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, unless you play the Android version through Google Play Pass.

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

The Android version is on Google Play Pass. A subscriber gets the game with no in-app purchases, and players report that the heroes, towers and spells the paid app sells unlock with stars instead, as on Steam. Kingdom Rush 6 on Play Pass compares it with the paid app and Steam, and covers what to do if you bought items before it arrived.

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. Play Pass is the legitimate way to play it without buying it outright.

Is it on Apple Arcade?

No. On iPhone and iPad it is a regular paid App Store app, not part of Apple Arcade. Earlier Kingdom Rush games did get Arcade versions later; Kingdom Rush 6 and Apple Arcade has how long each one took.
