Kingdom Rush is a series of tower defense games set in a medieval fantasy setting. In line with the tower defense genre, each level presents a pre-determined path with spaces along the sides called 'Strategy Points', where the player can build towers. Enemies will come along the path in waves and it is the player's job to make sure the enemies are dispatched by towers before they reach the end. By spending the gold earned by defeating enemies you can upgrade towers, making them deal more damage or in the case of the barracks have more health. In each game there are four basic types of towers to strategize with; mage, archers, barracks, and artillery. Different enemies in the game sport resistances to certain types of damage, so which tower you put where is the lynchpin of a good level strategy. At the players disposal are spells that recharge over time. The reinforcements spell summons two brave soldiers to the path to block and deal damage to enemies, the meteor spell (called thunderbolt and soul impact in later games) calls down a rain of fire to blast away enemies.

Completing each level will give the player stars, a currency within the game to spend on upgrades. These star upgrades give a serious boost to spells, towers, and friendly units on the battlefield. After completing a campaign level with 18 or more lives remaining (out of 20), the player earns 3 stars and the Heroic Mode and Iron Challenge are unlocked for this level. These are more challenging modes that take place on the same path and impose various constraints. In these modes, the player will only be given one life, so any enemy surviving to the defense point triggers a failure. Heroic Mode and Iron Challenge reward one star each when completed.

The hero room and shop were introduced in an update to the original game on April 25, 2012.[5] To date the shop remains a feature only in the mobile versions of the game, and more than half of the heroes are behind an in app purchase. These hero units provide a huge boost in defense while playing, which affords the levels to be harder. They can be positioned anywhere on the path, and each have a unique style of fighting along with special abilities. The shop relies on the gem currency, only found in the mobile version of the games, and the player can purchase extra spells, power ups, or path clearing bombs to aid in beating levels.

All of Kingdom Rush's male characters as well as most lines said by towers are voiced by Sean Crisden,[6] while the female characters are voiced by Jennifer Ann Perry[7] and others. The game was featured in a problem in the 2012 Google Code Jam programming contest.[8]


The iOS version received an average score of 89/100 on review aggregator site Metacritic.[9] As of February 2015, Kingdom Rush is the most played game in the site with over 70 million plays, while Kingdom Rush: Frontiers with 25.6 million plays is situated in the 10th place.[12] Origins, the third game in the franchise captured similar reviews with a 96% approval by users according to Google, a 9.4/10 rating by CNET,[13] and a 9/10 by the game review site GamePitt.[14] The fourth game released in 2018, Vengeance, offered new innovations to the franchise's formula but remained true to form according to Polygon.

The target amount was reached within an hour, and subsequently reached over 5000% of the target.[32] The game, called 'Kingdom Rush: Rift in Time' is set after the events of the computer games, with the kingdom battling the 'Time Mage'.
