Shop

The Shop, formally called Gnome Shop in the first three games, is a game mechanic accessible from the game menu, where one-use items can be purchased with Gems, a currency primarily obtained by spending real money. It is exclusive to the mobile versions ( except Kingdom Rush: Frontiers, where it is also available on Steam). The Shop has a different product lining in every game, except the first two, which share the same items.

In Kingdom Rush: Vengeance and Kingdom Rush 5: Alliance, one-use items are bought from the Items menu, while the Shop is exclusively for the purchase of gems with real money.

Currency[]

The Shop uses Gems as currency, which can be obtained in three ways:

Each enemy, when killed, has a chance to drop a small number of gems.
Watch an advertisement for 100 gems.
Be bought with real money:
- $2.99: 1500 Gems
- $4.99: 2500 Gems
- $9.99: 6000 Gems
- $19.99: 14000 Gems
- $49.99: 40000 Gems

Gems carry over between levels. The player's current amount of gems can be seen near the top right corner of the main screen.

Items[]

Dynamite[]

(50 Gems)

Blast your enemies to pieces with these specially designed gnome explosives. Destruction guaranteed.

Deals 250 damage to enemies in an area of effect

Frozotov[]

(50 Gems)

This special concoction will freeze your enemies helpless in place for a while

Freezes enemies in place for 5 seconds
Cannot freeze Vez'nan while he's still in the tower.
Can freeze bosses, but they will thaw more quickly than non-boss enemies.
Enemies can't regenerate health when frozen.

Chill Wand[]

(250 Gems)

Freeze the world! The magic in this rod will freeze all baddies and prevent new ones from approaching

Freezes all enemies currently on the screen for 15 seconds.
Cannot freeze Vez'nan while he's still in the tower.
Only affects the normal attack wave; it does not stop special spawns:
- Spider Hatchlings and Mutated Hatchlings hatching from eggs.
- Skeletons and Skeleton Knights spawned from Graveyards.
- Magma Elementals spawned from the crater at the Forsaken Valley.
- Demon Spawns and Demon Hounds summoned by Vez'nan.
- Husks and Swamp Things spawned from the Poison Pool.
- Tainted Treants emerging from the ground at the Rotten Forest.
- Saurian Savants summoning Saurian Nightscales, Saurian Broodguards and Saurian Darters.
- Fallen spawned by Sand Wraiths and the God King.
Can freeze bosses (except Umbra), but they will thaw more quickly than non-boss enemies.
Enemies can't regenerate health when frozen.

Heartbox[]

(350 Gems)

Magical hearts trapped in a box. Break glass in an emergency to gain 5 extra lives

Adds 5 Lives to the player's current count.
Using a Heartbox on either Heroic Challenges or Iron Challenges will give you a few more lives to play with rather than just the one.
If a Heartbox is used to go over the standard 20 lives, a boss passing the exit will not result in a game over (as bosses take away 20 lives)

Gold Bag[]

(850 Gems)

Leave nothing to chance, bring extra gold to the battlefield.

Instantly awards 500 Gold
Gold Bags previously costed only 500 gems but were increased to 850 when the Endless Challenge was introduced, as a means to increase the difficulty of the mode by preventing people using multiple bags of gold in a level to get ahead.

Fat Boy[]

(999 Gems)

The big bad boy of bombs! You only need one of these to clear the battlefield and claim the spoils of war! Just tell us where to drop it!

Deals 3000 damage to bosses and mini-bosses. The damage ignores 1/2 of armor, just like Artillery.
If used on a level with a Graveyard, enemies will spawn en-mass from the site up detonation of the bomb.
Will not destroy all of the Shreds of Darkness created by Umbra.
