Open Frontier

Open Frontier is a free strategy game made with AI by @kig, and you can play it right here in your browser.

A real-time war for the world.

You start as one tiny nation, painted onto a hand-drawn parchment map. Every second your population grows, your treasury swells, and your generals push for new ground. So do four rival empires.

Click an enemy tile to send your troops. Borders ripple outward in real time as territory changes hands. Manage your army-vs-economy split, time your attacks, and pick your moment to strike — the weakest neighbor today might be the empire that crowns you tomorrow.

Inspired by openfront.io and the great paper-map war games, Open Frontier is a fast-paced, one-sitting strategy game where every match is a new map and a new race for the crown.
