'positive elixir trades', where you spend less energy to destroy a push than the opponent spent to create it.


Conversely, if you panic and use a Rocket (6 elixir) to kill a Princess (3 elixir), you have suffered a -3 negative trade.

Trade ScenarioElixir MathOutcomeUsing The Log (2) to kill a Goblin Barrel (3)3 - 2 = +1A slight positive trade; highly repeatable and safeUsing a Lightning Spell (6) to kill a lone Musketeer (4)4 - 6 = -2A terrible negative trade; only acceptable if the lightning also hits the tower to win the game
The Invisible Scoreboard

When you are up by 4 elixir, the game is no longer a strategic duel; it is an execution.


Launch your win condition, support it with a spell, and watch them fail to defend because they simply do not have the currency to buy troops.
