Tower defense is a subgenre of real-time strategy video games. The goal of tower defense games is to try to stop enemies from crossing a map by building traps to slow them down and towers which shoot at them as they pass. Enemies and towers usually have varied abilities, costs, and upgrade prices. When an enemy is defeated, the player earns money or points, which are used to buy or upgrade towers, or upgrade the number of money or points that are earned, or even upgrade the rate at which they upgrade.
The choice and positioning of the personal towers is the essential strategy of the game. Many games, such as Flash Element Tower Defense, feature enemies that run through a "maze", which allows the player to strategically place towers for optimal effectiveness. However, some versions of the genre force the user to create the maze out of their own towers, such as Desktop Tower Defense. Some versions are a hybrid of these two types, with preset paths that can be modified to some extent by tower placement, or towers that can be modified by path placement.

Famous quotes containing the words tower and/or defense:
“Resignedly beneath the sky
The melancholy waters lie.
So blend the turrets and shadows there
That all seem pendulous in air,
While from a proud tower in the town
Death looks gigantically down.”
—Edgar Allan Poe (1809–1849)
“There’s no telling what might have happened to our defense budget if Saddam Hussein hadn’t invaded Kuwait that August and set everyone gearing up for World War II½. Can we count on Saddam Hussein to come along every year and resolve our defense-policy debates? Given the history of the Middle East, it’s possible.”
—P.J. (Patrick Jake)
