Hexhold

Every day there's a new island of grass, forest, mountains, a river and the sea, and everyone gets the same 20 buildings in the same order. Tap a grass hex and a ghost of the building shows the points it would score; tap again to build. Buildings score from what's next to them — farms like empty grass, mines like mountains, taverns like homes, and the castle counts everything joined to it.

You can see the next two buildings and everything still to come, so planning pays: a careful kingdom scores about 13% more than taking the best spot each time. One ranked go a day, worked out again on our server so the board is honest, plus unlimited practice islands with undo.
