Kingdom Rush 6 on iPhone and Android

$6.99 on the App Store and Google Play. The big difference from Steam is that some heroes, towers and spells are sold separately instead of unlocked by stars.

Free with the app

Heroes: Gerald, Zefira, Bolin, Connor. Towers: Archer Garrison, Knights Order, Royal Catapult, Scholar Mage, Dwarven Culverin, Elven Elite Ranger, Gold Prospectors, Sunray Master, Cursed Crossbows, Light Priestess. Spells: Reinforcements, Rain of Fire, Royal Edict, Ace Musketeers. These still unlock with stars, the same way as on Steam.

The rest are in-app purchases. The price page lists them, and the loadout planner marks them as you pick.

Requirements

• iPhone and iPad: iOS 13.0 or later, about 527 MB, rated 9+.
• Android: Android 7.0 or later.

Google Play Pass

Asked whether the game was coming to Play Pass, Ironhide replied “Yep, it's coming this monday on Play Pass!”, which puts it on September 28, 2026. Play Pass is a subscription, so the game is playable there for as long as it stays in the catalogue.

APK downloads

The only official Android build is the one on Google Play. APK and “mod APK” files on other sites are not from Ironhide, and a modified APK can carry anything. If you want it without buying it outright, Play Pass is the legitimate route.

Is it on Apple Arcade?

No. On iPhone and iPad it is a regular paid App Store app, not part of Apple Arcade.
