One island. Two castles. No waiting.

You and your rival look out from opposite ends of the same island. Nobody takes turns: both of you attack and defend at once, and a battle is over in five minutes.

The whole island from above: a castle at each end, a river and a bridge in the middle, two armies meeting
  1. Spend your war chestScout their castle, then spend a secret budget on your opening army.
  2. Reinforce as supply flowsSupply trickles in. Buy more troops, siege engines or your own defences.
  3. Break the keepUnits and engines fight by themselves. The first keep to fall loses.

Walls fall. Rubble becomes a ramp. Nothing is safe.

Siege units have hard counters, a castle can be breached in many places, and every stone you knock down is a road for your army.

Questions

Is it free?

Yes. Open the game in your browser and play. There is nothing to install.

Can I play on my phone?

Yes, it is built for phones, in landscape. iOS and Android apps are on the way; until then it runs in your phone's browser.

Can I play with a friend?

Yes. Open a private room, share its four-letter code and fight. You can also take on a bot at three levels, or march through the campaign.

How long is a battle?

Five minutes. If the keeps are level when time runs out, a sudden-death overtime of up to two minutes follows: the first keep damage wins.

What about 2v2 and the ranked ladder?

Both are on the way. For now it is one against one, in private rooms and against bots.

Their keep is waiting.
