+
+```text
+Hi, I'm the developer of Ninelands, a small strategy game about building a realm on a board of nine lands.
+
+It started as a little board game experiment. My work colleagues and I got talking, philosophised about what makes a
+good game, and then simply got to work on our first prototypes of different games. One of them grew into Ninelands,
+which now runs on the web, desktop and Android.
+
+Its most popular mode has always been the map of the day: everyone plays the same map and compares how they did. That
+always felt like it belonged somewhere people can actually talk about it. So I built a daily edition for Reddit, and
+this subreddit is its home.
+
+How it works, in short:
+
+- A new 9×9 map every day, the same for everyone
+- Place your castle, farmers, knights and bishops, claim land and gold
+- Earn up to three stars, only your first game counts
+- Keep your streak, climb the daily leaderboard, and compare your realm in the comments
+
+**The first daily map goes live on December 1.** Until then, have a look at "How to play" and pick your faction.
+
+I'd love to hear what you think: ideas, questions, bugs, anything. Just comment below.
+
+See you on the board!
