Levels

Levels are Tower Defense Simulator's internal experience system. Each player starts at Level 0, but as they play through the game, they will earn EXP, allowing them to reach higher Levels. Higher Levels require higher amounts of EXP to reach. Reaching certain Levels unlocks new parts of the game or grants the player special rewards. The amount of EXP needed to level up can be seen in your Level Bar at the bottom of your screen in the lobby.

Exp Requirements

Below lists the formula for levelling up.

Levels	EXP Required
$0\to 10$	$45+(\text{Next Level}\times 3.5)$
$10\to 40$	$\text{Next Level}\times 8$
$\ge 41$	$260+(\text{Next Level}\times 1.5)$

Prior to the Overhaul Update, the formula was as follows:

Levels	EXP Required
All	$35+(\text{Current Level}\times 2.5)$

Rewards

Prior to the Skill Tree Update, every fifth Level increased the amount of base health you had by 2, unless the map or mode had the HP Locked modifier. Prior to the Overhaul Update, each Level increased base health by 1. Before 18th of June 2019, Levels did not increase base health. The Overhaul Update formula for calculating base health was:

$100+(\frac{\text{Player Levels}}{5}\times 2)$

Reaching some Levels also unlock new towers, like the Crook Boss or Turret, while other thresholds unlock new parts of the game, like special maps or Hardcore mode. The list below lists all current rewards or unlocks at the given level.
