How To Upgrade King Tower in Clash Royale

Clash Royale is a fast-paced strategy game where every decision matters, from the deck you build to how you defend your towers in battle. Each match puts you against another player in real time, using troops, spells, and buildings to break through enemy defenses while protecting your own Crown Towers and King Tower.

Your King Tower level is one of the most important progression systems in the game. It reflects your overall account growth and directly upgrades your tower’s health and damage. As your King Tower level increases, your defenses become stronger, giving you a real advantage against lower-level opponents and helping you survive heavier pushes in higher arenas.

In this guide, we’ll explain exactly how to upgrade your King Tower in Clash Royale, what actions give you the most experience, and how each King Tower level impacts your gameplay. Whether you’re just starting out or trying to push into tougher arenas, this breakdown will help you progress faster and make smarter upgrade choices.

How to Upgrade Your King Tower Level

Raising your King Tower level in Clash Royale is entirely tied to earning Experience Points, also known as XP. As you gain XP, your King Level increases automatically, and your King Tower upgrades along with it. There’s nothing you need to manually unlock for the tower itself, once you hit the required XP threshold, the upgrade happens on its own. While King Levels currently go all the way up to 70, the King Tower stops upgrading at level 15, which you reach once your account hits King Level 54.

The fastest way to earn XP is by upgrading cards. Every time you level up a card, you gain experience, and the higher the card’s rarity and level, the more XP you receive. Early upgrades on Common cards give very little experience, but upgrading Epic, Legendary, or Champion cards at higher levels can grant massive XP boosts in a single upgrade. This is why long-term progression often speeds up later in the game.

Card donations are another reliable way to grow your King Level over time. Donating Common cards gives a small amount of XP per card, while Rare and Epic donations reward significantly more. Even though the XP per donation feels small, regularly donating to clanmates adds up quickly and also gives you Gold, making it one of the best passive progression methods in the game.

A smart strategy many players use is upgrading cards they don’t actively play, especially up to mid-level ranges like level 10 or 11. These upgrades offer solid XP returns without costing extreme amounts of Gold. This lets you increase your King Tower level efficiently while keeping your main deck upgrades focused on competitive performance.

Requirements To Upgrade Your King Tower

King Level progression in Clash Royale is built around steadily increasing XP requirements, meaning the early game moves fast while later levels take much more commitment. At the start, leveling up feels almost instant. Reaching Level 1 only takes 20 XP, Level 2 requires 50 XP, and Level 3 needs another 50. This light XP curve continues through the early stages, with players reaching around Level 10 after earning just a few hundred total XP, as Level 10 itself only requires 200 XP to unlock.

Once you move into the mid-game, the grind becomes more noticeable. By the time you reach Level 20, you’ll need around 1,400 XP for that single level. At Level 30, the requirement jumps to roughly 7,000 XP, and Level 40 pushes that number up to about 22,000 XP. By the time you approach Level 50, the total XP you’ve earned across your entire account adds up to around 403,770 XP, marking a major milestone in progression.

After Level 50, XP requirements spike sharply. Level 51 alone demands an additional 40,000 XP, and the climb becomes significantly slower from there. To reach Level 54, which unlocks the maximum King Tower level of 15, you’ll need about 85,000 XP for that final stretch. At this point, progress relies heavily on high-level card upgrades and consistent donations, making long-term planning and resource management essential for pushing your King Tower to its maximum strength.
