About:

Sky Settlers is a minimalist city builder game, where you have different cards that you can play to build structures. Each tile has connections to other tiles, that give the player either more or less points depending on what tiles are around that tile.
For example: A windmill will give you more points, if you place it near other windmills or wheat fields. But it will give you less points, if you place it near a mountain.

Quest Cards:

After buying an island, you can choose one of two quests that are offered to you. These quest cards function like normal tile cards, but they create a quest pattern, that when completed rewards you. The rewards can be just points, but sometimes you can get new cards into rotation. But there is a catch. These quests can give you Disaster Cards when placed. What are those?

Disaster Cards:

These cards do exactly what it says. When played, a disaster will occur. These disasters are different and there are a lot of them. For example: an earthquake will shake a random island, destroying tiles that you have built there.
