About Crystal Keep
Crystal Keep is the kind of pick-up-and-play title you end up replaying far longer than you planned. The hook here is right there in the name: protect the crystal vault. You are reading the incoming waves and spending wisely, because one weak corner is all it takes. Players who like a clean, honest challenge with no fluff will get the most out of it. Best of all, it runs right in your browser on desktop and mobile, with no downloads and no sign-up.
🎮 How to Play

- Towers auto-shoot nearby 💀 enemies
- Earn 💎 coins by defeating enemies
- Don't let enemies reach your base!
- Survive all waves — bosses appear every 5 waves!
Tip: on a phone, tap the screen; on a computer you can usually use your mouse, the spacebar or the arrow keys.
