AI Overview: If Clash Royale keeps crashing, update the game and your phone, free at least 2 GB of space, restart, and switch networks. Reinstall only after you save your account with a Supercell ID. The older 100 MB storage advice is out of date, because the App Store lists the game at 1.1 GB. If it still crashes, use Help and Support.

- Save your account with a Supercell ID before you reinstall.
- The game needs iOS or iPadOS 14.0 or later on Apple devices.
- If the game will not install at all, read the not compatible fixes first.

Why Clash Royale Crashes
Here’s the thing: when Clash Royale keeps crashing, the game is closing on its own. In most cases the phone ran out of memory or space, the game was out of date, or the connection dropped at the wrong moment. A few cases come from a store glitch or a damaged install, and those are the ones that need a reinstall.
The short version: work from the cheapest fix to the most costly one. The catch: reinstalling is the most costly, because you can lose the login link if the account is not saved.
What changed: this page said 100 MB of free space was enough, and that 0.5 GB of RAM and Android 4.0.3 would run the game. The App Store now lists the game at 1.1 GB and iOS or iPadOS 14.0 or later. What it means: a phone with a nearly full drive crashes more often than before. Still unknown: the exact RAM floor, since sources disagree.
Game files grow with new cards, arenas and effects. If the next big update adds more, low-memory phones are the first to crash. The negative effect: players on older devices may face more crashes after each big update and get little warning.
Quick math: at 1.1 GB for the game itself, a phone with 1 GB free cannot even finish an update, because the new files have to sit beside the old ones. What it means: if crashes began right after you filled the phone with photos or video, free space is the first thing to fix.
Nine Fixes, in Order
- Restart the phone. Hold the power button, choose Restart, or turn it off and on.
- Update the game. Open the App Store or Google Play and check for a Clash Royale update.
- Update the system. iPhone and iPad need iOS or iPadOS 14.0 or later.
- Free space. Aim for at least 2 GB free, since the game lists 1.1 GB.
- Close other apps. Video and map apps use a lot of memory.
- Fix date and time. Turn on automatic date and time.
- Switch networks. Try Wi-Fi, then mobile data, and turn off any VPN.
- Clear the Play Store cache on Android: Settings, Apps, Google Play Store, Storage, Clear cache. Reinstall the game only after your account is saved.
- Contact Support. Open Settings, then Help and Support, and describe the crash.
The move: before step 8, register a Supercell ID. Our save and load checklist shows how, and it takes two minutes.
Which Fix for Which Crash
| What happens | Likely cause | Try first | Time |
| Crashes on the loading screen | Old version or full storage | Update, then free space | 5 minutes |
| Crashes mid-battle | Low memory or a dropped connection | Close other apps, switch networks | 3 minutes |
| Crashes after an update | Damaged install | Restart, then reinstall (account saved first) | 10 minutes |
| Crashes only on mobile data | Network or VPN problem | Turn off the VPN, try Wi-Fi | 2 minutes |
| Will not install | Device check failed | Read the not compatible fixes | 10 minutes |
The takeaway: most crashes are fixed by step 4. Free space is the one most players skip. The catch: do not clear the game’s data as a fix unless the account is saved, because that removes the link on this phone. After each step, open the game once and play a short battle, so you know which step worked.
When It Is Not Your Phone
The pattern: sometimes the servers are the problem. Supercell runs maintenance breaks, and the game may not load during one. If many players report the same thing at once, wait before you reinstall. The catch: checking port 9339 with a web tool, which is kept below as part of the original text. Treat that as a community tip, because Supercell does not list it.
If crash reports rise after each update, expect Supercell to post more fixes after launch day. The negative effect: players who reinstall in a panic during an outage can lose time and, if the account is not saved, the login link.
Phones and operating systems change faster than game files, so a fix that works this month can stop working after the next system update. The negative effect: players who update their phone but not the game may swap one crash for another.
The fallback: if the game never installs, read the not compatible fixes and can’t find Clash Royale. A modern computer is another option: our PC guide shows how to play on Windows.
