# Hearthsea

Hearthsea is a free Catan-style board game you play in the browser, made by an individual developer. It includes a Cities & Knights expansion with three short hands-on tutorial lessons (commodities and the event die, knights and the barbarians, progress cards), and you can also play a full game against AI bots.

## Description

Hearthsea is a browser board game in the Catan style, developed by an individual creator who is currently asking for playtesters. It offers a Cities & Knights expansion, and the developer recently added three hands-on tutorial lessons covering commodities and the event die, knights and the barbarians, and progress cards, taking roughly eight minutes in total. Players can go through the tutorials on a laptop or phone, then try a full Cities & Knights match against bots. The game is free to play, and the author says it was made with AI.

## Original post

[Browser] Never played Cities & Knights? I need you to test my tutorial for it (free board game, made with AI)

I make Hearthsea, a Catan-style board game you play in the browser. A player told me this week that Cities & Knights made no sense to someone who'd never played it, and they were right. So I added three short hands-on lessons: commodities and the event die, knights and the barbarians, and progress cards. About 8 minutes in all. I'd like someone who doesn't know Cities & Knights to go through them and tell me where they got lost. How to test Open https://hearthsea.com on a laptop or phone Open Tutorial, then the Cities & Knights group, and play the three lessons If you have time, play one Cities & Knights game against the bots What I want to know After the lessons, could you follow a real game, or were you guessing? Which step made you go "wait, what?" Was there anything on screen you couldn't find? It's free. I'll answer every comment, and if a line is unclear I'll rewrite it. That's already happened once this week: someone screenshotted a lesson that said "card" before ever explaining what a card was.   submitted by   /u/herXhim_official   to   r/playtesters [link]   [comments]
