About
Caravan Keep is a free, single-screen tower defense game you can play in your browser, with no download or sign-up. Your desert caravan keep sits in the middle of the screen. Bandits and sand djinns walk toward it along four roads, and each enemy that gets through takes away keep health.
Waves 1 to 3 use one road; waves 4 and 5 use two, and wave 6 onward uses all four. Some bandits are armored from wave 6, and a bandit chief arrives every 10th wave. You start with 20 keep health. When it reaches zero, your journey ends and a new one begins at wave 1.
Build on the six tower spots around your keep. Four are open at first; you can unlock the two outer bastions with gold or the New Bastion card. Archer Towers fire fast arrows at one enemy, Catapults hit groups, and Sand Charms slow and sting nearby enemies. Towers shoot on their own after you build them. While the game is closed, the keep also earns idle gold.
How to play
- Tap or click an open tower spot to build a tower.
- Choose Archer Tower, Catapult, or Sand Charm when available.
- Spend gold to upgrade a tower, up to level 15, or sell it.
- Defeat enemies before they reach the keep and reduce its health.
- After each cleared wave, choose one of three cards to keep for the journey.
- Use the short break to prepare, or start the next wave yourself; it begins automatically after 8 seconds.
- Use the speed button to switch between normal and double speed.
- When the keep falls, spend the reputation you earned on permanent upgrades from the pause menu.
Tips
- Start with the four open spots and save gold for the towers you need.
- Catapults become available from wave 4, and Sand Charms from wave 7.
- Open the two outer bastions with 260 and 620 gold, or choose New Bastion.
- Keep defeating enemies to build your combo; it resets after about two seconds without a defeat and at the end of each wave.
- A combo of 8, 20, or 45 defeats in a row gives x2, x4, or x8 gold from kills.
- If you leave the game, return in the same browser to collect idle gold; storage is capped at 8 hours.
Cards and synergies
After every cleared wave, pick one of three cards. The 21 cards belong to Tower, Keep, Gold, and Combo kinds, with Common, Rare, and Epic rarities; many can stack, and some appear only after you hold another card. Thunder String calls lightning on every 10th tower hit, dealing four times the damage. With Thunder String, Golden Bolt makes lightning-hit enemies drop gold multiplied by your combo, while Rolling Thunder adds 3 to your combo with each lightning strike.
FAQ
Is Caravan Keep free?
Yes. You can play it for free in your browser.
Do I need to sign up?
No. You can start without signing up or downloading anything.
Can I play on a phone or tablet?
Yes. The game works on phones, tablets, and computers in portrait or landscape orientation.
Is my progress saved?
Your best wave, reputation, upgrades, settings, language, idle gold, and journey in progress are saved in this browser on this device. A journey is saved between waves, so after reloading you continue from the last break. Clearing site data removes the save.
What ends a journey, and what does reputation do?
A journey ends when keep health reaches zero. You earn reputation based on the waves you cleared, then spend it on permanent upgrades that carry over to new journeys.
How does idle gold work, and what is the 8-hour limit?
The keep earns gold while the game is closed, with storage capped at 8 hours; leaving for less than a minute earns nothing. When you return in the same browser, tap Collect in the Welcome back window to add the gold counted from the time you left.
How do cards and synergies work?
After each cleared wave, choose one of three cards to keep for the journey. Some cards stack, and some only appear when you already hold another card, creating synergies.
